Re: [Elecraft] Question about 120 volts vs. 240 volts house supply to KPA 500

[Rick Bates, nk7i]

I would check on the code about the unganged breakers for a 240V 
circuit.  It may not meet the code.  (ALL of my 240 circuits have ganged 
breakers; as a reference.)


Even if it does meet code, if one 'popped' and the other did not, one 
side of that circuit would still be hot, therefore unsafe if worked on 
or problem causing to whatever is connected.  A ganged breaker would 
mean that if one 'popped' it would shut the other breaker off, removing 
ALL power to that circuit.


Part of my former career was to do business inspections; this I would 
refer to a qualified electrician, a world I attempt to avoid as much as 
possible.  I know enough about electricity, to leave it alone hi hi.

service from L1, and a second 120 volt service from L2. Thus there is 
also a 240 volt service, L1 + L2,  for the amp or any amp, past and 
present. Thus everything in the station shares a common Neutral and 
common Ground.  Many issues are resolved using this approach. 
Besides, our house was wired with those stab on outlets, of which I 
have had to replace many due to poor connections.


Yes I know that #10 is rated for a 30 amp service. Due to the length 
of the run from the breaker panel to the desk, I choose a larger 
gauge of wire to assure less voltage drop.  Besides, crawling through 
the attic pulling a #10-3 is the same effort as pulling a #12-3.  At 
the breaker panel, the service is protected by 2 individual 20 amp 
breakers.  I did not use a ganged 2 pole breaker.


No ground issues, no hum issues, no buzz issues and no RFI issues.

Re: [Elecraft] Question about 120 volts vs. 240 volts house supply to KPA 500

[Rick Bates, nk7i]

Owning and having used both KPA500 and KPA1500; there are absolutely 
times that 'only 3 dB' is the difference as shown in a logbook.  😉


The KPA1500 is online, the KPA500 is stored for portable (RV) use); for 
that very reason.


You must overcome the noise (and other signals) at the other station to 
make the contact; sometimes that simply means raw power out.

Re: [Elecraft] Soundcard choice for K3s on Linux help needed

[Rick Bates, nk7i]

I submit that using the mobo sound card for radio, is a poor choice.

The OS will use it (if it is using the GUI, not text only); which means 
tones, belches, tunes and other can be transmitted (incidentally or 
not).  If you listen to FT8, you'll often hear TV, pets, local room 
chatter; OS noises and worse (a violation in the US, it's not the phone 
band).  Much of that 'stuff' is also at full bandwidth (2700 Hz wide).


The K3S has an internal sound card (USB), which makes wiring simpler; 
it's also the com port cable.  Some K3 have the updated I/O card, but K3 
that are not updated will need a sound card for digital.


It's best to use another sound device; that insures audio isolation.  
Even the cheapest add on will work, at only a minor expense; then put 
the radio apps to THAT device and let the OS do it's thing on the mobo 
sound card and keep the spectrum, less 'busy'.

Re: [Elecraft] K4D compatibility

[Rick Bates, NK7I]

Not to mention that the updates to all HRD modules, are four years 
(PLUS!) behind the promised release date (now ONLY the logbook update is 
mentioned; THEN other modules, like K4 control perhaps someday...).


I'm migrating to DXLabs, but (being polite) it's a 'process' (tedium 
YOWCH!) but Win4K4 has the 'prettiest' rig control app, so far (while 
waiting for VK4).  No one suite, is complete, pretty or effective so 
it's still a hodge podge of display filling panels, more than the 
display can show at one time (even on a 4K monitor).  There is so much 
needing to be seen, I'm adding another monitor, hoping that helps.


If only the apps each spoke a common language, so mix and match wasn't 
so complicated (or impossible); but the variables in each station is 
complex.  (THEN add remote ops from a multiplatform system...)


It's no wonder I still prefer twisting knobs and mashing buttons, hi 
hi.  Simple just ROCKS!

Re: [Elecraft] KPA500 ISSUE

[Rick Bates, nk7i]

G'morning,

That the amp does occasionally reach 500 out hints that it's not the 
issue; but the rig driving the amp.


You didn't mention the rig, but watch what it is putting into the 
KPA500.  It could be as simple as an output calibration.


I would DEFINITELY verify that the TX audio into the rig, is correct 
(high enough for full output, but not high enough for ANY ALC).


On the K3, that is 4 bars with the 5th flickering, a little.  On the K4, 
that is 8 bars (to the 5), again just flickering.  On another brand, 
bring up the audio until the output power (any level) doesn't climb any 
more, then back it down to where the output JUST starts to fall ('close 
enough' but ask another station to watch your signal for purity).


Windows updates tend to muck with your settings, verify after each major 
update that they're what you wanted.  Take notes.


Also check that your coax is valid (not failing) with connectors snug.

The KPA500 Ser. No. between 1K & 2K or about 10 years old.  It has been in

I have not been able to do a full check yet because I changed computers 
sometime back and I no longer have a RS232 on the computer, so I ordered the

What I am seeing ( using FT8) is no output on 6M, on the HF bands the power 
increases in steps 50W then 60W then 70W and on the next cycle it will start at 
60W then 80W, 90W, etc.  In a few cycles it might get up to 500W, but it varies 
as to which HF band I'm on.
I'm thinking is it's microprocessor brain got scrambled with the RF.  I can't

If so, let me hear from you.

Re: [Elecraft] de W3TB and my KAT-500 question

[Rick Bates, nk7i]

Shutting down, as in power down?  Or cutting output (bad SWR)?

Check to make SURE that the K3 tuner is not online.  You do not want to 
cascade tuners (might be why it needs service?).
Check that you test into a dummy load, instead of the tuner/antenna.  
THAT is your baseline.


If it still doesn't produce 100 watts (when set for 100), into the dummy 
load, run through the calibration program (into the dummy load).


Please report your findings, to the list.

When disconnected, the K3 itself won't put out more than 35 watts without
shutting itself down.  Then it does fine when the KAT-500 is back in
service.  What's the good wisdom on what I need to do so that I can just
run the K3 at 100 watts while the tuner is away?  Yes, I can still get

Thread subject changed to reflect the actual topic.

It is the station owner that is responsible for lightning protection
(or other environmental risks); not Elecraft or most any product
vendor of any type.  To require more, would cost more (for the
hardware and for the liability risk that the company would have to
endure).

The area/s missed in the protective system design, can be demonstrated
by a nearby or direct hit (induced voltages and current can be almost
as damaging); as you already found (and it's EASY to miss an entry
point, no blame intended).

The ARRL has a good amount of simplified how-to in the book "Grounding
and Bonding" but several readings may still be needed for
understanding the content.  There are other good resources (Motorola
has one, so does the cell phone industry; each is excellent but best
used to induce sleep, they are intense and technical and reference
various applicable laws).

It's not all about lightning but static dissipation as an energy
source.  That static source may also be dust, wind, snow, or rain
(yes, water).  Diverting that charge OUTSIDE the building (shack) to
GROUND is the basic plan but it must also include EVERY entry point
(cable TV, phone, DSL, antenna, rotor, control cables for antennas,
mast, satellite dishes and tower).

Using several ground rods as part of a system is common BUT they must
all be bonded to each other AND to the one common safety ground of the
building (US and other countries require this, by law).  Use of water
pipes is no longer code, in the US (because PEX and PVC are common,
defeating ability to take to ground).

 From your description Jorge, it sounds like you did it correctly, but
missed an entry point.  Now you'll have to replace parts, sadly.

Let's limit any more, to Elecraft specific topics.  This one has
wandered well afield of Elecraft.

Re: [Elecraft] KAT500?

[Rick Bates, nk7i]

Eugene,

The KAT500 will work with almost any radio made in the last 40 years (or 
somewhat older), presuming the rig has I/O data available. If it doesn't 
read the band data from the radio ( on it's ACC port), there are still 
plenty of ways to allow it to do what it needs to do.  The utility is 
one feature that allows finer control or management.  But the KAT500 is 
serial port only for control purposes.  It doesn't have an ethernet or 
wifi system.


The following presumes that you have a serial (or other) port on the 
radio for it's control and this answer may be longer than you expect.


In the longer run (larger picture as your station develops), you'll want 
more than control of your KAT500.  You'll want to be able to log, manage 
mode changes, band/freq changes (rig control), turn your rotor, switch 
antenna ports on the rig or KAT500 and myriad assorted other necessary 
items.  Not all of the pieces are IP control but require USB or serial 
ports, like the KAT500.


You'll find that it's all much simpler to dedicate a computer (from 
Raspberry Pi, Arduino up to a full fledged top line gaming system) to 
manage the station tasks, hardware and software; even if you're sitting 
there able to mash buttons.  Simple just ROCKS and lowers the ... 
moments when things get busy or distracted and the brain makes mistakes 
(it protects you, a little).


I did that (ALL station elements managed) and it runs quite easily.  
Then I ran the station equally as well, by operating the computer that 
runs the station, remotely.  Two factors present a challenge, an 
adequate audio path for phone/cw, and latency (the time it takes to get 
from the radio to your ears, ad vice versa, no matter the path).  
(Remote can be across the room or anywhere with internet.)


I chose and use TeamViewer for computer control and Skype for audio.  
(Like most hams, I'm cheap and those apps are free and available on many 
platforms which gives a LOT of options from phone, tablet or another 
computer.)  Plus your contact log entries are (correctly) from the 
station, not where you happen to be. I've run my stations while 
traveling much of NA and HI while on road trips and it's still fun and a 
great way to keep in touch with the local gang.


Depending on the OS of your choice, there are many options to choose 
from.  Windows has FAR more options for the moment, the rig control app 
of your choice, a good logging program (integrated suites do much of 
these), KAT500 utility (check/verify readings and override choices if 
more than one antenna), amp control if you have one (KPA500 or KPA1500 
utility apps), rotor and antenna management (PSTrotator with the SteppIR 
functions) and if you want, an IP power switch for shutting it all down 
and/or rebooting. (A remote power on for the K3 or K4, when off, they 
are OFF.)


If you are a knob turner ham or a mouse clicker (or both), running the 
station is much easier when you integrate all of the aspects on one 
screen.  It allows quicker band changes (QSY and everything follows 
along) and a wealth of information on the screen, as well as the 
hardware displays.  You watch ONE place (the display), less movement 
required (except your eyes).


Wanna make a couple quick contacts from work during your lunch break or 
while visiting family for the holidays?  Now you know how.


Only have a tiny closet for the actual station hardware but no where to 
put the operating chair?  Now you can operate it remotely (be careful 
about heat removal in this case).


For now, you're working on the KAT500 with the utility; expand beyond 
that over time and integrate everything.  That means look at what you 
want the station to accomplish for you.  Wise choices now makes it 
simpler later as you integrate more.


And the answer to your question is yes, you'll want something to manage 
the KAT500 app, all the time.  But it must be via it's serial port.


Think bigger, go beyond.

Next question. If I want to control the KAT500 over ethernet, my understanding 
is I need to use the Remote server and client applications. However, it seems 
the remote client application seems to not have the full functionality of the 
KAT Utility program. Does anyone know if the full functionality of the Utility 
program can be available in a remote situation? Or is there where I veer into 
the note-red territory?

Re: [Elecraft] Very late to the party - computer rig control and sound card modes for K3

[Rick Bates, NK7I]

PLEASE PLEASE PLEASE make SURE that you do not allow OS sounds at ALL, 
since you're using the internal sound card.


There are MANY that already send beeps, tones, phone audio and more on 
the bands because they didn't get a sound card for the radio/s.  
(They're CHEAP, just get one that is known to work.)  Then they wonder 
why they don't get contacts with the digital mode they're using.

Dear Elecrafters,

Less than a month ago I asked a question about computer rig control, computer 
logging and sound interfaces for soundcard modes. Thanks to the people who took 
the time to reply and gave me helpful advice.

All is now connected in the EI5KI shack, I bought a refurbed Windows 10 laptop 
and set it up to talk my K3 using the USB to RS232 interface I'd had since I 
bought it with the K3. I now have communication between the rig and the logging 
software (Log4OM). I've also installed WSJT-X and I'm using FT8 and FT4 with 
some success. In the end I settled for a cable to break out the combined 
microphone/ headphone jack on the Laptop and two cables from that to the line 
in/line out on the K3. I did try a USB sound card (an Asus Xonar U5), but it 
won't talk to the laptop - this seems to be a known problem with Windows 10.

So, once again, thanks for the advice and encouragement.

Re: [Elecraft] question K3 digital duty cycle power FT8

[Rick Bates, NK7I]

13 seconds of transmit, 17 seconds of receive = 43% duty cycle.

I use (rarely) less than 100 watts, all the way up to band legal limit.  
With a K3, don't worry about it.  IF the cooling become inadequate due 
to local environment, it'll reduce output to protect itself.

Re: [Elecraft] Keying the K3s

[Rick Bates, NK7I]

Running exactly at 5.0 watts or 50 watts setting CAN cause a change in 
the TX GAIN setting on a K3(s).  That is the setting that can trigger 
the calibration algorithm; which if not connected to a dummy load, can 
be 'wrong' (causing problems).


The K4 has a menu item to en/disable changes in this setting, the K3(s) 
does not.


This is confirmed by Elecraft repair folks (on the groups.io list for 
the K3) and possibly here on qth.net.


Running at 4.9/5.1 or 49/51 watts output is HIGHLY recommended if that 
is the output neighborhood that is wanted.


Not every detail is in the manual (of which many updates have been made 
over the years) and not every firmware comment has been folded into the 
manual either.  So you look at the firmware comments AND the latest 
manual(s); then the email list_*S*_ for a complete answer.

I do drive an Alpha 8410 with my K3/10 -  and I've probably done so at 5W

Re: [Elecraft] KPA500 Voltage?

[Rick Bates, NK7I]

Too high at THEIR location.

Power company feeds, vary (not a lot but their load changes, they adjust).

House wiring varies and other devices on that circuit can cause other 
variations too.  Older homes (1950's and older) often have less capacity 
than newer homes (didn't need it then).  Today we use a LOT more energy 
than then; some house circuits are no longer 'adequate' (causing fires 
in some cases because folks abuse the wiring in ignorance).


Part of station set up and operations, is knowing what the circuit(s) of 
the house wiring, is connected to besides the station.  Fridge, washer, 
HVAC, electric oven shared with the station?


If you need one more tap to get within the right voltage window, use one 
more tap to achieve that.  If you change circuits, remeasure.  And if on 
the same circuit, maybe don't run the washing machine or oven at the 
same time as the amp. ;-)

Re: [Elecraft] KAT500 frequency memories question

[Rick Bates, NK7I]

It is, here.  The device being commented on, should be part of the 
header when a thread is started so folks can read it or skip it.


But it's MUCH nicer to have separate groups for each item.  One may not 
have a KX2, KAT500 or other Elecraft device and the often numerous and 
ponderously long threads can add up to a LOT of email to be deleted.


Being a member of the specific device lists, limits that and the email 
noise floor.  Being on a targeted list improves the chances of getting 
an accurate answer or solution.


Having a varied interest in many things, I get a low of 50 emails a day, 
sometimes peaking near 300 per day or more.  By limiting to the specific 
groups of interest I find I can manage it better and when it gets too 
noisy on a topic, I can drop out of that thread (if the list is on 
groups.io, most of mine are).  Thankfully the lists don't 'blow up' 
often so the daily average is under 100 most times.


Almost ALL of them are quickly deleted, less than 5% are answered and 
under 1% get saved for future reference (that's what archive diving is 
all about).

Re: [Elecraft] Kenwood MC-60 Mic with a K3?

Or leave everything as it was made, with no adapter, no modification; 
put a battery into the base of the MC-60A, turn the mic pre-amp on (in) 
and set the K3/K4 as needed with no bias.


The battery lasts for years; it's fast and simple to set up the radio or 
replace a battery.  And you never have to remember what was done to the 
mic (because nothing was). Simplest is often best.

If you have an MC-60 (not MC-60A), you can use it "as is".  The
only difference is that Elecraft and Kenwood reverse pins 5 and 6.
Pin 5 is +8V for Kenwood, Pin 6 is +5V for Elecraft.

If you have the "non 'A'" version of the MC-50 or MC-60, pins 5
and 6 are not used.  If you have the "A" versions pin 5 is used
to power the preamp in the base of the mic.  If you have the "A"
versions you will need to do one of the following:
   A) swap pins 5/6 in the Foster plug on one end of the coiled cord
   B) move the wire from pin 5 to pin 6 on the 8 pin jack where the
  coiled cord (PG-4C) connects on the base of the mic
   C) leave the preamplifier (mic amp) switch in the "out" position.

Re: [Elecraft] PayPal holding payment. (Follow up)

[Rick Bates, NK7I]

I use a major company (Visa/AmEx/MC) credit card as my PayPal go to 
'bank' for the PayPal account.


That way I get the ease and means to buy with PayPal (and not go get my 
wallet to dig out the card) when other means are not available (or 
shuffle funds to individuals as needed).  PayPal immediately hits the 
credit card but if there is a conflict I file the complaint with PayPal 
first, then immediately with the credit card company to refuse the charge.


This has worked very well the few times I had issues with an order(about 
once every 3-4 years).  The CC company does an immediate refund to my 
account, while investigating and I let the two of them duke it out.  The 
might (and lawyers) of the CC company is much more power than any 
individual can muster, PayPal usually 'expedites' their efforts to 
resolve the issue.  In the meantime, I have my spending power returned.


There is no hit to the credit rating, you are using the (local, state, 
Fed and international) law and the CC company policies, in your favor 
(PayPal can whine, but they have no power).


This method means the end buyer (us) has less to worry about.

PayPal will cry foul (but wait!  We'll fix this!) if you tell them 
you're refusing the charge.  They have no useful legal recourse if you 
made the charge in good faith and they won't take the time (spend money 
on lawyers) to argue. Their only recourse is to close your PayPal 
account, but that requires 'cause' (or they run afoul of the CC laws).


So don't tell them and be more careful when you use PayPal.  They are 
bound by the same CC laws but expect the buyer to be ignorant of that. 
Become an informed consumer; use the CC protection laws, in your favor 
when there is an issue.


Now if someone could explain (and make sense of) why it takes moments to 
make a charge, but 8-10 working days (weeks) to reverse that charge 
using the same network system; they'd be a hero.  It simply defies logic.

I agree Paypal offers no protection for the most blatantly fraudulent

Their own inaction under these circumstances almost makes them complicit in the

Re: [Elecraft] Elecraft Service

[Rick Bates, NK7I]

One simple question (with no implied or stated answer):

What would make a K3 a poor choice now, compared to other (used) brands?

It still works better than many (most) other brands, the only real risks 
are lack of parts when repairs are needed, as with any other brand and 
no more updates (which only a FEW brands offer at all, if ever).


With the jump to the K4, some K3 are available for sale and STILL sold 
within minutes to hours of posting.


The question is simple; the answer is personal and complex.

fixable except for a mysterious 2m SSB distortion issue in a IC-746Pro that 
haunted me from the first 2m SSB QSO I had with it to when I gave up on it 9yrs 
later.
   I was convinced that Elecraft was "THE ANSWER". How naïve I was. I expected a longer run for the 
K3 in years and the same with the K3s. Software upgradeable, never obsolete, a "new" radio every 
update! But technology marched on and "everyone" wanted the latest bells and whistles even if the 
bottom line performance improvements were minimal.
    How can we be to a point where a $4,000 radio should be considered a toss 
and replace? Do the K3 and K3s really contain components that are truly 
unobtainable? If that is the case, why would we expect the K4 to be any more 
maintainable? Did Icom, Kenwood and the rest stockpile more of the non-run of 
the mill components where they could be more maintained for a longer period of 
time?
    IF SOMEWHERE the parts are out there, it looks to me like an independent shop 
repairing Elecraft gear could fly. It sounds like depending upon Elecraft to keep us on 
the air is close to a thing of the past. Looking at my Elecraft "investments", 
much smaller than many, that is a very hard pill to swallow.

It does.  But you HAVE to remember to send a dit on each band change so

Re: [Elecraft] KPA500 faults

[Rick Bates, NK7I]

As I recall, when I got one of the first KPA500 kits available, it was 
also important to note the HV under load... I'd have to dig through 
ancient notes to see what the allowed window should be... or it may be 
in the manual.


That points to the usable power of the house supply circuit; more so in 
old wiring that might not be adequate for such a load (you don't share 
that circuit with a microwave oven).


Mine was borderline, sagged to the low end of that range, on the middle 
post (in a newish home).  When moved to another tap to increase the 
voltage; was still in the 'ok' range for unloaded voltage (it CAN be too 
high).


A little testing and experimentation is needed in setup of the amp; and 
at any new location.


Mine didn't fault in the sag, my goal was a cleaner output with the 
higher voltage while keeping in that window.

Hi Bill,

It MIGHT be faulting because the HV is too low. It's an un-regulated 
supply, so if line voltage is low, HV will be low. There's a jumper to 
re-tap the power transformer, accessible with the top off, details in 
the manual. We used to run into that when running two K3/KPA500 
stations on the same 2kVA Honda on county expeditions for 7QP and CQP.

Re: [Elecraft] Need help with kat500 utility

[Rick Bates, NK7I]

Let's start with the basic facts.

Rig --> amp --> KAT500 --> antenna/s (with the tuner blocking the amp 
key in while tuning).


1)  The KAT500 was working successfully 'for years' without issue.
2)  There was a sudden change in operation.

This doesn't necessarily mean it was the tuner; it more likely means 
that something in your antenna system has changed or failed (a rope or 
wire, the feed etc).  Start there (use an antenna analyzer to see what 
is different).  Take a look at ALL of that system (loose connector?).


Caps on either side, depends on the antenna load presented to the tuner; 
high or low impedance load (grossly simplified).


Key interrupt should be used for an amp, so you don't put too high a 
stress (mostly on the amp) during the tuning process, causing damage.


Likewise attenuator kicks in when you overdrive the tuner input, prior 
to a fault if it doesn't change.


At least this is my understanding, subject to confirmation/denial.

I had been using my kat500 for years and all of a sudden low SWR  matches

I found by checking "caps on the Ant side"  Ii could get a match in manual

  I wonder if that had been checked and all of a sudden it stopped being

Also I wonder if the"amp key interrupt "  was ever set properly.
How should it be set with a KPA500 amplifier all cabled up.
I did not see a simple explanation what these kat500 setting are for.

Any help would be appreciated.  I think I am going for a walk

Which antenna port on the KPA1500 are you using? Port 2 is disconnected 
at power off.


That's one small nit with the amp, the antenna switch and tuner are on 
the same power source as the amp; all or nothing.  It takes getting used 
to, after being familiar with the KPA500/KAT500 combo.

Re: [Elecraft] K3 Auto ATU Problem

[Rick Bates, NK7I]

The KAT3, KAT500, KPA1500 tuners, all have the same feature.  I have all 
three.


If you want a finer (lower SWR) value, within a few seconds of the first 
tuning cycle stopping, start the sequence a second time and the tuner 
will cycle through ALL possible settings to attempt a lower match.  It 
may/not make a difference.


I would also, at this point, seek out an antenna analyzer to see what 
data could be gleaned from that; perhaps a cable, connector or other 
antenna system element (anything beyond the tuner, even IN the radio) is 
no longer valid.  Tuning into a KNOWN 50 ohm dummy load may show 
something interesting as well.


Again, setting CONFIG | TUN to 10 (watts), should help resolve your 
issue, 5 watts is a touch low.  If it does not, you may have a failed 
component (or relay) in the tuner.


If you can, try to eliminate the possibilities (antenna, feed, 
connectors) to find out what failed/changed; narrow the search.  (Does 
another radio tune the antenna easily, EVERY time?)

hang up on a less than optimal solution

Re: [Elecraft] Legal Limit With FT8

[Rick Bates, NK7I]

On phone or CW, it's a dog fight and power (and antenna gain) often 
reigns supreme.  That's the reality.  Get heard, get worked, get out.  
The JT modes bring something new to the playing field; making it more 
'level'.


For many, it's not about the distance or miles/km per watt.  That is 
determined by the magic of radio conditions.  QRP into a light bulb 
filament (not LED), may work stations during the really good cycle peaks 
while in the doldrums one must use a lot more to make the contact.


As Jim rightly says; it's ALL about noise, but keeping your local noises 
to a minimum is only half the equation.  Expanding what he says, when it 
comes to working DXpeditions (taking the latest groups in AF as an 
example), the antennas are not optimal (because they are hauled in/out, 
not on 30 meter high towers with proper grounding, not a permanent 
installation but lashed up); their local site is rarely optimally placed 
(a hotel or beach), the noise floors are frequently very high 
(thunderstorms add more exciting noise) and the power grid is also noisy 
(and intermittent) in some areas. Their output levels are variable due 
to ability or local laws, often not 'generous'.


The end result is that the calling station, generally has ZERO clue 
about conditions at the other end.  One can watch the DX to see the 
reports given and get a sense of their hearing ability (or lack) for 
known big guns being worked; but until the actual contact is made and a 
real report (life isn't always 59) given, one doesn't really KNOW that 
the power was excessive; then it's over.  What YOU hear is not what THEY 
hear; compare equally built stations but pay attention to the NOISE floors.


In some cases, one must surf the waves of QSB too; timing is critical in 
any mode.


Sadly, this is true even on permanent stations, i.e. one on Guam that 
transmits a GREAT 100 watt signal but the noise floor is so high that 
those calling MUST run much higher power to be heard.  Often, it's not 
possible.


However, JT modes also allow those with less than optimal (flea power, 
string antennas) stations to participate more often.  Perhaps not to 
work the rarest of DX, but they're 'in the game' enjoying the hobby.  
That's a HUGE benefit.


Rarely, the reverse is true.  Working the Antarctic stations with their 
noise floor at MDS, their reports are often better than most stations 
calling (I was so shocked that it worked with a meager wire antenna and 
100 watts on 60M [legal EIRP limit in the US], I tried for an 'insurance 
dupe' at half the power just to verify, got it too).  In that case, they 
had to overcome MY local noise, which is pretty good in the rural zone 
I'm in (the same worked on CW too and they weren't loud).  [K3's at both 
ends, HAD to help at least a little.  ;-) ]


Don't sweat the output power of others but pay attention to your 
station.  High output doesn't help work stations faster in JT modes 
(which can even be set to ignore loud stations in DX mode) and it 
doesn't usually cause an issue IF it's a cleanly transmitting station 
(KEY POINT), even when on the same tones as others (I've seen two 
station on exactly the same tones get decoded, one +4 and the other -18 
dB, the JT modes are magical).


My general rule is to base my output power on the signal level I 
receive, with a sense of their local conditions (based on their 
reports).  If that doesn't work, double the output power (add 3 dB) and 
try again (repeat as needed).  Generally, that works out but not always 
if the DX is in a noisy place.


In a perfect world of no noise, we could all work each other at QRPp 
levels.  Reality is much harsher.


Lower YOUR noise floor and keep YOUR station clean to cause no harm; let 
the other stations do the same.

Rick NK7I

Re: [Elecraft] HOA Crap

[Rick Bates, NK7I]

No!

Rent a station is NOT ham radio.  Argue all you want; but ham radio is 
about RADIO, even if it's just owning and using an HT because that's all 
you can manage.


You may as well log cell or Skype phone calls or EchoLink contacts (or 
IRLP, DMR, DStar etc) as use remote stations that are not yours; they 
have equal merit; none, zilch, nada, nil.  Only a few even have a radio 
involved; the rest is internet links; not ham radio.


EVERY entry in my log is from MY gear, a station assembled by ME 
(sometime with help building etc), a result of MY best efforts at THAT 
point in time.  It's a matter of pride and is a moral imperative to my 
standards.  Yes, it means I don't make EVERY contact or work every DX 
when I want; I have to wait for propagation, then hope I've done 
enough.  Yes, I've put money into equipment to own, use and maintain; 
not someone else's pocket to rent.  But I EARNED every log entry.


I pity you some; you've lost your compass.  Yes, you can get DXCC in an 
afternoon, moving sites to best apply propagation <>.  It's NOT 
your station, it's not worthy of your log; it has no value, because you 
purchased your log and awards instead of investing your time and 
efforts. It's your ego being stroked by your wallet.


Ditto using remote receivers to augment your own; your station can or 
cannot; it's THAT simple.


You have ZERO emergency preparedness without a radio; one of the tenets 
of ham radio.  You can't be prepared if you don't own a radio; if the 
systems are down, you have nothing.  An HT can at least saturate the 
neighborhood to check on others around you.


If you are so HOA bound that nothing outside can grow as an antenna (has 
NEVER been totally exclusive; stealthy has a market); build a club 
station where you can; drive there to operate it and log from that.  If 
it is an emergency and there IS still access, then use the remote if you 
have nothing else.  At least own and learn to use a portable radio (KX3, 
dual band HT, SOMETHING).


Yes, I operate a station remotely; MINE.  And if done well, no one knows 
where you really are at the time of the contact.


But you won't ever sell me that not owning a radio at all and to rent 
and operate remotely is even CLOSE to being a ham.  For pity's sake, 
hand the man an HT!


Harsh, perhaps.  But it's also one reason to escape the blasted HOA 
world too to make your own decisions. HOA is an infestation, a virus 
that allows others to make choices for you, even if you don't like their 
decisions.

Re: [Elecraft] Speaker upgrade

[Rick Bates, NK7I]

Regardless of radio, my go to is the black Motorola mobile speakers (~5" 
square, with mounts).  Already shaped for communications audio (chopped 
lows, peaked mids and some highs) by design, they sound awesome on the 
K3 *once you find a matching output pair* (they can vary in output by 
several dB).  Estate sales, swap meets and radio shop closures are prime 
spots to find them; often $10 each (oh heck yeah, snag it and bag it!).


Also, if you find them, the old Radio Shack speaker cubes (about 2" 
cubed) have very clear communication audio and work great in a mobile 
environment.  Before RS went out of business the price was jacked up to 
about $60 (from $10) so swap meet prices may vary.


I (almost) never use any internal speaker since they are not usually 
more than a basic add on, or have to be cranked up so much to be useful 
that they don't last long (and are mono with dual receivers).


You might check to see what Elecraft offers for speakers to match your 
radio esthetics should your budget allow it.

microphone (web cam or often built into a laptop) to be accessed EVER 
(by disabling it AND reducing the level to zero), lest it find a path 
into the transmitter.  Checking after each update is required; levels 
and setting CAN change then (check 'listen' tabs  to deny as well).


That is the same issue as those who choose a mic input for (computer 
audio) digital TX, yet fail to disconnect the mic during digital 
transmitting, so both go live and unintended station sounds are 
transmitted with the wanted digital tones.  (head slap!)


Again, a rig costs hundreds plus, a computer (except Pi) does also; yet 
there is resistance to adding a $20 item to make legality simpler to 
meet... not a significant price.


Phil, you're correct in that it merits a question on the test; it's that 
common an error.  (No, I won't poke the bear, except to get a better 
photo, hi  and only from a safe distance).

Re: [Elecraft] External sound card advice needed to attach to K3

[Rick Bates, NK7I]

You're making fun of care and caution?

Mistakes will happen (forgetting to turn VOX off when done with the QSO; 
bumping the key, the snoring cat laying on the microphone switch) but 
that is not the same level of mistake as transmitting ambient noise, 
operating system sounds (of any type) or similar.


We are all liable for what is produced by our stations; we should take 
that seriously and do our best to manage them.  It's been clear that 
there are many that don't as often found on the bands.

Re: [Elecraft] External sound card advice needed to attach to K3

[Rick Bates, NK7I]

I disagree, most users are not adept at the trivia in the drivers, so 
the chances of errant audio (monitor the microphone locally check mark) 
increases the risk of transmitting 'garbage'.


The user also loses the benefits provided by the OS sounds (as said in 
another email here on the list).


The average ham radio costs at least hundreds of dollars to buy, an 
adequate sound card is under $10-20.  It's not an economic strain.  The 
cost of wire for a simple antenna, costs much more.


Many newer radios come with a sound device built in; just use that and 
let the OS do things as designed for audio.

Re: [Elecraft] External sound card advice needed to attach to K3

[Rick Bates, NK7I]

HNY Phil,

While I'm not an attorney, I've read the rules (subject to 
interpretation of course).  Transmission of music is specifically 
unlawful.  (What is defined as music these days, also subject to 
interpretation, hi hi.)


Defined in the simplest of terms, any sound transmitted other than for 
the purposes of communication (voice, tones for digital) is illegal.


This includes background music in the same room as the microphone 
(though generally ignored as part of the environment, in the US; same as 
telephone 'hold' music in an autopatch; traffic noise etc.) and 
certainly includes the 'musical' sounds from most OS (they offer no 
communication).


Which, to me, means the sounds from an OS are unlawful to transmit.  If 
the incidental OS sound is spoken ("You have mail"), that isn't legal in 
the digital, non-phone) portions of the bands.  At the very least, they 
use more spectrum than necessary (i.e. 3 KHz bandwidth in an area for 
FT8, which uses ~60 Hz bandwidth per user) and offer nothing for 
communication.


Considering the general apathy of the FCC lately (US of course), I'm not 
surprised that this has never been tested by citation.  I'd much rather 
err on the side of caution.  Turning off the OS sounds is not a complete 
solution.


Using a sound card, specific and limited to the radio use, is a vast 
improvement over using the OS sounds device to maintain legality.

Please explain your comment "all illegal" concerning "operating system

"operating system sounds".

Re: [Elecraft] K3 Tx Spurious on Specific Frequencies on 160/80/40

[Rick Bates, NK7I]

I don't have an answer, I have no test gear that would even allow a look 
(other than another radio).  But I'm curious how you're measuring and 
observing (not doubting) these results.


Except for the reports seen on the air to validate your observations; if 
the radio change barely affects the results and the condition does not, 
it's either a failure of both radios or the testing environment (i.e. 
transmitting into the same antenna).


What happens with changes in power output, different (dummy) loads?  
Then the eternal question; since this hasn't been noted before at your 
station; what else is different or has changed?  Have you tightened your 
antenna connectors lately?

In general I've found the spurious performance of the K3 to be pretty good,
but I've noticed something today that I thought it would be worth asking
more widely if anyone else has seen and fixed.

  


I was calling CQ on 40m around 7014 kHz and I noted that several skimmers
also reported me weakly on c. 600 Hz either side of this frequency.
Sometimes skimmers have bad spurious responses, but seeing this on more than
one skimmer caused me to look more closely at my transmit spectrum. I
discovered that - particularly on 40m - there were specific frequency ranges
where a pair of sidebands appeared that move at 150% of the change in
carrier frequency. So on 7012 kHz they are at roughly +/- 500 Hz, at 7011
kHz they are at roughly +/- 1 kHz, at 7010 kHz they are at roughly +/- 1.5
kHz. They cross over with the carrier just below 7013 kHz.

  


Similar patterns recur in other parts of 40m, but they are strongest near
the bottom of the band. There are dramatic step changes in the level of the
spuria at the boundaries between synthesiser segments - So I see spurii from
7000-7004, none from 7004-7009, spurii 7009 -7015, etc. They peak in
strength when they are about +/- 500 Hz from the carrier, but drop
significantly in level as you get further from the carrier.

  


The level of these spurii is what was concerning - at their worst they were
less than 30dB down on the transmit signal. They grow somewhat non-linearly
with power. At 5W they are -40dBc, at 12W they are -32dBc, at 13W they are
-35dBc and at 100W they are a little less than -30dBc. I can see the same
style of spuria in some segments on 80m and 160m - but at lower levels.

  


I assumed this was a fault with that specific radio - and in some ways it is
- but the same spurii are present on both K3s that I have here - but on the
second radio they are no worse than -45dBc.

  


I've disconnected everything connected externally from the radio, tried
different power supplies, and recalibrated the synthesiser and Tx gain with
no significant change.

  


Both radios have the original synthesisers - not the KSYN3A.

  


Any leads from anyone on this one?

Re: [Elecraft] External sound card advice needed to attach to K3

[Rick Bates, NK7I]

Precisely why (since MS can foul up audio settings routinely on any 
random update) it's a bad idea.  Leaving one small check mark in a lower 
level driver setting (looping/routing audio) that leaves a mic hot is 
but one example.  There are  too  many ways to make an error.  Using the 
computer sound card on a radio is not 'set and forget'.


We still have a large base of folks that don't get what is required to 
operate a clean (legal) station; we all learn as we go.  Setting 
boundaries is part of that edcucation (OS stays in OS, radio stays in 
radio).


Turning off the OS sounds, one would also lose features that the OS and 
apps that are useful (like JTAlert "DX" announcements, Zoom/Skype 
audio).  The small cost of a sound device (or second sound card) for the 
radio(s) is certainly worth the gains and lowering of the risks.

For getting started, there is nothing 'wrong' about the SignaLink USB 
but there are better devices out there (less noise, better sensitivity, 
flatter response).  There are also many mods for it to make improvements.


So for now, use what you have and when it you can (as with anything

As long as you are not looking for voice DVK support (planning to loop

Re: [Elecraft] K3, KAT500, KAP500

[Rick Bates, NK7I]

You can put (either) the KPA or the K3 on the KAT500, it can take the 
weight.  When I used that combo, the amp sat on the tuner, no issues.


However, it's in your better interest to allow nothing atop the K3 AND 
the KPA to optimize cooling.


If you MUST stack them, shim (along the side edges) them to allow for 3+ 
inches of clearance to allow for heat dissipation (venting for the 
fans).  Again, that's not the best situation and should be avoided.  (K3 
on the bottom for easy control access, SHIM, KAT, KPA)


As said; you WILL have a mess of cables to address as well, RF, ACC, 
serial lines, power...  confining that to a small space rarely goes well 
(pull on one, five more follow).


I'd suggest serious thought to come up with a better arrangement.  If 
you use computer control and logging, the KPA/KAT combination don't have 
to be visible (just allow for cooling), and within no more than 6' of 
ACC cable away from the K3...  The computer can change modes, trigger 
tuning etc. via the utility apps (saves a long reach too).

Re: [Elecraft] K4 Radio Update

[Rick Bates, NK7I]

Usually any kernel update has to do with security issues (that's a very 
broad stroke) so freezing it would leave security gaps or known issues.


Then there are files that constantly seem to update (i.e. the time zone 
files are a constant state of update; who knew it was so tough to figure 
zone changes?).


And there may be improved drivers for the hardware, which may break 
things relying on eccentricities of the old driver...  Or drivers for 
new hardware since the last release instead of the generic driver that 
was used.


I randomly update my linux machines, no pattern at all but months apart 
is a fair guess.  They don't have many ports or services available so 
while they're still attacked, so far, there haven't been any successful 
break ins.  I also split the duties to various computers around the 
house (the router knows all and puts one linux box in the DMZ and it's 
secure enough to handle it).  Without knowing what I did, the end user 
doesn't have a clue what machine or OS I'm using.


Sometimes even the version (and support) have had a major update, which 
may change a lot of things in one pass. That's not always good.


Often the audio breaks because the app used to manipulate or process the 
audio is deprecated; so scripts or similar that call the apps must be 
adapted...


It's an evolving OS as any other, which means changes.

I'm sure Elecraft will stay on top of it.  Keep the faith.  Their name 
and rep is on the line and they treat things in that manner.

Re: [Elecraft] KAT500 lost serial comms - try factory defaults?

[Rick Bates, NK7I]

Frank,

I would start with a complete power removal (not just off) to the KAT500 
and the computer (unplugged from power).  Then go have a cuppa.  When 
you get back, plug the power in and restart it and test.


I have found that some devices (more in the USB realm) occasionally 
'stick' when exposed to RF and that a long power removal is the only 
cure.  If it's a frequent event, you have an RFI issue to deal with 
(better grounding and bonding is the first place to start for that).

Hi all,

I’ve used my KAT500 with pleasure for many years, but recently a problem has 
arisen: I’ve lost the serial communication feature. I’ve already swapped the 
KXUSB cable with another one (home-brew) so I’m pretty sure it’s not the KXUSB 
that’s gone kaput. And the PC is doing USB comms fine (e.g. the USB interfaces 
to my K3), so I guess it’s not the PC or the USB port either.

I’m contemplating trying a KAT500 factory reset. But two questions arise:
1. Can I do a factory reset without having the serial comms working (so: can I 
do a factory reset other than from within the KAT500 Utility)?
2. What antennas are enabled after a factory reset?

(Question 2 is because I have multiple antennas connected to the KAT500, and if 
the factory defaults would be that only ANT1 would be enabled, I would lose 
functionality until I’ve got the KAT500 repaired…)

Hope the collective wisdom of the group can help me out.

Re: [Elecraft] KX2 & FT8

[Rick Bates, NK7I]

Rich,

You WANT to change what Windows does because a generation ago, to allow 
their server software to function, they increased the error gap in the 
NTP system.  It allows WAY too much drift and they've never cleaned that 
up (because most users don't care).


I use and suggest Meinberg; which can replace the Windows NTP service.  
It's free and keeps my computers within .03 seconds to standard (on very 
slow Internet) without requiring high overhead (it just works and well).

Re: [Elecraft] Firmware development

[Rick Bates, NK7I]

Well that IS rather condescending.

I would take a different view, that MOST of the hams using Elecraft use 
MOST of the features on a regular basis but because the features are 
designed well, the user doesn't NEED to fiddle about (or understand the 
precise ways they work).  One of the benchmarks of a good UI is that 
most of it is set and forget.  Elecraft: PASS


With the support group, the manual and the Cady book; there is ample 
opportunity to learn some of the nuts and bolts for those who want to 
know.  Once set to operate in the fashion that the user prefers; the 
radio (with all the features) is simply used.  If one doesn't understand 
a function or wishes to learn a better use of a feature, they can read 
or just ask (or watch a video if that is how they best learn).


No one is born with all knowledge and I won't be disparaging to new 
hams; some of them blow right through all the exams in one sitting going 
from nothing to the highest license. They may not have experience yet, 
but clearly they're not idiots as you imply.  (Sadly, some are, even 
after decades of opportunity to learn better.)  It is the job of every 
ham, to teach them how to be better, to pass knowledge along.


Some people LIKE making adjustments and learning the deep secrets of any 
device; others adjust according to their needs and a few just leave most 
of the settings as stock and yet none of them are wrong.


Elecraft radios are no more complex than other radios but the simpler 
front panel UI (based on USING the radio, not fiddling with it) hides it 
a lot more than many other brands.  Then add that Elecraft designers 
actually USE the radios in all things ham radio; they understand what is 
needed for the 'average' ham, the DXer and the contester no matter what 
mode they choose. Kencomsu may, we never know and hear only crickets 
from them.


The K4 won't be much different; simple up front with the bulk of the 
used (but no need to be in your face) features accessible with the menu 
UI.  Certainly it's a better platform for future growth with refinements 
unavailable when the earlier models were designed; but that's splitting 
hairs that only an extreme user (contesting, DXing) would require.  It 
will be a solid, dependable radio, no matter how the ham chooses to use 
it; with growth potential unavailable from almost any other brand.


Name any other company that gives you FREE firmware updates in real time 
(not months later like Icom or never like most others) until the issues 
are resolved to the user satisfaction; or that ADD features previously 
unavailable. Or offer hardware updates or refinements, in part because 
the radios are designed to be modular and upgradeable as new devices are 
available.  Or board level support.  


No, I won't disparage or belittle any of the Elecraft line; the UI makes 
it all available (mostly set and forget); you get to talk directly with 
the designers and owners of the company and they do more than any other 
company to make things 'right' in the eyes of the customer/user; not 
just give cookie cutter designs and answers then move on with no help 
provided.


And the product line just works better, hearing ability is among the 
very elite and transmitters are cleaner on the air than most of the 
other brands.


If a user is constantly fiddling about with the controls; it's because 
they either want to or don't understand their proper use and should ask 
questions.  Set and forget is an asset.  Once set, the complexity hidden 
within the UI is one of the strong points, because it doesn't require an 
EE and operation becomes simple allowing the user to simply use and 
enjoy the radio.


If the user has not looked into all the settings, perhaps it's because 
they haven't needed to do so.  That's a telltale mark of a good product 
(although the ham SHOULD learn more about what tool/s they're using, in 
my opinion).


Maybe you haven't dived into the depths, because you haven't needed to 
or other reasons; but I wouldn't group all users in that category.  Each 
user has an level of understanding and ability; no two are exactly the 
same; no two stations are precisely alike.


When I first get any piece of gear, I go through every setting, making 
sure I understand it's use (adjust if needed); then I stop being 
concerned about the vast array of choices and just use the radio.  I may 
go back for refined adjustments, but that's not very often.  I suspect 
most hams are similar to that method.  If it's been a while, the manual, 
Cady book and group can be used (in that order) to find the proper control.


By design, Elecraft radios can be used by a wide range of hams from 
basic noob to EE+ education; from ragchewers to extreme use>; they've hit the mark.


They allow the hams to rise to higher level of understanding, competence 
and ability because of the quality; with some help from the manual, user 
groups, Cady book and DIRECT contact.  VERY few companies are at that 
level, ot

Re: [Elecraft] KAT500 Anomalies

[Rick Bates, NK7I]

The short answer is you 'teach' the tuner on each 'bin' frequency what 
the settings are for a good match (with each antenna, each on it's own 
antenna port).  Then you put the tuner into manual mode; which still 
adjusts the matching values as the frequency changes BUT disables the 
retune feature.  You DO need to pay attention to SWR, that should be 
second nature anyway.


Every time you 'teach' a value into the bin (one per antenna port), it 
overwrites the previous value(s) so no, you won't run out of memory.


One thing I would do is check the tuner component values from your 
baseline (dry, sunny day) to the current values, it's possible that 
something is changing on the antenna more than usual (ladder/window line 
DOES change a little when wet or windy and near other 'things').  If the 
changes are small, you'll be fine.  Any major shift in values (or SWR) 
should be evaluated for cause (broken wire opens when windy?).


I suggest that you limit the amount of feedline movement, if possible (I 
tied mine with a cord, to the fence, then it ran to the shack, slightly 
tensioned just enough to compensate for tree movement, not free sway).  
That reduces the seasonal affects.


You could also compare un-tuned SWR to see if there is a radical change, 
but SWR is not the entire story of the load (it's a composite measurement).


Of course, make sure that your matching device (balun has variable 
meanings making that name, useless) has tight, clean weather resistant 
connections and isn't bothered by weather or seasonal debris (leaves).


I came across similar changes when I used a 375' center fed dipole (80M 
EDZ) at only 35' (oaks didn't grow much taller), window line fed into a 
4:1 common mode choke transformer and a SHORT piece of coax into the 
shack.  It worked well on all bands, I managed over 200 countries 
despite the local noises (noise floor ~-80 dBm).  Now I use a resonant 
antenna (80-6M plus one on 160M) which is MUCH simpler (but expensive) 
with a noise floor typically in the -120 dBm range (ah, quiet!  I moved 
away from the noise).

I've been using the KPA/KAT500 Combo for a bit over a year, and while there

etc.) so I often return to the same frequency on each band.

  


Today, running 50 watts in Winlink VARA HF mode, it had problems staying
matched on 80 meters.  It would try to rematch on each transmit cycle.

  


As a result, the cycles were incomplete and data transfer was erratic.

  


My question is, how many memory settings can it hold in memory, per band?
My antenna is fed with ladder line (yes, I have a balun, etc and it's been
fine for well over a year).  It's possible that the system will tune
slightly different now and then due to the ladderline blowing around (in
contact with tree leaves, let's say).  Am I using up so many memory slots
after this time that it is running out of space?

  


Thinking that might be a possibility, I reloaded a config from about 6
months back which would not have seen as many frequencies used.  I have also
experimented with the MTA commands.  At this point, it seems stable.

  


I've always been a bit confused by the "Teach it in Auto Mode, but Operate
in Manual Mode" suggestion I've heard from time to time.  As received, the
"Memory Recall Tune on QSY" defaults to ON for both modes.

  


I'd appreciate any insight from KAT users.

Re: [Elecraft] Antennas and Output Power - KPA-1500

[Rick Bates, NK7I]

This happens due to heating of the finals (network); typically 1500 
watts when cold (15-25C in my shack), drops to 1400 watts once warmed up 
(50-60C).  One can either adjust as needed or just accept 1500 cold and 
the drop (much less than one dB); but of course one should pay attention 
in all cases, should the limit exceed the permitted levels.


True gain values should include the temp of the amp; it matters.

90% of the time, when I use the amp, I'll run <1200 watts out, even 
though there is already plenty of headroom in the amp.  It's rare that 
the few hundred more watts makes any real difference (but it's nice to 
have!).


Now that winter is starting (North Idaho), it also takes the chill off 
the shack!

Re: [Elecraft] extension of the length of the K3/KPA acc cable

[Rick Bates, NK7I]

In a post long ago, 2 meters was posted by Elecraft, as the max end-end 
length of the ACC cabling (two sections of stock cable).  Cabling longer 
than that /MAY /affect the signal timing, causing errors (their words).  
I ran my temporary station that way (for a couple years) until I got the 
new shack room built and had no issues with cabling.


The cost of the proper cable from Elecraft is reasonable or there are 
other sources (at your own risk).  You bought a Ferrari of a radio, are 
you going to cripple it with questionable tires?  Don't cheap out, do it 
right.


I also agree, the N6TV boxes (and cables) simplify the wiring (not 
neaten to any great extent but it helps, it's great but not miraculous 
:-P) .  If you go that route, Bob will work with you for the proper 
pieces based on your needs.  Neatness helps minimize noise and other 
issues too.

Re: [Elecraft] K4 Remote Question

[Rick Bates, NK7I]

I've tried that (with 10 dB sticks on my wifi cameras) and it didn't 
really help.  That router already had high gain antennas (not the mesh 
style, they're apparently only available with internal antennas, sadly).


To 'translate' from a wired only device into wifi, an extender (with 
it's own router) can help, but as I've said is not the cure.  A pure 
wire to wifi dongle may (then the device is just another network user 
for the router to figure out).


My OpenSpot (original) is one of the devices wired to a node, the IRLP 
computer is another (each node has two ports, one of which can be 
connected to a switch too if you need more ports).  That way the mesh 
just handles the data without extender conflicts.


What shocks me the most is the sheer volume of 'toys' connected at any 
given moment, often upwards of 30 and I live alone!  Cameras, printers, 
computers, bluray, weather station, smart tv... it adds up very quickly.

Re: [Elecraft] KPA-1500 SWR fault above 700-800 watts on 160m

[Rick Bates, NK7I]

Being able to use a  without reading the manual is 
actually one of my personal tests of the user interface.  Jump in, see 
how it plays and what is presented to make changes if needed.


The K3 easily passes that test (former Kenwood user; Elecraft is similar 
in format), HOWEVER that is on the surface only.  One must read through 
the manual (a few times preferably) to get into the menu settings (only 
one layer deep) and the reasons for them, when to apply them.  An annual 
or topical review can be done in personal down time, to keep the meat 
memory cells active.  And even then, something new may 'appear' in the 
text and learning happens.


Then for reading dessert, read the firmware update statements as a few 
things are added and others change slightly over time since the manual 
was created.


I also have a 7300 (for the RV) and it's not as UI friendly to me but is 
a convoluted series of menus to alter what should be a simple change; so 
it's what one is used to seeing, in part.  Some of that is 
cross-cultural phrasing, some of it, is a lesser UI (in my opinion).

Re: [Elecraft] Inverted L for 160 meters

[Rick Bates, NK7I]

For the record, I agree but as I made no series of qualifying tests; all 
I was able to state in my previous comments was that the inverted L was 
more efficient (heard by more) and I heard better when I went vertical.


Both of which can be my change in location; this locale is loads 
quieter, one of the points I reviewed before purchase.  Although moving 
800 miles north in NA rarely helps propagation (I didn't move here for 
the fast internet or easy prop).  I can state that I have another 80 or 
so ATNO since the move (because I can HEAR now!); sitting at 304 worked 
(but I really have to work on getting more QSL cards).


What I have now works ; I mostly work what I hear (and with a K3, 
that ain't bad).  Will it work better with stacked arrays and/or taller 
towers?  We'll never know.  ;-)   Soon I'll be down to one antenna per 
band (total 2 for HF).  While that makes 'single point failure' 
possible, I like simple... and I have other endeavors should the 
antenna/s fail.

Bingo!  We would all like to build the "perfect" antenna for each band and
each intended usage, but more often than not, there are limitations.

In my case, a vertical of any significance would not be permitted by HOA
rules (visible from street), nor would installation of a suitable radial
system be possible due to septic drain field and other considerations - both
physical and aesthetic.

So we do what we can and try to maximize the performance thereof.

Done.

Re: [Elecraft] Inverted L for 160 meters

[Rick Bates, NK7I]

I will interject here that when I lived in Mordor, er, CA, I also used a 
low (35' max height) EDZ (370', window line fed dipole).  I was able to 
work 200+ countries on all bands (I used a J pole on 6M) within an HOA 
environment (I put it up on a weekday when no one was home, it was 
'invisible').  Then I came to my senses and left the state.


For the first two years here, I used an 80M Sloper (was originally a 
dipole, but a branch took out one end, in the middle of winter snow) and 
a 160M Inverted L which I used on all other bands (except 6M).  In many 
ways, that was better than the EDZ (not enough trees to reuse that) but 
mostly due to the lower noise floor (dropped by ~40 dB in the move).


Now I use a SteppIR DB 36/80 at 60' (and the L on 160M) and it easily 
blows everything I've used out of the water, always in resonance too.  
Not only does it hear better (by nulling out noises, favoring the 
intended direction) it provides gain as well.  A HUGE difference to the 
untuned (but matched) Inverted L (what was unheard, is now workable).  
(Adding a proper grounding system also lowered the noise floor another 
20 dB on average; the house Ufer ground, while legal, was not 
sufficient.  At many times, the floor is at the MDS of the K3.)


The Inverted L at 500 watts out, talked better than it could hear (on 
the K3), frustrating everyone, proving that mismatch losses cost in both 
directions (and costing me a lot of DX).  After installing a proper 
grounding system AND bonding EVERYTHING; the next challenge is to lower 
the noise floor further (remove or reduce all noise sources).  I can now 
hear a little more than I can work (the 'other' side has noise to deal 
with) but will add an array for low band RX.


So you're both right, everyone is limited by what is available on the 
property and budget; I've used all the antennas mentioned in this 
thread.  And that, is the rest of the story (and even in the low range 
of the solar cycle, I have added some ATNO and numerous band slots).


Jim, I'd submit that not only is 160M more challenging on the left 
coast, but 6M is worse since it tends to be N/S much of the time and 
even the coastline leans left so not many stations are south. ;-P   6M 
like 160, also 'spotlights' but in pinpoints.  I have managed DXCC on 
160M since the move, 6M is still a greater challenge (up to 6 so far, 
it's a start).


I'm pleased your place has survived the fires (please do your PRC 4291 
'homework' to continue that good fortune).

E-W for 40m, Increasing numbers of lobes as we go up to 6 meters and thusly

How does that compare to your Inverted-L? (Serious question ...)

Re: [Elecraft] KX3 radio settings for WSJT-X

[Rick Bates, NK7I]

That is clearly a case of RFI; the USB connection is 'sensitive' at that 
frequency range.


Your clue is:  "
then settle down quietly to about 100W.
2.  Around the same time Windows reports "USB device not recognized" and 
the mouse cursor disappears.  "


If it doesn't happen at low wattage but does at higher is your hint; 
you're getting RF back into the shack, which is never a good thing.


Presuming that ALL your equipment is properly bonded AND grounded (not 
the same thing), adding some ferrite to the cabling (begin with the USB 
cable) would be a good place to start.


If you are not completely bonded and grounded, start there first (it can 
also lower the noise floor so you can hear better too).

[Elecraft] Remote station ops

[Rick Bates, NK7I]

Not to allow thread hijacking (now renamed at least);

One of my goals is to allow each component of the station to be 
manageable by a computer, in part for the purposes of operation when I 
travel.  Once that goal has been met (99% successful, a couple things 
are 'better' with eyes on), using TeamViewer (and Skype for phone modes) 
is simple.


I've done this for years, successfully but it requires solid 3G or 
better at the remote end, which is often a far greater challenge.

I'm not saying text-to-CW is the only way to reap the benefit of modern

People only interested in a contact will probably always prefer
WSJT-X/FT8 because it does that very well, but both contesting and rag

Well, the fact is that the coding and processing behind modes like FT8
doesn't have to be as rigid as is implemented in WSJT-X.  It only
requires that information be sent and received in time frames, and

those

time frames are simply a function of three variables ... bandwidth,
rate, and number of characters in the message frame.  It would be
possible to change any of those, such as widening the bandwidth to
increase the number of characters for the same time frame.

It would also be possible to send text but have it converted to CW on
the other end.  Or even to key CW that gets converted to text before
transmission ... i.e., CW to CW except with significantly better S/N
performance.  If the user was willing to live with a narrow bandwidth
single conversation format, clock synchronization isn't even really
needed.   And if we were willing to live with a single conversation
format, there would be no point in cramming everyone into 2.4 KHz and

we

could spread out like we do for every other mode.

I'm no expert, but I think that the coding could have enough error
checking to allow busted message frames to be printed (or converted to
CW) ... although of course with errors.  The extra error processing
would reduce the character count, though, all other things being

equal.

The point is that the digital signal processing behind FT8 is

extremely

powerful and could be adapted to other user formats with a lot more
flexibility than we have with FT8.  The hams who just dismiss FT8 out

of

hand really don't understand the broader weak signal applicability of

it.

[Rick Bates, NK7I]

Just as one can go from an electric or petroleum powered vehicle back to 
cart and horse (the common factor being wheels), doesn't mean that the 
history to get from there to here must be ignored (or honored).


It doesn't matter the mode, ties into history will still exist and can 
be honored (or ignored), even if elements are destroyed (statues or old 
unused modes).  And ham radio excels at exploring modes and methods.  
FT8 (and RTTY before that) is merely a stopping point on the line of 
history, something 'better' will come along (always has, always will, a 
constant) to fill the (momentary) needs.


The primary advantage (to some) of CW or phone is that it's human brain 
effort and skill, via the radio technology, that gives a sense of 
accomplishment (pride) while for some including the ties to history, the 
paths taken to get here.  For others, a complete technological contact 
with minimal effort, is what they seek and the world of ham radio allows 
that too.


All modes are valid and equal; just as casual, contest or rapid fire DX 
appeals to some, it suits the needs and purpose of the operator; to 
ENJOY what is available.


My satisfaction comes from using different modes (lately FT8 while it's 
popular AND CW and phone) to prove access to all parts of the planet 
(DXing) with a station that I assembled and built from what I could 
afford or manage to do the best (sometimes easiest) I can manage.  My 
'competition' is me, my motivation is always to do better.  I confine it 
with other limits too (budget, space used) because I don't want numerous 
towers or a super station and because that would affect my other 
enjoyable concerns (the view for one).


My preference is for a complete, simple station but that also means a 
group of single point failures exists (one of my choices).


If another has different ideals, there is room for that too, it's a 
personal set of choices.

Having both plus the KPA1500 (same height as the K4), that would be a

still allow for adequate cooling.


If they choose to go down that path, I'd hope they keep the third

Re: [Elecraft] MFJ 1234

I've used (successfully) a USB relay to momentarily toggle AUX line 8 (?

S-Box-USB and Y-Box system, which works in much the same way (and can 
remotely power on the Elecraft amps, cleans up cabling etc.).


Both methods require a computer that runs the 'turn on' file in bootup, 
OR being able to access that file from the main screen.  I have no 
problem leaving the station on at all times.


For whatever reason, only when I was > 1000 miles away did the power 
blip and the K3 wasn't there.  It got old to have someone go in, just to 
turn the radio off.  These methods took away that worry.


Even something as 'silly' as a Raspberry Pi toggling that AUX line once 
every XX minutes would work (and could provide other features).

things out and being a smart TV, it has other features for the shack but 
I added a Dish Joey too.


I've been using full QRO, all bands, no issues in receiving, no 
artifacts on the TV and it's cheaper than a monitor plus it has speakers 
so the desk has less on it.


The new shack is still coming together, but it's looking better each 
upgrade.  (I'd send a pic but I don't think qth.net allows that, so I'll 
update my QRZ page within a day or two.)

These
are great monitors. We use them in the hospital. RF pretty much immune. No
RFI generation and great for reading and Logging programs. Plus, They come
with 3 sets of cables. HDMI, VGA, Display port. I have 2 of these mounted
on this:

. It has 6 usb ports, 3 type 2 and 3 type 3. More than enough for an SO2R
set up. 2 for radios, 1 for controller, 2 for separate keyboards and 1 for
mouse. No Usb break out boxes. Clean Setup. The Lenovo is hospital approved
for high rf environments. It is totally a metal box and works great for
logging, web streaming/browsing and light gaming, Guild Wars, EQ, WoW. It
is my set up.

Best of luck in your choices.

Re: [Elecraft] Self-fusing liquid electrical tape

[Rick Bates, NK7I]

Or expense?  Lessee... 20 (ground rods including 5 at the tower) times 
$4 per clamp, vs $11-15 for little discernible gains.. adding over $300 
in my grounding solution.  Not a huge amount, but those costs add up 
quickly.  I went with clamps, all buried below grade.


I opted to tie the shop (barn) panel rod to the tower and the house 
panel rod and have a single run out into a field for future (RX antenna) 
use (and simply more earth contact to dissipate).


The copper wire was the cheapest element in play.

Re: [Elecraft] Problems with KRX3A

[Rick Bates, NK7I]

Gareth,

The information you have been given is correct but it's a challenge to 
wrap ones head around the details, a couple are subtle.


It is ultimately the items you have installed (the tuner, with the 
second antenna port) AND the connection of cables to the KRX3 (which 
connector source is chosen), THEN the setting in menu (KRX3 = ANT | BNC) 
to match those choices.


[The KRX3 will listen to ANT 1 | 2 with a tuner OR will listen to MAIN 
(whatever the main RX is using) | BNC; with or without a tuner (I think 
that's all inclusive).]


Then, the use of the front panel to engage which feed is in play, based 
on the options above (ANT 1 or 2; with a tuner| Main or BNC).


In my case, with a tuner (unused, one port to a KPA1500, the other to a 
dummy load) I chose to use the BNC as the RX source for the KRX3, simply 
so I cannot transmit into it, ever, and have diversity reception.  I can 
listen via main or BNC (RX system) and worry less about doing something 
stupid like blowing up the RX system and/or finals.


It also means that if I want the main receiver to hear the RX antenna 
(but transmit on the transmit antenna) I have to move a cable on the K3 
in the back (or provide a antenna switch), both are BNC, one is more 
challenging to reach through the maze of wires.


I'm hoping from the comments, that the K4 will be simpler to configure 
(on the fly) as most of us need simpler as we age ;-)   The most 
difficult part is deciding how one will use the tools most effectively, 
then put the parts in the right place to meet that/those goal/s.


None of which answers your original question.

I don't mean to be pedantic or insulting; I try to be complete because 
it's always the simplest of things that are the most elusive; details 
matter.


Assuming that the menu is set to enable a KRX3 and both SYN are showing 
expected results based on which SYN is installed (you've done this):


Hearing the rx audio 'rush' noise is a good start (use headphones, don't 
mix audio from the main RX); the audio stage is working, now look backwards.


Check the KRX3 filter selection to make sure that (a) the filter (menu) 
choice is correct (right filter) and (b) visually confirm the presence 
of the filter (DOH!) and (c) is actually IN the slot chosen (menu 
setting again).  Nothing is automatic, you tell the firmware what and 
where filters are installed.  (A quick test is to change the filter 
bandwidth on the front panel [B SEL or speaker/headphone audio]; note 
any audio changes from wide to narrow, if any.)


Then (if no success) I would start with actually seeing how the TMP 
cables are connected (you need to know anyway then change if needed to 
meet your goals); ARE they in the correct place; testing them along the 
way for continuity and shorting; then make sure that each is seated 
_fully_ (easy to miss) and correctly (hemostats or very small point 
pliers on the cable metal connector, very gently but firmly; tactile 
senses cranked up, damage is easy).  Do NOT ever pull on the cable itself.


Recheck the menu for the correct source settings again (in particular if 
you made changes).


If still no joy, based on your time difference to CA, an email of your 
test/findings to the repair team at Elecraft would be the best choice.


Please post your results, good and bad so others can learn too.

73,
Rick NK7I

Hi, Gareth.

Well...you certainly have a mystery here. I found the documentation in the 
Elecraft manual on this subject a little hard to follow; the book by Fred Cady 
on the K3 is better and, if you'd don't have have it, I highly recommend it.

I think you said on a previous post that you can hear the noise of the SUB when 
enabling it, then you are correct that there is something blocking the signal 
from the antenna.  Assuming the configuration is correct, it might be the cable 
inside the K3 that feeds the signal to the SUB.  When I opened up my K3 a while 
back to add a filter to the SUB. I noticed that one of the little coax cables 
entered the SUB at a pinched right angle (at least it was in mine).  While I 
didn't have a problem, it seemed like it could be a problem if I didn't make 
sure the little connector was firmly inserted.

I'm afraid I'm now beyond my pay grade on this...

Re: [Elecraft] Quiet Ductless HVAC System

Just as other appliances sold these days with a motor i.e. washing

the noise generated can reduce operator pleasure (or operating hours).


Getting any manufacturer to routinely add filtering (even if under $1),

I hooked up my K3 - Signalink - and it will not decode the K3S tones -decodes 
band signals just fine .
Makes no difference by band 80 or 10 the same and friend same on10 and 15 .
BTW the K3S decodes on air signals just fine.

This apparently happened in past week or so I do more listening than txing . 
Last FT8 qsos
in log were 5 /10 .

I uninstalled and re-installed WSJT -latest versions on both the K3 and K3S . 
No difference.

I went to earlier K3S config file - no difference.

Did an EEINT and still no difference-two different config files.

Makes no difference 5 watts,20 watts ,50 watts out of K3S. ,or 450 watts out of 
KPA . (all into dummy load on both xcvrs.)

Levels out of the computer are essentially same as always both rx and tx . Easy 
to get 4 bars ALC
with 5th flickering . Tones in monitor sound clean and looking at the monitor 
audio on scope they
are clean sine waves . The monitor signals look essentially the same on both 
the K3 and K3S.

Tried looking at recovered audio tones both ways - they look pretty much the 
same but hard to tell
dummy load to dummy load because of residual rx noise on the tones. Guess I 
could see if I could arrange to get
more signal.

Rig works on CW as always - dd not mess with SSB - Maybe I should look at two 
tone tomorrow --
or at least listen to it on SSB.

I restored computer W10Pro 64 bit to several updates ago and no change.
Rebooted computer - restarted programs . Clocks are within a tenth of a second.

I am out of ideas -other than to change the K3S over to using the Signalink 
instead of the USB/internal codec.
Guess I will do that later today since its 4 m.

Re: [Elecraft] Upper limits of KPA500?

[Rick Bates, NK7I]

I didn't add the obvious, FT8 in that manner is a 50% duty cycle but 
with enough time to 'catch the breath'.


I remember back when it first came out, Wayne suggested to 'run it with 
all the LEDs lit' or something along that line but... it's capable of 
MUCH more than 500 watts and wisely better limited by firmware upgrades 
(in the early days I watched it put out almost 700, at which point I was 
far more cautious).  It's nice to know there is a certain amount of 
'overhead'.

Re: [Elecraft] Elecraft K3s, etc. bonding

[Rick Bates, NK7I]

And in the meantime, lightning protection helps to reduce the noise and 
risks of 'everyday' static noise sources like wind, snow, blowing dust 
and even rain static.  HELPS, not removes.


Having (last fall) just installed a basic dissipation system, the 
difference can be quite startling and can allow one to hear a LOT 
better.  My noise floor also dropped from 10-35 dB with an average of 20 
dB the moment I tied it into the existing house safety grounds.  And 
that was not only increased safety but was cheaper than most low band 
reception arrays (which I'll add as well). 'New' DX; SCORE!


Just as any other station feature, one can continue to enhance or 
upgrade lightning protection and bonding over time until there is less 
return than cost expended.


One more often forgotten note:  ALL wiring coming into a building, must 
be bonded to the common safety ground; satellite dishes, telephone/DSL 
wires, cable TV... ALL of them or lightning will 'find a way' to ruin

Re: [Elecraft] KPA1500 Tuner Question for the Group

[Rick Bates, NK7I]

The KAT500 utility will show the LC values in play after tuning (and 
caps on/not on the antenna side) .  I expect that the KPA1500 utility 
will do the same thing; I'll know more next week when I put the KPA1500 
online (the new station and shack are almost completed).


I keep the entire station, including the KPA500 and KAT500 utilities 
running 24/7/365; this allows simpler remote station operations.  Plus 
it's nice to compare the SWR on both devices (though neither has ever 
been different from the other); belt and suspenders.  I don't keep the 
amp(s) on all the time, just when I'm actively using the station.

It has 2 outputs and keeps matches in memory. Getting it to tune at
frequency previously tuned takes a fraction of a second. If both antennas
were used at same frequency, tuning for one antenna automatically brings
tune in the second. Very convenient for A/B comparisons.

The tuner displays L, C and SWR.

Re: [Elecraft] Power supply for KS

Simply verify that the panel voltage is the same was what a known meter 
reads at the output, adjust the front panel meter as required.  (Most 
panel displays are off or simply not as accurate.)  Then one can use a 
permanent marker to place a line on the meter display, off the tip of 
the needle to quickly see any variance (in time, you'll squint less).

Re: [Elecraft] Power supply for KS

[Rick Bates, NK7I]

Wayne has said that 14.2V is desirable (as read on the display, so 
~14.4V at the source AND the input connector at the radio).  This 
provides a more clean signal.


It's also important to not allow voltage sag under load (for the same 
reasons).


Just make sure that if the power supply causes noise, that you can 
return it without cost.  Then your decision is switcher vs analog, each 
work well; each have issues or 'features'.

Re: [Elecraft] USB Noise core gets hot when operating FT*?

[Rick Bates, NK7I]

Jerry,

Ignoring how you've set up your station for the moment (every station 
has compromises but some push that to an extreme); the shutdown  of the 
connection is likely that RF got into the USB cable (as demonstrated by 
the hot ferrite) which caused the USB port hardware to lock up.


USB hardware can 'stick' so it won't work properly, a complete power 
cycle empties it of any charge, 'unsticking' the hardware.  (Yah a gross 
simplification, but you get the point.)


The only SURE way to restore it to function (assuming it's not blown) is 
a complete power down (unplugged from all power, let the power supply 
drain, disconnect the laptop battery, count another ten seconds) and 
restart.  That is why it worked after you 'cooled it off'.


If you can shift to a real serial port (not a serial dongle), that will 
help.  USB is RF intolerant compared to serial.  It's simplest to avoid 
USB as much as feasible near any RF.


If you can't avoid USB, you'll need to add a lot more ferrite or better 
yet, improve the antenna situation dramatically.


In the cases I MUST run a USB connection, I distance the antenna from 
the computer as much as possible and I run <100 watts (QRP to me), but 
generally that's when I run a portable station.  Jim, K9YC will tell you 
it's related to 'Pin 1' and the short version is that is has to do with 
bonding all things to a common ground; USB devices often ignore this.


In a few cases, improved bonding between the computer and radio /may/ 
help, but I'd have low hopes if the antenna is mere feet away.  Take the 
hot ferrite as a warning sign, it's not a healthy environment.

Rick NK7I

Re: [Elecraft] Electrolytic Capacitor failure

[Rick Bates, NK7I]

I guess I'm fortunate, I've had Astrons running 24/7 for decades without 
any failure.  A 20A powers my repeater (IRLP node, 25 watt), a 35A power 
the Elecraft products and I just installed a 60A rack mount to replace 
them both (all are adjusted to 14.2 for spectral purity plus I can 
charge LiFePo4 too).

On 4/17/2020 12:49 PM, Bob McGraw K4TAX wrote:
I have always been taught and thus have a concern when power supplies 
of excessive capacity are used for any type of service. If the wiring, 
in this case,  between the power supply and the radio is #12 or #14 of 
any length typically supplied by radio companies, should a short occur 
in the power cable, it is likely the power supply will deliver full 
current.  That will quickly melt the insulation on the power cable and 
could cause a fire before the power supply goes into current limit.


Now at the same time, each power cable could be fused at the supply to 
limit the amount of current the supply can drive into the cable.   I 
have to say I don't like this idea as the in-line fuse adds a 
significant amount of resistance and will impact the stability or 
degree of regulation of the voltage at the radio under a dynamic 
changing load such as SSB or CW.


All of this is no different than when one uses a battery for their 
radio.  In auto installations, for that reason, it is highly 
recommended that a fuse or circuit breaker be located at or very near 
the battery.    Same applies here where the supply is capable of 
delivering very high amperage.   I realize power supplies of this 
nature have over current protection.   However, 70 amps through #14 
wire will will produce lots of heat and smoke amazingly fast.


The correct solution is not so simple in one sense of the word. The 
better solution is to use properly rated supplies for the required 
load.   For that very reason, I have two 30 amp CCS rated supplies on 
my desk.  One feeds the Elecraft 100 watt transceiver while the other 
feeds the Tentec Eagle 100 watt transceiver.


All of my supplies have both voltage and current meters and they are 
in a position I can see them when I turn them on.  With supplies which 
do not have meters, when one turns them on, you never know in advance 
and get what they deliver.  In my case, I observe the meters BEFORE 
turning on a radio.  On more than one occasion this has saved a radio 
due to a power supply regulation failure.  Dumping 24 to 32  volts 
into a $3000 radios is not very pretty.   Oh yes, the supplies do have 
OVP, Over Voltage Protection, but I've seen this fail as well and I've 
repaired several supplies where this did fail.   And one doesn't know 
it has failed until the voltage goes to maximum value.   Its too late 
then to find out the OVP circuit has failed.   A meter would have 
prevented radio and accessory equipment damage.

Re: [Elecraft] KPA500 problem

[Rick Bates, NK7I]

It's not elegant but I just finished a rack/table using a butcher block 
top (Home Depot) and angle stock on the front inside of the 2x2 wooden 
legs to mount the p/s and a repeater I use for IRLP (duplexer later, one 
pieces at a time).  The table top is stained and matches the height of 
the desk so there is almost a continuous surface.   Five coats of poly 
should suffice to seal it.  More angle stock from the front to back legs 
will support/share the weight for each item, so it's not entirely held 
by the front.


The K3, P3 and KPA1500 will sit on the desk within reach, just below the 
50" monitor (4K TV) mounted to the wall (swing/tilt mount).  The KPA1500 
amp p/s will sit on the table top but may end up in the rack later.  The 
KAT500/KPA500 will be nearby as backup, easily added if needed.


The next step is to add copper pipe along the equipment space to behind 
the desk for equipment bonding to ground, then add a shelf on either 
side of the monitor to hang speakers, rotor and SteppIR controllers and 
the control head of a dual band with some books too.  (There is also a 
small frig and microwave next to the desk.)  Then put a 36x36" piece of 
plywood on the wall (that wide so it can be well anchored by the 16" on 
center studs) for dual band, 6M FM radio and perhaps more later.


The entire station (and network) is all going to run from a UPS, which 
only has to last long enough for the generator to kick in (about 40 
seconds) so nothing drops out during an outage (except the large amp, on 
240V).


Most of the wiring will be hidden by desk or monitor, except the space 
above the table, where they come in from the tower (large conduits, 
buried in ground).


The floor is industrial laminate, the rack and desk have sliders (easily 
moved when wanted, no wandering).  A computer manages each piece, then I 
can remote into that computer from the warm house or when traveling.


It's a simple station, the 80-6M SteppIR up 60' and an 80/160M Inverted 
L.  Simple ROCKS!

Yes. I wish I had thought of doing something like this after seeing

about 2 inches for cables to pass vertically between shelves. That

Bill,

I don't have a W2 so I cannot comment there, but two things stand out 
that need mention.


1)  Regedit is NOT the place to wipe out a program.  If you (as you 
said) don't know much about Windows, it is however the perfect place 
to make an unrecoverable error and trash the entire computer.  It is 
one of the core elements of the OS.  If you don't understand, don't 
attempt here, it's a dangerous place to learn (by mistake).


2a) The Windows key (four small window panes) with B /_*may*_//__/ 
bring that errant program back into viewing ability. (Windows B at 
the same time)


2b) Use the Task Manager (right click on the taskbar at the bottom) 
to 'End Task' if you can't get the upper right X to kill it. Ending a 
taskwill lose whatever changes you've made in that application since 
starting it but that's often a cause of the issues too.


If you wish to remove a program, uninstall it. If you wish to clean 
or purge the registry of residue (and other things), use 'CCleaner' 
(Crap Cleaner) which will do it with intelligence and safety.  It is 
free but has the (nasty) habit of wanting to stay running in the 
background, so get into the program settings and turn that 'feature' 
off.  You'll be amazed and how much 'stuff' gets purged if you use 
this app.


When CCleaning a _registry_, run the cleaning cycle again until it 
says nothing found.  Removing one old piece in the registry often 
causes others to not be needed as well.  Three times is 'usually' 
enough passes.


CCleaner MAY not get all the folders that installed software leaves 
behind, you have to hunt and dispose of them manually and CAREFULLY.  
Again, this can be a dangerous place to play if you don't understand.


(I've used CCleaner for years, I'm not a shill.)

After you've done this, then you can reinstall the software if you wish.

Now, back to the topic of the W2 software. Practice safe computing, hi.

Re: [Elecraft] question on W2 wattmeter interface application

[Rick Bates, NK7I]

Bill,

I don't have a W2 so I cannot comment there, but two things stand out 
that need mention.


1)  Regedit is NOT the place to wipe out a program.  If you (as you 
said) don't know much about Windows, it is however the perfect place to 
make an unrecoverable error and trash the entire computer.  It is one of 
the core elements of the OS.  If you don't understand, don't attempt 
here, it's a dangerous place to learn (by mistake).


2a) The Windows key (four small window panes) with B /_*may*_//__/ bring 
that errant program back into viewing ability. (Windows B at the same time)


2b) Use the Task Manager (right click on the taskbar at the bottom) to 
'End Task' if you can't get the upper right X to kill it. Ending a 
taskwill lose whatever changes you've made in that application since 
starting it but that's often a cause of the issues too.


If you wish to remove a program, uninstall it. If you wish to clean or 
purge the registry of residue (and other things), use 'CCleaner' (Crap 
Cleaner) which will do it with intelligence and safety.  It is free but 
has the (nasty) habit of wanting to stay running in the background, so 
get into the program settings and turn that 'feature' off.  You'll be 
amazed and how much 'stuff' gets purged if you use this app.


When CCleaning a _registry_, run the cleaning cycle again until it says 
nothing found.  Removing one old piece in the registry often causes 
others to not be needed as well.  Three times is 'usually' enough passes.


CCleaner MAY not get all the folders that installed software leaves 
behind, you have to hunt and dispose of them manually and CAREFULLY.  
Again, this can be a dangerous place to play if you don't understand.


(I've used CCleaner for years, I'm not a shill.)

After you've done this, then you can reinstall the software if you wish.

Now, back to the topic of the W2 software. Practice safe computing, hi.

73,
Rick NK7I

Re: [Elecraft] Off-Topic - Antenna element repairs

[Rick Bates, NK7I]

If you can find a length of tubing one size larger (so that the pieces 
to be repaired just barely fit inside); cut a length long enough to 
provide lateral strength (side load), cut slits into the ends of the 
patch lengthwise then overlay that to 'mend' the two pieces (make it 
continuous again) and use worm gear clamps on the slits to bind it 
together (making sure that the original two parts are close so you don't 
have to trim to resonance).


The overlaid section will be stronger than the original (two layers) if 
you do this correctly and have a long enough patch (which will depend on 
the overall length since length gives leverage).


Some will suggest also adding conductive grease on the elements 
overlapping.  Other may also suggest adding two (at each end) small 
bolts at 90 degrees to each other to back up or replace the clamps 
(belts and suspender mode).  I don't suggest bolts as they're hard to 
realign next time and reduce the amount of material needed at the patch 
(makes it weaker).


I've also (because it was available) taken fiberglass rod and put that 
INSIDE the two aluminum ends, with bolts to keep it in place and a clamp 
to span any distance between the ends.  It worked but isn't as 
electrically sound.


I would not use a pop rivet, it's not bonded hard enough to the elements 
(you'd still need an overlaid section), isn't strong enough over time 
and could create a weak enough contact point for RFI later.  Brazing 
also brings in a dissimilar metal and creates even more issues.

Re: [Elecraft] Off-Topic: Your advice/suggestion about antenna

[Rick Bates, NK7I]

Duane,

I agree on both points.  The antenna is THE most important element of 
any station (the accepted maxim is it's 90% of the budget but most hams 
are 'cheap').  The radio is useless without a decent antenna.  An EDZ 
can work well but the peaks and nulls vary on every band and wind in the 
trees can be an issue.  Height matters, a LOT too.


I also hid (in plain sight) a similar 370' EDZ (at 35') antenna IN the 
HOA space (shot a wire over some oak trees) for years without it being 
seen and it worked well (other than the noise floor was obscenely high, 
all the time because it was urban).  It absolutely ROCKED on 40M (the 
noise precluded hearing much on 160M but I got 15-20 countries).


If budget is less of a concern, you might want to consider SteppIR, 
starting with the 2 element Urban beam (40-6M).  The only other comment 
along that line is leave a LOT of headroom capacity when selecting a 
rotator, they take a lot of wind abuse.  There are other beam antennas 
worth consideration, many are less expensive.


When I moved away from the HOA infestation area into rural with a 40 db 
(average) lower noise floor, in time I went from all band (R7, dipole or 
vertical) wires to a SteppIR DB36/80 (80-6M) which gave me an average of 
another 10 dB of GAIN in reception (plus directivity to null noise even 
further AND transmit gain too).


I bought the antenna, rotor and tower at an estate sale (SK sale), 
saving many thousands of dollars.  The son (a non-ham) just wanted it 
all gone, I assisted ;-) so keep watch, ready to 'attack'.


The sole remaining wire is an Inverted L for 160M.  I greatly prefer 
this to any dipole because the one wire is not pulled/stretched between 
multiple trees when it's windy (and the trees NEVER sway in sync at the 
same moments).  It moves precisely WITH the tree motion, it isn't 
stretched or pulled.  However, it's moderately deaf on 160M, I'll have 
to add an RX array (RBOG or 8 square are the current considerations) yet 
I'm now at 131 countries worked on 160M.


The sole sticking point remaining is my requirement that NOTHING antenna 
can be seen from the house (I bought an amazing view, it came with a 
house), so even with the acres I have, I'm limited to a few acres total, 
further reduced by proximity to the power lines along the road.  
Fortunately my neighbor (700' away) is also an HF active ham with even 
more acres (same visual rule) so we're considering a shared RX array 
(SDR and wifi based, which removes much of the desense issue too).


So my suggestion is that you look at the larger picture and perhaps even 
start fresh, not re-modify the original plans (make it a Revolution, not 
just an evolution).  Part of my move (escape to) here was just for that 
reason, to start with a fresh station based on simplicity of operation 
(which takes a LOT of planning and work to obtain; in a couple years, 
it'll be there, I hope.)


GL,

Duane -

  


I am of the mind that the antenna is the most crucial part of any station,
and probably the most often maligned.  I have made a number of presentations
to ham groups on the design and construction  process involved in getting
the most bang for the buck, depending on your wants and needs (everybody's
are different).

  


In my own situation (2 acre semi-rural lot approx.150 feet x 600 feet
running E-W feet, and active HOA) the goal was to have a single antenna that
would provide the best primary signal on 80 meters in a North-South
direction, while providing the best possible signal on 40 meters in an
East-West direction, consistent with the 80 meter performance and without
unduly provoking the HOA (or my XYL).

  


I decided on an Extended Double Zepp, cut for 3.5 MHz.  That resulted in a
length of 360 feet, which worked nicely since I have 400 feet clear from the
house (West end) to a perfect tree for the far East end.  And another tree
in the center for support of both the antenna and the feedline.

  


I am feeding it with a 160 foot length of 600 ohm "true ladder line."  I can
go into more detail if this sounds like something that would work.  Modeling
this antenna with EZ NEC shows a maximum theoretical gain of 4.7 dbi in both
North and South directions.  With the ladder line, a dual hybrid balun and
short length of coax into the shack, my KAT500 tunes it very nicely on all
bands 160 m thru 6m.

  


I don't have your call so can't see where you are, but would be happy to
make other suggestions based on the coverage you seek.

Re: [Elecraft] KAT500 antenna selection

[Rick Bates, NK7I]

I'll submit that the KAT500 was designed long before 630 meters was 
generally open and the values needed to present a low SWR are far larger 
than needed elsewhere.  Anything below 160M is a 'specialty' band that 
far fewer will attempt.  However you COULD go through the values that 
the KAT500 offers manually and see if something could work.


You could use an antenna analyzer in SWR mode (fixed freq not sweep) to 
tune the antenna at almost any frequency (at flea power, all legally).

You bring up some good points, and I will be watching for the input from the

One issue I have with the KAT500 is that it only goes down to 160 meters.
My previous tuner would handle much lower frequencies, allowing me to work
630 meters.  No such luck with the KAT500.  If there is a workaround, I'd
like to hear what it is.

Also keep in mind that tuning it on "off band" frequencies requires that you
transmit a signal of at least a minimal value ... which is technically not
legal.

The KAT500 has continuous frequency coverage for saving and selecting tuning
solutions and is not constrained to amateur band limits.  However, the
antenna selection can only be defined for the amateur bands.

Does the KAT500 simply use the antenna selection defined for the amateur
band closest to the out of band operating frequency?

Re: [Elecraft] Extra Protection For KPA500?

While you're adjusting the output drive for the amp on each band; make 
sure it's EACH band, including 60M (100 watt limit in the US) and 30M 
(200 watt limit in the US).


Yes, those bands also, because operator error (fatigue, excitement, 
rush, brain slip) WILL happen and having those QRP bands preset in the 
amp could save you grief.

Re: [Elecraft] Extra Protection For KPA500?

[Rick Bates, NK7I]

Don et al,

On occasion the signal that the amp goes into Operate mode is not passed 
along (or received, I don't know which), which means that the K3 will 
operate at higher than required drive level, for a moment only because 
the KPA500 will fault VERY quickly protecting everything.


However, I am unable to come up with a viable pair of suspenders, so I 
simply try to be more aware when the amp goes hot.


The reverse can be true too; the K3 thinks the amp is still in operate 
(but it isn't) and transmits at lower than expected output.


Yes, I've dis/reconnected the cables, made sure they're snugged in; it's 
not repeatable, it's random.  I do use the two cables (6') which is the 
max allowed between the K3 and KPA, which may also be part of the 
cause.  (Moving it all into a new shack over the next few days, that 
cable length will no longer be required.)

If you are operating a K3 or K3S, there is a per band power level that 
can be used.  It will automatically use the settings for the amplifier 
when the KPA500 is set to operate.  That can be considered your 2nd

Re: [Elecraft] Unusual Behavior K3S / KPA500 Drive Power Greater Than 12 watts

[Rick Bates, NK7I]

12 watts is the transition point for the high(er) power amp in the K3 to 
engage, so it's feasible that as that happens, the LPA drops it's output 
some to make the set power out (to not immediately put out 100 watts but 
what the reading says it should be).


If the K3S has normal output when you're not adjusting the power out, I 
wouldn't worry about it.


If the K3S in CW is set for the desired power output, phone will be also.

Rick Et al:

The K3S makes 110 watts measured so the rigs finals appear to be just 
fine. Audio is also clean with no distortion. After further testing, I 
found that the power drop is only momentary.


The RF output on the KPA500 does drop when the drive on the K3S is 
increased from 12 to 13 watts, but it quickly rebounds to it's normal 
output a few seconds later.


This happens on all bands and only takes place during the transition 
from 12 to 13 watts. I can hear a relay click during the 12 to 13 watt 
increase which happens to coincide with the momentary condition 
described above.


Whatever it is, something changes the way the transmitter behaves 
momentarily during that specific power change and my guess is that 
it's not unique to my K3S.


I spend most of my time on CW and little on SSB so I never noticed 
this before. Other than that, the K3S and KPA500 work flawlessly.

accidentally on?


What power output can you read when not using the amp and going above 
12 watts?  If more than 12 watts, a calibrate output would be in

Is it confined to one band?

If you don't get direction of the cause from these tests, a phone

Re: [Elecraft] Flex6600 + KPA500 + KAT500

[Rick Bates, NK7I]

I'm not sure about how much the Flex demands the CPU, but I have the 
KAT500 Utility and the KPA Utility running while a third port manages 
the K3 (via HRD).  (A 4 port real RS-232 board in the computer, USB 
doesn't always play well in QRO environments; the 4th port manages 
keying CW and FSK while AFSK is still an option.)


These apps give me insight (SWR, power out etc) and control (standby, 
operate. switch antennas) over the transmitting and antenna elements 
(well, add PSTRotator for rotor and SteppIR control).


The key here is to make sure that it all runs on one computer successfully.

Since my station all runs on one computer at the same time, when I 
remote the computer, I remote the station (TeamViewer).  I add in Skype 
for audio (CW and phone).


So yes, it should be possible for you.  One bonus is that you're running 
your station (remotely or not) and no one has to know where you are and 
your log is accurate since it's based on the station location, not yours.

As best I can tell you can only connect a single KXUSB cable to the KAT.

Logged in under 2 minutes from the listening start; Yay Elecraft (K3,

Re: [Elecraft] KPA1500

[Rick Bates, NK7I]

Presuming that is a known 'good' dummy load for that power level, have 
you run the output calibration of the driver radio (K3/S also presumed) 
as a starting point?


If that has been done (successfully, multiple times), check to make SURE 
that the radio (driver) antenna tuner is BYPASSED (not presenting an odd 
load into the amp).


Watch CAREFULLY that the driver output is constant (no dirty control, no 
spike etc.).


Then it's time to be concerned about the 80M tuned input circuit failing 
on the KPA1500 and call Elecraft for specific tests.  When the amp sees 
>=19 watts input, it wigs out, badly.  (But the extreme outputs ARE 
impressive; it's nice to have overhead at legal limit).


GL, please let us know how it was resolved,

Re: [Elecraft] When might there be a P3 sale or drop in price

[Rick Bates, NK7I]

And don't forget that the P3 is actually an almost complete receiver 
(minus audio).  It just 'happens' to listen to the IF of the K3.

The P3 in my experience is far easier to use under practical operating

the band, or zoom out to see across the band.  You can easily adjust to put the 
noise floor at the bottom of the screen and adjust the height of signals so it 
all becomes more easy to follow.All of this can be done quickly with one 
hand.

Are there plans to have a sale or bigger discount?

Re: [Elecraft] QRO - KPA500 Failure

They self-insure OUTbound from Elecraft; it falls on the shipper to 
insure, not the recipient.


I had to send in the RF deck (only) of the KPA1500 for factory upgrades 
and I asked for Elecraft to cover shipping.  I waited a few days.


An hour after I got back from shipping it UPS from Idaho (the insurance 
was a killer, total bill ~$180), they approved paying for it.  DOH!


Ask, then be more patient than me.  The worst answer is 'no' and that 
only costs you time to find out.

Re: [Elecraft] QRO - KPA500 Failure

[Rick Bates, NK7I]

Since the SWR is still nominal into the amp (as shown on your radio), 
it's not likely the tuned input circuits (which is confirmed from no 
output on all bands).


This points to the high power module.  Running low output power from it, 
is far less efficient than pushing it hard (compare wattages consumed to 
RF watts output delivered at different output levels); which may have 
stressed the finals.  Ideally you run the previous stages at 
low-moderate power for lower IMD, then punch it up with the amp.


The "HIGH SWR" fault you saw is then very likely the final signing QRT 
SK.  You can confirm that with Elecraft wizards.


That module isn't hard to swap out, but it would be best (slightly more 
costly) for the entire amp to visit it's parents, so that other updates 
that may not have been done, can be done. Many of them, really matter.


While also not cheap in shipping and insurance (ask me how I know?) that 
is often the better choice.

Anyone else have this problem?  Maybe the AF gain pot needs to be replaced?

shipping the PA deck from the KPA1500 ($170 insured), I got the label in 
the email.  Oh well. It was out of warranty (but unused until the shack 
is completed; very soon now).


I always, always ask for discounts or similar; the worst possible answer 
is 'no', which costs me nothing yet sometimes provides a nice savings.


73 es Merry Christmas,

I purchased a KX3 "Shack-in-a-Pack" a year ago, and after making one contact 
QRP at 5-watts, I set it aside in its carrying case while I took care of other 
commitments.  Last week, barely three weeks before the end of the warranty period, I 
brought it out and started working with it, studying the manuals, and figuring out how to 
use it.  I immediately discovered that transmitting into a 50-Ohm dummy load and pressing 
ATU TUNE returned an SWR of 25.4:1.  Discussions with 'Rob,' Elecraft technician, were 
not productive; i.e., the results that should have been obtained weren't there.  
Eventually I discovered that while it said I was transmitting at 5-watts, the RF 
indicator was reading el zippo.  Rob sent me a Repair Service Authorization (RSA) and I 
returned it to Elecraft for repair.  It took two days to get there and one day later I 
received notification that the KXAT3 board had failed, had now been replaced, the unit 
calibrated, and all is copacetic!  I am writing this to cr
  ow about the wonderful service offered by Elecraft, especially approaching 
the Christmas season!  (My only complaint is the $57 it took to ship it and 
insure it for $1400, but that is not their fault.)  I am very happy with 
Elecraft and I am looking forward to doing some serious QRP work when it gets 
back.

Re: [Elecraft] KAT-500 problem

[Rick Bates, NK7I]

Check ALL your coax connections (and quality of coax), making SURE that 
the connectors are properly attached (soldered or crimped) to the wires 
AND that they are securely attached to the mated connector on the KAT500.


A /little/ leakage is normal but unless that station is 40 over 9, you 
shouldn't hear it.


My first guess would be that something failed or came loose.

I have a KAT-500 at least 4 years old.  I can hear stations without any
antennas connected to it.  I live in Clarksville, TN and I copied  station
in Bradenton, FL 600+ miles away on 14.3 MHZ.  I have had the same thing
happen on 40 meters as well.  Any ideas???
