Re: [Elecraft] K3/N1MM, freq jumps etc in CQ WW CW

[Ignacy]

Thank you for comments. I amy indeed use ` by chance although I have not done
SO2V by choice.

N1MM claims a bug in K3. 
This is in
http://n1mm.hamdocs.com/tiki-index.php?page=Supported+Radios#K3_and_K3S:

*The K3 contains a firmware bug that was reported several times and never
been fixed which affects users who would like to use PTT via radio command.
If the Esc key is pressed when a CW transmission begins and you are using
PTT via radio command, the radio may not return to RX. The radio RX issue
doesn't occur if the owner disconnects the CW jack from the rear of the K3
radio and doesn't change any N1MM Logger setting. Similar issues have been
reported on other modes. Delay has been added to the N1MM Logger program
when Esc is pressed but the problem still occurs intermittently. The problem
seems to be worse with the very early K3 radios. Until this firmware issue
is corrected, users may notice that the radio does not return to RX
intermittently when using PTT via radio command. When this occurs, make
another transmission and end it with the ESC key.*

Ignacy, NO9E

Re: [Elecraft] Ready to Purchase KX3 and PX3 - Would Like Advice on accessories and "must haves".

[Michael Murphy]

Matt,

Obviously you drank the koolaid as I did.  I have both the KX3 and K3.

I will echo what Walter has already said about the Gemsproducts Side KX3
and cover.  I bought them for mine and am glad that I did.  It does a great
job of protecting the rig.

The only other thing you might look at is a good external speaker for use
in the shack. I have used the West Mountain speakers (
http://www.rffun.com/catalog/speakers/5042.html) which don't have RFI
issues and was pleased with them.  I now use a pair of JBL near field
monitors through a mixing board.

Enjoy the new rig!

[Elecraft] Ready to Purchase KX3 and PX3 - Would Like Advice on accessories and "must haves".

[Mark Tosiello]

Hi all!!


I'm preparing to purchase the KX3 and PX3 kits. I'm planning on the ATU and
Roofing filter options, as well as the battery charger and clock. I'm also
planning on purchasing the Powerwerks switching PS and the power supply
cable for the PX3.

Initially, I plan to use the system as a QRP CW/Phone (mostly CW) rig. This
will supplement my main 100w rig (and IC-746 Pro). Hopefully, the
sensitivity of the receiver will help out during phone and CW contesting as
well!. During The winter months here in Michigan the KX3 will stay in my
station, and come summer I'm hoping to operate from various locations here
in Traverse City.

I want to be sure that I order all of the parts that I need so that once
the kits are built, I can get on with the fun on the air.  As far as I
understand it, I'll need:

*Main Items:*

KX3 Kit
PX3 Kit
Power Supply for KX3
Powerpole terminated cable for above.
Power Supply for PX3

*Connectors:*

All of my antenna feed lines terminate with PL259 connectors. My research
suggests that I'll need a BNC Male to SO239 adapter, as well as (for
convenience) a right angle BNC-BNC connector. Is a right angle male BNC to
SO239 connector available?  That would be ideal.

I'm waffling on the paddles, as I have 2 beautiful sets of brass K8RA P-4
and P-3 paddles to use in the shack. Probably a later purchase. I do have a
question, however, regarding the charger. Will the internal charger charge
LiPo batteries or only NiMH?  Can LiPo batteries be used in the unit if
charged with an external charger?

I'll also need cabling to connect to my Windows 10/7 computer; I think this
comes with the unit but thought I'd better check.

Thanks for all of your advice and experience with the KX3!  I'm excited!

Only NiMH.

No. AA batteries only.

The consensus recommendation for internal batteries is Eneloop XX. Those are 
high-quality, high-capacity, low self-discharge batteries.

You don’t need a right angle BNC unless you want to dress the cables that way. 
I don’t use one.

I highly recommend the SideKX endplates and covers if you ever want to take the 
KX3 off your desk. High quality protection and a deal at $69.

Re: [Elecraft] Ready to Purchase KX3 and PX3 - Would Like Advice on accessories and "must haves".

[Matt Maguire]

I would recommend getting the KXAT3 antenna tuner option, especially if you are 
planning on operating portable. Maybe also the BNC binding posts connector, 
depending on what antenna arrangements you are planning for your portable ops.

For the shack, if you have some nice paddles already, I would suggest just 
using those. If you are operating portable, the KXPD3 paddles are light and 
convenient.

Internal charger is for NiMH cells only. You can use an external LiPo battery, 
although I prefer LiFePO4 batteries myself (they are safer, and the voltage 
output from a 4S pack is ideal, whereas the output of a LiPo pack is likely to 
be too low or too high). You of course need an external balance charger 
designed to work with the specific battery chemistry you choose.

If you plan to do phone, you’ll need a microphone. You can order one from 
Elecraft, or you can use a computer headset. The radio does not come with any 
cables (except a flying lead power cable and USB cable), so you should order a 
cableset if you want to connect the audio to a PC soundcard.

You also might want to consider purchasing Fred Cady’s book on KX3 (hard copy 
or PDF). Lulu is currently offering a 25% discount on hardcopies with coupon 
code HOLIDAYS25; otherwise you can order it from Elecraft or from directly from 
Fred KE7X.

Re: [Elecraft] Ready to Purchase KX3 and PX3 - Would Like Advice on accessories and "must haves".

[Marc Veeneman]

Hi, Mark.  I have 3 KX3s, 2 of them here in Grand Rapids and the 3rd in Vermont 
at our summer home.  I used the KX3 for a single operator battery powered Field 
Day in 2014 on the deck in Vermont, so even have a bit of portable experience.

I think I can answer all your questions, but first let me say you're getting 
probably the single nicest rig available.  I do have a K3/P3 here on the desk 
next to my KX3/PX3/KXPA100 but rarely use the K3.  Both my 80 meter dipole and 
the G5RV are hooked up to the KX3 system.

I also have both the dual paddle and single paddle K8RA keys.  They are larger 
and heavier than the rig!  They're excellent keys and the single paddle is 
about as nice as they come.  However they aren't style matches to the Elecraft 
gear so I usually use my 9A5N paddles instead.

But what will you need?  Start with right angle 3.5 mm stereo plugs.  When you 
put the station together you'll find it's a mass of cables.  The Mike, Key, and 
Earbud jacks are all on the side of the KX3 that abuts the PX3.  They all 
deserve right angle plugs.  I finally bought some right angle adapters so I 
could, when needed, use straight plugs.

Get yourself a 3.5mm stereo Y cable so you can use both paddles without 
switching anything around.  I do that with the single- and dual-lever paddles.  

When I was comparing paddles to see which kept me most mistake-free at higher 
speeds, I actually used serially connected Y cables and 3.5mm male to 6.5mm 
female adapters so I didn't have to rewire the paddles and keys I was testing.  
At one time I had 8 keys all active simultaneously into the single KX3 "key" 
jack.

Yes, you'll need to convert BNC to SO239 and you'll want a right angle 
male-to-female BNC adapter -- again to keep things looking neat and keep 
cabling aimed away from you.

If you get a KXPA100, it'll come with a right-angle BNC connector on a short 
cable with a PL259 on the other end.  I'm sure you could buy just that from 
Elecraft and then use a dual SO239 to connect to your coax.

So -- think right angle and you'll be set.

The receiver on that KX3 is wonderful.  You'll love it if you do much CW work.

73,

[Elecraft] [K2] Tuning a magloop with KAT100

[Dave Lankshear]

Hello, Brian.

 

I've read your post and the replies and figure I maybe read what you said
incorrectly, but you did say:

 

Then use the TUNE button on the K2 to tune the loop to resonance, then
operate.

 

You can't use the K2's antenna tuner to tune a loop to resonance.  That's
not how they work.

 

The loop is a complete tuned circuit in itself.  There's the loop
representing inductance and a capacitor in parallel with it.  These are
resonant at a frequency and the only practical way to move that resonant
frequency is to adjust the value of the capacitor that's in parallel with
the loop.

 

You can't adjust that resonant frequency using an auto ATU at the end of a
length of coax.  It's rather like using a telephone conversation to make a
physical change at the other end.  You can't use the phone to make the beds
back home, when you're away!  The auto ATU will see the coax cable and the
loop as a lump of L and C and will endeavour to match it to 50 ohms to get a
1:1 SWR.  The coax forms part of the antenna and is not behaving like a
transmission line and the loop is not behaving like a resonant circuit - you
might just as well hook the coax to your automobile's fender and use the
auto ATU to tune that!

 

Please forgive my descriptions if I have misunderstood your question, but
re-reading your quoted statement makes me feel like I'm the only one who has
understood.

 

Yes, by all means match the auto ATU into 50 ohms using a dummy load.  That
way, the PA is looking into a load that matches the impedance of the
transmission line, although as Don suggested, you don't really need the auto
ATU (and its losses) as the PA should be reasonably well matched by
bypassing the auto ATU entirely.  Now, at the loop end, there's a gamma
match arrangement that ensures the loop, when at resonance, is a decent
match to the 50 ohm transmission line you're using.  So the rig matches to
the transmission line which matches to the loop that's been tuned to
resonance with its inbuilt tuning capacitor.

 

A loop is only a single turn coil, the resonant frequency of which is varied
by adjustment of its parallel capacitance.  Because it's small and is a low
loss inductor operating with a low loss airspaced (or vacuum) capacitor, the
Q factor, or "goodness" of the single turn coil at resonance is very high.
This means that a small excursion away from resonance, the loop's Q falls
very rapidly and renders it pretty useless, thus it is necessary (more so
when transmitting through the loop) to retune it for frequency shifts of
more than a few kHz.  That means that the SWR rises rapidly away from
resonance and the coaxial cable is more involved in becoming part of the
antenna and less of a transmission line.

 

The outer surface of a loop (well, outer 6%) needs to be of very low
resistance in order to maximise Q at resonance.  RF skin effect uses only
the outer surface of the conductor, thus the larger the surface area of the
conductor, the more its internal resistance is in parallel and thus reduced,
so the better performer the loop becomes.

 

Even a soldered joint on copper piping offers resistance that compromises
the loop's performance.  Recently a friend gave an old army magnetic loop to
a group of collectors/militia enthusiasts.  It was in poor condition, but in
its prime, its surface area must have been a foot across.  This makes a
mockery of the little bits of aluminium (aluminium) joined together with
bolts and wing nuts.  Yes, says the vendor, it is broad banded and only
needs retuning every 100kHz or so.  What he doesn't say is that its
resistance makesthe Q so appalling that its performance is lousy (where
lousy is the polite word), but those devices give properly engineered mag
loops a bad name by tarring all with the same brush.  Also, there are
proportionally more crappy mag loops out there simply because they are
cheaper than the "real" thing.  

 

The MFJ 1782/86/88 aren't too bad and are just at the crossing point between
good and bad, with a bias towards the good, if not too many spiders and
other insect life are resident under the black covers. These loops have an
airspaced variable capacitor within the black covers and that capacitor is
tuned by a small electric motor that's attached to it.  DC power for the
motor is fed down the coax cable itself, as well as the radio signals.  They
are not difficult to separate, eliminating the need for a control cable.
The DC voltage on the coax is reversed in order to make the motor turn in
the opposite direction.  The more sophisticated MFJ controller has an
inbuilt cross-needle SWR meter and the name of the game is to get the SWR as
low as possible on the operating frequency.  Their semi-automatic controller
drives the motor and detects the lowest SWR point and stops.  Of course, to
detect the lowest point, it has to begin to increase again, so it always
stops at a point that's not quite at resonance and this must be fine-tuned
by the operator, hunting to and

Re: [Elecraft] [K2] Tuning a magloop with KAT100

[Don Wilhelm]

Dave and all,

You only have to put the tuner into Calibrate.  For the KAT100 it is ATU 
CAL.
The TUNE button will then simply put out a carrier (the KAT100 will not 
tune, but is effectively bypassed).  With the KPA100, that power will be 
limited to 20 watts or if the Power Knob is set lower than 20 watts, it 
will put out a carrier at the set power.  If it is significantly higher 
than that, the KPA100 wattmeter has a problem.

You can't use the K2's antenna tuner to tune a loop to resonance.  That's
not how they work.

Re: [Elecraft] [OT] Lulu sale on KE7X books

[Terry Schieler]

I was up in the air about the best KE7X publications to purchase for my 
particular application.  I ventured to Fred's website www.ke7x.com and found 
that he had created a nifty new home page, much easier to navigate than in the 
past.  You'll find a handy chart that helps you match your needs with the 
proper book(s) and shows which vendor has each book available (not all vendors 
have all books) and in what format.  The FAQ section addresses practically 
every scenario possible with the Elecraft products and Fred has invested 
notable effort in helping make sure you don't inadvertently purchase more of 
his publications than you really need.  It cleared up my questions quickly.

You won't find those kinds of "don't buy more of my products than you really 
need" helpful hints often.

Hi Matt,
The KX-Line book is up-to-date for the KX3 and KXPA100 material but the PX3 
chapter is missing the recent keyboard terminal information.  I'll make up an 
addenda for that but probably won't incorporate it in a new edition for a while 
yet, although I could put it in the KZPA100 update book.

Re: [Elecraft] K3(S) or KX3. Add function to Utility to save non-radio specific settings

[Walter Underwood]

Saving and restoring settings through a documented API should be pretty danged 
safe. It is something that is requested every couple of months.

I deal with script kiddies writing web bots every week at work, but they don’t

Re: [Elecraft] K3/N1MM, freq jumps etc in CQ WW CW

[Ignacy]

I checked my setting. It was SO1V all the time. 

Regarding locks. I tried it again.

When running, press RIT then XIT. The display shows ERR KEY and the radio is
stuck in TX. Not big deal as I can turn it off and on. But weird.  

This may be something to do with software PTT.

Re: [Elecraft] [K2] Tuning a magloop with KAT100

[Fred Jensen]

Don is right of course.  If you want a mag loop to actually act like an 
antenna, it MUST be exactly resonant on your transmit frequency ... 
period.  No antenna "tuners," which have never "tuned an antenna" 
anyway. Bypass the KAT2/KAT100 or whatever.  Tune the mag loop cap to 
1.0:1 ... not 1.5:1 or "close" ... 1.0:1.  The K2 will tell you this. 
That's all you do.


100W into a small mag loop probably exceeds it's ratings by close to an 
order of magnitude, and please don't do it if I'm sitting next to it. 
:-)  These are QRP field antennas.

Re: [Elecraft] K3(S) or KX3. Add function to Utility to save non-radio specific settings

[Mark, KE6BB via Elecraft]

Re: "The configuration saved also includes calibration data for that 
particular radio."
The request is for a way to save and reload user settings OTHER THAN the radio 
cal data.  That way it won't be radio specific.  Can't say that I would ever 
use that feature, but it makes a lot of sense for expeditions,  field day, etc.
As Walter mentioned, this comes up every couple of months or so.

Re: [Elecraft] K3/N1MM, freq jumps etc in CQ WW CW

[Mike K2MK]

Hi Ignacy,

Is it possible that when you decided to end your transmission you quickly
moved your hand to the ESC key and in the process accidentally touched the
Tilde key. With N1MM the tilde key turns on the SUB RX. Now in my case this
causes me to hear different stations in my right ear. But your K3 or your
N1MM configuration may have a different reaction that is causing a frequency
change.

Mike K2MK

Re: [Elecraft] K3(S) or KX3. Add function to Utility to save non-radio specific settings

[Don Wilhelm]

Kevin,

There are casual users and and there are the "geeks".  The "geeks" would 
have no problem with this proposal, but the casual user may run into 
difficulty.


If the configuration data could be separated into general and K3 
specific files, then your suggestion would be valid.


I agree that posting the configuration of each K3 (K3S) would cause a 
huge increase in Customer Support calls and emails.


The firmware load does not cost $500.  It is more likely to amount to 
the minimum charge of $99 plus shipping.

[Elecraft] PX3 question

[Stan Horzepa]

I have a KX3 and a PX3. The KX3 has all the options including the KX3-2M 
2 meter transverter. I have not used the transverter a lot because I 
have been preoccupied using the KX3 on HF.


Anyway, when I began using the PX3, I swear that it displayed the 
signals received on 2 meters, but now it does not. The firmware in the 
KX3 and PX3 is up to date. In fact, it seems that I first noticed the 
PX3's loss of 2 meter display about the time I updated the PX3 firmware 
a few weeks ago. And, yes, the PX3 still works fine on the HF bands.


Anyone have a clue what setting I might have fouled up to cause this 
problem? (Or have I lost it and the PX3 really never displayed 2 meter 
signals.)


Thanks and 73,

Stan, WA1LOU
