Re: [Elecraft] K3: KPA500 vs XYL

[Gary Gregory]

Daughter are a worry though...my daughter lives in Las Vegas, NV, and when I
told her there was a package arriving from Watsonville and to send it on to
me, she asked "what is it?", so I tolds her.

The response was I was spending her inheritance..:-(

Oh, and yep, she is licensed too

I really can't win...love'em heaps, but I am outnumbered and outgunned...or
if you insist, a wimp...:-)

Life is great though as I know my daughter will select a nice retirement
home for her Dad...minus the Elecraft K Line.

Gotta run, the nice man in the white coat is calling me.

Re: [Elecraft] K3: KPA500 vs XYL

[Kevin Luxford]

Hi Guys,

None of those XYL blandishments would work with my beloved of over 48 
years married life.  At the time we got engaged, I gave her a string of 
pearls.  She asked me, "How much did they cost?"  I should have 
recognised the warning signs then.

Several years ago, we were in Sorrento in Italy.  I took her into a 
jeweller's store and told her that as I was getting on in years, she 
could have any ring in the store (within reason) that she fancied.  She 
told me that she would rather have the money in the bank in case she had 
to put me onto a nursing home.

Still, she cares for me, she really does.  Always been at my bedside 
when coming out of an anaesthetic.  As the Brits say, "Mustn't grumble!"

Well, guys, enjoy your KPA500s.  I will just have to build mine with an 
MOT power supply and 813s or a Russian GU74b.

[Elecraft] understanding screw sizes

[Pierfrancesco Caci]

Hello,
while lenght of the screws is given in the manual in mm also, I'm
trying to figure out how to read the screw and washer diameters
that are given as "4-40" and such. Is this the relevant standard?
http://en.wikipedia.org/wiki/Unified_Thread_Standard 

For washers, the first number should be the size of the hole, right?

It's real easy Jeff. Just tell her about it over an expensive and romantic

Re: [Elecraft] New product suggestion

[David Gilbert]

I wasn't in any way suggesting that Elecraft should do such a thing.  I 
was merely trying to point out that the requests from several members of 
this list amount to not much more than that ... wrapping an Elecraft box 
and logo around already available, well-performing, and cost-effective 
commercial alternatives ... for which they would apparently be willing 
to pay premium prices.

Re: [Elecraft] Proposal for Mono-band Elecraft

[Mike Morrow]

I just wrote:

>I could be very content with a KX0-15, in my pipe dream!

One thing I should emphasize is that any viable design that would
interest me *must* utilize PIC/DDS technology, just like the KX1
and the SWL DSW.  I'm not interested in going back to *any* of
the old crystal and L-C oscillator designs for a mono-band rig
that were once so popular.  I've built a bunch of them, but the
1999 DSW rigs spoiled me for the beauty, apparent simplicity, and
operational advantages of the PIC/DDS approach for this type of
rig.

Re: [Elecraft] Proposal for Mono-band Elecraft

[Mike Morrow]

Guy quoted an excerpt from Doug:

>>>One other thing: I really wish Wayne and Eric would peal off one of
>>>their talented junior engineers and design a K0. (K zero).  A single
>>>band superhet with 2-3 watts out and super compact.
>
>What is there not super compact about a KX1?

You have asked me about someone else's (Doug's) statement.  You'll
need to ask Doug.

But I agree.  For what it'll do, the KX1 is indeed very small at 
1.2 x 5.3 x 3.0 cubic inches.  A mono-band DDS rig could be smaller.
SWL's DSW was 1.5 x 4 x 4 cubic inches, but its optional case had
a lot of extra space that could have been eliminated.  If the DSW
PCB had used more pre-assembled surface mount (like the MFJ Cub),
the package size could have been reduced much more. 

But more important than the volume figure is the simplicity, compared
to the non-simple four-band KX1, that a mono-band rig allows, particularly
if the PCB is supplied with most of the common components already
pre-assembled using surface mount components.  The alignment of a mono-band
QRP rig using PIC/DDS technology is also extremely simple.  The DSW, for
example, requires peaking only one receiver input coil for maximum noise,
and adjusting one trimmer cap to set the frequency of the BFO/product detector.
All other frequencies are generated by the DDS chip controlled by the PIC's
programming (just like the KX1).

I could be very content with a KX0-15, in my pipe dream!  (No, I don't
actually expect that there will ever be such a thing.)

Re: [Elecraft] New product suggestion

Heh, heh OK, great. You've convinced me of the desirability of
having as many extra boxes and cables in my shack as possible. That is
really what ham radio is about. So now I'll suggest that Elecraft
redesign VFO-B as an outboard box with five or six cables to attach to
the K3. Maybe add a big outboard knifeswitch for power on/off and a
standalone Jacobs ladder for the benefit of those too technologically
jaded to be impressed by a mere tangle of wires and jumble of boxes.

Re: [Elecraft] New product suggestion

  Dave,

Selling re-branded items is a "bag of worms" in many cases.  The 
re-brander must take full responsibility for any warranty issues, and 
the re-brander is at the mercy of the originator for providing a quality 
product that meets specifications.

There has been enough discussion about the Elecraft USB to serial 
adapter ( the previous Prolific adapter) that everyone should heed - 
let's not pass that same legacy on to power supplies.  Some things are 
outside the control of Elecraft and the subtleties of "specmanship" may 
miss the eyes of even the most conscientious engineer.  I cling to the 
KISS principle - let each manufacturer be responsible for his own 
product.  The integration of other manufacturer's product (like the K3) 
should be done first on the specifications, and secondly on endorsements 
of other manufacturer's products..

Re: [Elecraft] New product suggestion

[Gary Gregory]

PowerWerX Model number SS-30DV is a switch mode, 30A very small supply and I
have 2 of them here and NO RFI issues, stable at 13.8VDC.

It even has a very silent fan plus Anderson plugs (2) on the front with Lugs

At our mountain top locations, we have been using the various current 
capacity models of the supplies from 
http://www.iotaengineering.com/dls.htm  and have found them to be 
excellent for many years of service.  We use them to float charge LARGE 
battery banks at 12 VDC.  They provide tremendous capability in a very 
small, highly efficient package.

The 70 Ampere units have been extremely good for float charging 2,000 + Amp 
Hour battery banks.

  Vic is right, scope probes have a peak voltage rating associated with

Re: [Elecraft] using a scope on a k2

[Vic K2VCO]

Be careful if it's a K2/100. Probe ratings decrease with frequency, and the 
voltage
applied to the usual scope probe with 100w going into a 50-ohm load at 28 mHz 
will blow
the 10x attenuator in probe. I don't need to tell you how I know this!

Re: [Elecraft] using a scope on a k2

[Don Wilhelm]

  John,

I have to condition my answer on this one because I do not know what 
kind of  'scope you have available.

If it has a sufficiently high frequency response (3 times the frequency 
of the RF to be measured), and it has a 10X probe with it, then the 
procedure is easy - just connect the 10X probe across your dummy load.
If your dummy load does not have easy access to connect the 'scope 
probe, use a Tee adapter at the dummy load end to gain access to the 
center conductor.

If you do not have a modern 'scope with adequate frequency response, 
contact me off-list and I may be able to dredge some old information out 
to enable you to do the same thing - it is somewhere in my ole references.

CW:
Set the sweep rate to something slow matching your keying rate (key the 
TX with a string of dots), and observe the RF waveform.  If it has sharp 
transitions, that is an indicator of potential keyclicks.  Look at the 
'scope traces shown in the Elecraft K2 Keying Waveform Mod instructions 
for an example of what to look for.

For SSB:
Set up about the same as for CW (the sweep rate will be at an audio 
rate).  You will have to review some of the waveforms in the ARRL 
Handbook to see what clipping looks like before being able to judge the 
waveforms.  For amplitude, compare the peak of the audio wave to what is 
obtained in CW mode - and that level will represent your PEP.

Note that you will not actually be able to observe splatter with the 
'scope, that takes a Spectrum Analyzer - if the waveform shows clipping 
(abrupt transitions at the peaks), that is an indicator that splatter is 
occurring, but the 'scope will not show it directly.

Re: [Elecraft] Oops K1 Dead!

[Don Wilhelm]

  Joe,

Assuming you were correct that the K1 failed due to a high SWR on the 
antenna, then the most likely component to fail is diode D19.
Try lifting one end of D19 and operate the K1 into a dummy load to see 
if it still works OK.  If so, replace the zener diode.

That diode is there specifically to break into conduction in the 
presence of excessive RF voltage (caused by a high SWR).  Sometimes it 
just breaks over and does not fail, but in extreme cases, it sacrifices 
itself to save the rest of the K1.

Re: [Elecraft] KX1 - Power Amplifier Q6 Installation Question

[Don Wilhelm]

  Barry,

Yes, this is sometimes a problem - in all cases, the lockwasher between 
the spacer and the board must be present to make the standoff the 
correct height.  I have omitted the second lockwasher in some cases, and 
in others, I have used already compressed lockwashers that have been 
laying on my workbench.  Your technique of squashing the lockwashers 
with vise-grips was a good one  I am glad you were ultimately successful.

Re: [Elecraft] KX1 Red Display Filter

[Don Wilhelm]

Sorry all, I fumble-fingered the SEND button.

Sorry about the tape Chuck.  Actually, you can use anything that will 
stick it down.  If you use RTV, be careful that it does not creep into 
the display window (actually that is a good method, but not without 
hazard).  Duct tape will work, but it does harden with age.  Scotch 
transparent tape actually works quite well - get enough of the adhesive 
surface on the metal and it will stick for a long time.
Other glues that will work well are found as "Glass and Bead Glue" in 
craft stores - the same cautions as for the RTV apply.

In other words, just "get it stuck on" with a glue that will last and 
not make a mess.  Whatever is chosen must adhere to both plastic and metal.

[Elecraft] Very cool propagation site

[Tony Estep]

Lately there have been strong and long-lasting openings on all bands, as I'm
sure you've all noticed. It revives everybody's interest in propagation,
seemingly a perfect app for a PC. However, propagation programs are
expensive and have a big learning curve. Here's a website that embodies
up-to-date data and uses excellent algorithms to make propagation estimates
for the present moment or for any future time/date you choose. Check it
out:

http://www.voacap.com/coverage.html

As I write this, it shows that with 100W and a dipole, practically the whole
world is open from my qth, and indeed I can hear signals from every
continent right now. Maybe some of the old mojo is coming back.

That's it Phil.  The obvious solution to the problem is to build them

Re: [Elecraft] New product suggestion

[Eric Champine]

Hey John.
Good idea :-) I like concrete.
I see what they are talking about.
I also have a Yaesu 897D with an attached tuner and a power supply.
It is a very nice and portable package that I take up to my camp with me.
When I get to camp all I have to do is plug in the antenna and the power
cord.
My camp is small so less is better.
That is why I was suggesting something similar for the K2 and K3.
I know I would make good use of it.
Sorry if you don't like it but it may not be for you.
Portably and quality is a big reason why I am switching to Elecraft and to
have a PS in the rig its self would be awesome for me and it sounds like
others would like it too.
Just a suggestion for the "New Product Suggestion" thread.

Re: [Elecraft] K2: KSB2 Questions

[Don Wilhelm]

  Paul,

I just got back from three days vacation, and found 226 emails on the 
reflector!  I finally waded through them and will attempt to answer a 
few, including yours.

First, how to connect to the microphone configuration header - if you 
are wiring it for the Elecraft configuration, just use computer jumpers, 
all pins are connected "straight across"
But, you said you were using an ICOM mic which is wired differently, so 
you have two choices, (1) rewire the microphone plug to match the 
Elecraft configuration, and tape over the Icom label so you remember it 
was changed (I recommend that because the microphone can then be used on 
the K3, and any Elecraft microphone can be used with the K2).  (2) Leave 
the microphone plug as it is and wire the K2 mic configuration header 
for the Icom pinout.  The best way to do that is using wire-wrap (if you 
have the tool and wire), and the second best is soldering wires between 
the correct pins.  There is no plug for this connector, the header is 
designed to be wired directly.  The only downside of soldering is that 
one cannot remove the soldered wires and go back to using the 
computer-type jumpers.

Solder the bias resistor on the back of the microphone jack rather than 
trying to connect it at the configuration header.  A value from 5.6k to 
10k will work fine for most electret mics like the Icom and the Elecraft 
mics.  one end of the resistor connects to the 5 volt mic jack pin and 
the other end connects to the AF pin.

Yes, that bias resistor MAY cause some problems with the soundcard 
line-out for SOME soundcards.  It would be wise to put a DC Blocking 
capacitor in the AF line of whatever soundcard interface you may use if 
there is not one there already.

Re: [Elecraft] New product suggestion

[John Ragle]

One could build a resistive load into the box, thereby avoiding the 
antenna coax. Also, one could disconnect the microphone and remove all 
the knobs, etc. from the front panel! How about just potting the whole 
thing in concrete?

Re: [Elecraft] KAT500

[Geoffrey Mackenzie-Kennedy]

Indeed, being able to talk to a remote tuner without adding extra control
lines is desireable and can be achieved.

One method, which I used in a 1950s vintage homemade link coupled remote
tuner, makes use of "frequency sensitive" relays in the remote tuner to
control the tuner's band switching tasks, along with a simple servo
arrangement which tunes the motor driven variable capacitors for minimum SWR
as seen at the coax's connection to the link circuit during Tune.

Although the DC power required could be fed via the coax, I opted to use a
separate cable.

I believe that because the ICs used to generate audio tones and to decode
audio tones are so inexpensive these days, controlling remote devices by
means of audio tones sent down the coax feeder might be a better option.

The use of Fibre Optic in lieu of copper to carry multiple control tones is
an option I have been pondering for use in the future, but probably too
expensive for a commercial product.

I'd like also use the KPA500 with my K2...does anybody know, how much output
power is available ?

13dB Gain...10W IN, 160-200W OUT ?

Re: [Elecraft] New product suggestion

[Eric Champine]

Hi all.
I like the PS idea for both the K2 and K3.
What I was thinking is that there is no space inside both of the cases with
options installed but if they could design a screw on bottom section with
the PS in there. Yaesu has something like that and it is only around a inch
tall when added with no fan and runs cool at 100 watt's. I don't see why a
small housing couldn't be manufactured to bolt on to the bottom.
I don't know about the K3 but the K2 looks like it could be done.
Just a thought.

What is there not super compact about a KX1?  A double pack of
Twinkies is bigger than a KX1.  It's the same size as four Milky Way
candy bars.  For some reason all the things I can think of to compare
size with are small and taste good.

It's almost small enough to strap to your wrist.  (Anybody here old
enough besides me to remember Dick Tracy?)

Re: [Elecraft] New product suggestion

[drewko]

Still raining...

I wonder if a small switching supply module could be designed into the
space occupied by the PA, and having a standard line cord on the back
panel of the module. Just for us low-power K3'ers. I'd sure like to
have one. I guess it depends on the potential market size (How many
non-PA K3's are there in circulation anyway?)

Actually, if you move them apart a little bit and place them on a window sill 
during the day you should be able to look at them and see daylight between them.

I have been reviewing the differences as much as I can between the KX1 and the 
K1 --- obviously they are different but I agree not so much that someone would 
make a mistake by buying the wrong one.  Having said that, I am so afraid of 
making mistakes that I am buying both.  I already have and completed the KX1 
kit with the 80/30 option.  I am going to order the K1 as soon as I get a 
window of opportunity to put it together.  After I get the K1 finished and get 
it on the air, I will be able to sleep better at night.  Well, sleep a little 
better until the hankering for the K2 gets up to serious levels.  I already 
have the K3, the P3 and sometime this year the KPA500 (got to buy my wife a new 
camera first and that will cost as much as  the KPA500).

Re: [Elecraft] New product suggestion

[Guy Olinger K2AV]

Just in case you haven't looked, the inside of a K3 is filled up if
you have the 2nd RX and the 100W KPA100.  IF they could put a 25 watt
PA and a power supply in the same space as the KPA100, you could use
the KPA500 if you wanted more than 25 watts.

Or, all you folks that got P3's, any room in the back of the P3 for a
power supply?

Re: [Elecraft] New product suggestion

Cold and rainy here, also...

Actually, I would love to have such a P/S built into my base K3. (Yes,
the K3 is very light and portable; except not so much when you have to
bother with PS, cables and cord). 

With a built-in PS you wouldn't need any meters or box and could use a
standard line cord instead of cables, APP connectors, etc. (Would
require a new back panel for the K3, i guess...) This would be more
convenient to transport, even for just around the house when you'd

Re: [Elecraft] Proposal for Mono-band Elecraft

[Doug Person]

There are not many choices that are actually available.  And some (most) 
vendors provide no support.  I just built a 40 meter qrp cw 
transceiver.  It was missing parts which took 4 weeks to get; the 
instructions were poor and incorrect;  the rx performance was marginal 
and tx only put out half of its specified power  So, pretty much how 
things were before Elecraft.  And, I agree.  A 10 meter rig would be nice.

Re: [Elecraft] Proposal for Mono-band Elecraft

There are several monoband choices available already, but what I
haven't found is one for 10m.  With the sunspot cycle on the rise,
this would be a very desirable rig, and possibly the only source for
one on that band.  And by all means, make it a 4-pole crystal filter.

[Elecraft] using a scope on a k2

[John Cooper]

How would I use a scope to monitor key clicks on cw, and the waveform on ssb?  
Also anything else I can do with a scope too?  This is in reference to a K2  IE 
where do the probes go and so forth.  Off list is fine too.  Couldn’t find any

[Elecraft] KAT500

[Mike Fatchett]

There has been much speculation and suggestions for this new product.  I 
am sure the Elecraft team will produce another fine product.  I doubt 
they would be working on this product unless they felt that they could 
improve upon what is already available on the market.  I have a couple 
of LDG tuners and they work very well.  The issue I have with their 
tuners is that the power handling capabilities are halved on 6m.

One of the design requirements for the new KAT500 is that it will handle 
the full output of the KPA500 on all bands.

I would like to see multiple antenna inputs for the tuner and a way to 
specify which one is used on which band.

A number of people have suggested a weatherproof unit for placement 
directly at the antenna feed.  In this setup extra inputs might be 
wasted unless you ran your other feeds over to the tuner.  Talking to 
the remote tuner without extra control lines might be a challenge.

A wattmeter and SWR meter should probably be part of the unit.

I will be curious to see what the enclosure will be as I hope to take 
one to J6 in November.  I am not sure that the tuner could be made much 
smaller than the K3 enclosure.  Using the same enclosure is cheaper in 
the long run and matches the the K-line ascetically.

It is refreshing to be able to exchange ideas so freely with the 
manufacturer and actually receive prompt feedback!

Thanks Elecraft!  It is a pleasure doing business with you and it is a 
pleasure using your products!

Re: [Elecraft] [K2] What happens above 28.8 MHz ?

[Geoffrey Mackenzie-Kennedy]

Steve,

I have not measured the roll-off of the the K2's bandpass and low pass 
filters above 28.8 MHz, and I cannot help you at the moment because I do not 
have my test equipment here..

My K2/100's receiver did have a couple of fairly strong birdies near the top 
end of ten, which IIRC were due to some harmonic of the BFO being heard by 
the desired response or a spurious response of the receiver e.g. BFO x 6 = 
approx 29.479 MHz in my K2.

[Elecraft] KX1 tuning

[Chris Fowler]

I am a bit confused with the power reported when tuning the KX1.

Today I used a Maldol whip.  While tuning the rug reported power of 6 with an 
SWR of 4.  I had no luck do I went to my car with a ham stick.  With that 
antenna was getting a power of 0.8 abc SWR of 4.   So why is this?  The power 
does not really matter since neither yielded QSOs.  I am just curious as to how 
this works.

I have much better antennas.  I am on vacation and my options are severely 
limited.

I believe I may have blown Q7, the PA. When I measure the resistance with it

this sound like the PA is gone?

[Elecraft] New product suggestion

[Paul Huff]

There's not much activity on the bands right now so I'm just sitting here on a 
cold rainy day fantasizing about nice weather, lottery winnings, and new ham 
gear...

Something that I would like to see as a new Elecraft product would be a basic 
12-volt power supply.  Specifically a switching power supply with no RF 
interference problems, simple metering (analog or digital) to monitor voltage 
and current, and a box that matches current Elecraft rigs.  I'm strictly a QRP 
guy so something small would keep me happy, but a little more beef for the QRO 
people would be OK too.

Now, what will I do with that million dollar lottery prize? ...

[Elecraft] K-Tuner recommendation

I'd love to see the new Elecraft Antenna Tuner have provision to do  
automatic band selection of 4 or more unbalanced feedlines like the Yaesu

[Elecraft] Proposal for Mono-band Elecraft

[Mike Morrow]

Doug wrote:

>their talented junior engineers and design a K0. (K zero).  A single 
>band superhet with 2-3 watts out and super compact.

So...maybe a K0-15 for 15 meters.  I like that concept.

Before the K1 became available in 2000, I had built three of Dave Benson's
Small Wonder Labs DSW series of mono-band PIC- and DDS-technology QRP rigs.
I still have the DSW-20, -30, and -40 and they remain great and very
innovative QRP transceivers.  Wonderful rigs!

My only issue with those $130 (in 1999) units was that the operating system
allowed ONLY iambic mode B keying, which I consider an abomination. :-)
However, Jackson Harbor Press produced a direct plug-in replacement PIC
(controller) for $7 (!!) called the DSWK that offered many additional
features over the original SWL PIC, including selectable iambic keying
mode (just like Elecraft).

The DSW (and later DSW-II) with the DSWK PIC created what is IMHO still 
the neatest small mono-band QRP rig of all time.  Unfortunately, Dave
discontinued the DSW series several years ago, leaving that market empty.
I regret not having purchased a DSW-II-80 when it was available.

Today I almost always use the K1, but sometimes I will take one of the DSWs
when I just want a very small mono-band set.

Elecraft advanced the PIC/DDS concept to the multi-band feature-rich KX1 all
in a small package, yet I also believe there's still something appealing about
a smaller, simpler, mono-band rig.  A new Elecraft rig that combined some
characteristics of the SWL DSW-II and the (don't laugh) MFJ Cub would be great.
The DSW characteristic would mean a rig that needed NO LED or LCD display.  All
control response output would be Morse.  The MFJ Cub characteristic would mean
a rig with all the "boring drudgery" components being machine pre-assembled
surface-mounted to the PCB.  Only a few major components that mostly determine
the operating frequency would be required to be hand assembled by the builder.
Such a rig could be put together in an evening while encountering much less
opportunity for construction error.  (There'd be much less demand on Elecraft
tech support for troubleshooting.)  Choose a DDS chip that can be clocked
high enough to allow a 15m model, use a four-pole IF filter, and provide an
AGC circuit.  Mono-band CW perfection!

I'd buy a couple, maybe more.

Re: [Elecraft] UFER Ground In House

[Byron Servies]

Hi,

I am currently installing a new ground system and when I had an
electrician out to talk about my plans, he thought it would be best to
connect a wire to one of the available ports in the service panel
ground bus rather than connected it to my UFER ground.  On my panel,
this bus is covered by the metal of the panel itself, all of which
needed to be removed to inspect possible connection points.

As mentioned in the 2010 ARRL Handbook, this connection should be done
by a licensed electrician, probably because everything needs to be
open and the utility company feed exposed when this work is done.
Still, it is advice I plan on following as I finish up in the next few
weeks.

Also note that there should be an inspection port somewhere (for
new-ish construction. My place is in CA and built in 1992) where the
inspector can view the UFER connection; mine is very near the service
panel on the inside of the garage covered with a blank single gang
outlet panel.

Odd note: my UFER ground must have been insufficient because there are
2 lengths of rebar bent near each other and clamped together. My
electrician said he had never seen 2 used before.

[Elecraft] Oops K1 Dead!

[af6ni]

I am not the builder of the K1, so I am not familiar with the circuit. I do
have the original manual however.
This morning I  was testing an antenna and I think I let the SWR get too
high. Result - the K1 is now completely dead and it appears as if my 12V
supply has a dead short across it when I try to power up the K1.
Any suggestions on where to start looking is gratefully appreciated.
Thanks and 73,
Joe

[Elecraft] UFER Ground In House

[goldtr8]

l the talk about grounding had me looking at my house to figure out how 
I was going to tie my antenna grounding together with the house ground 
correctly.

I was not able to find an external ground rod and was confused until 
someone mentioned the UFER Ground.

So my question is can anyone point me in the proper direction on how to

Sounds like KPA3 is disabled in the config menu. It should be set to PA NOR if 
you've got the 100 W amp.

[Elecraft] K3 feature request, DUAL PB, VFO A-B independence

[Mike K2MK]

Chasing a rare one operating split on RTTY, I will use the SUB RX and two
MMTTY windows so that I can see what's going on up in frequency. I'll have
the bandwidth narrow on VFO A and wide on the SUB RX. Sometimes I'll hunt
for a clear spot and sometimes I'll hunt for the station being worked.

Occasionally I will turn on the Dual PB to help copy the DX station.
Unfortunately this also causes the SUB to go into DPB. If I go into BSet and
turn off the DPB it also turns it off in VFO A. So obviously there is no VFO
independence for the DPB feature. 

I would like to request that the DPB feature have VFO independence.

73,
Mike K2MK

You can calibrate your rx within 1 hz using the technique desribed in the
manual, then just read the test frequency off your dial. Several WSPR users
were among the top finishers in the last test using this technique.

When you first read it, it sounds harder than it is. You just calibrate at
several different reference frequencies, then generate a correction function
for dial error vs. frequency. If you like this sort of stuff, check it out.

Re: [Elecraft] K1 #2973 on the Air (Choosing the K1 or KX1)

[Andrew Moore]

(KK5F review of K1 and KX1)

Great and thorough review Mike.  I'll add some opinions:

- KBT1 battery option is a little fiddly and I found that swapping batteries
was cumbersome.

- With no KBT1 installed, even with KAT1 installed, a nice feature of the K1
is that there's room inside for custom expansion, or for just working on the
rig.  I always liked the clean, open layout of the K1.

- In terms of quick setup time (and the obvious size/weight advantages), the
KX1 is the best I've found. Battery swaps were also fairly quick and
painless.

Indeed.  The biggest losses generally occur with attempts to match low 
impedance antennas. That usually means trying to match an electrically 
short antenna.  I suspect that is pretty common application.  Having the 
tuner remote eliminates most of the feedline loss but not this impedance 
matching loss.

Personally I'm not interested in having 100 -150 watts (out of the KPA's 
500) disappear as heat in the tuner.

I'd wait and see how the KAT-3 stacks up loss wise for the type of 
antenna situation you have.

Re: [Elecraft] K3 Factory Reset?

[Bill W4ZV]

If you simply want to restore default CONFIG menu settings without doing a
full recalibration, tap DISP (to the upper left of the LCD) while in each
CONFIG menu, and you'll see the default setting appear momentarily in the
VFO B display.

If it were me I would do EE INIT and a complete recalibration, but you
should review the Calibration section of the manual first so you know what
you're getting into.  I'd also check to see which hardware updates have been
performed since #281 is a fairly old unit and I'm guessing a dozen updates
would apply.

Checkout Fldigi:

http://www.w1hkj.com/Fldigi.html

It is a Freq Analysis mode that will output recorded frequency error to
a CSV file that can be imported into a spreadsheet and massaged as
needed.  After that the options become more expensive.

Re: [Elecraft] ARRL FMT April 13 - 0215utc (K3EXREF)

[Bruce Beford]

Hi, Ed. Here's a group that I belong to:

http://groups.yahoo.com/group/FMT-nuts/

 

Many of the members there are true time/freq measuring nuts. The Midwest
VHF/UHF society run their own FMTs at different times of the year. You can
also Google time-nuts. If you don't mind a simplistic overview, the audio
output of the radio is sent to the sound card of the PC. One uses an audio
analysis program like Spectrum Lab or Spectran to analyze the frequency of a
beat note. Sometimes that is just watching the carrier of WWV while in CW
mode, sometimes a very accurate signal generator is also input to the RX at
the same time as the signal under test, and the difference measured.

 

Doing the FMT can be a great challenge and a lot of fun. However, getting
really good at it can take some work (which is part of the fun). Often
times, ones measurements are limited by the Doppler shift of the ionosphere
(yes, there is Doppler even at HF). In the finally analysis, one sometimes
has to resort to "guessiplication" for deciding what frequency to submit as
your measurement.

 

All that said, on one of the FMTs done a year or so ago, I was able to get
within 9 milliHertz of actual carrier frequency on a 20M test out of the
Midwest. I used an HPSDR Mercury DDC receiver that was phase locked to a
Trimble Thunderbolt GPSDO. That's about 6 parts per ten trillion. And I
wasn't even the closest...

Re: [Elecraft] K3 Factory Reset?

[David Windisch]

It ain't always this easy for this dinosaur to find . Brgds, dave, N3HE

From P. 66 of the on-line manual: 

Parameter Initialization
Menu parameters are stored in non-volatile memory (EEPROM and/or FLASH). It
is possible, though rare, for
parameters to become altered in such a way as to prevent the firmware from
running correctly. If you suspect
this, you can reinitialize parameters to defaults, then restore a
previously-saved configuration (or re-do all
configuration steps manually; no test equipment is required).
• If you have a computer available to do configuration save and restore, run
the K3 Utility program, then use
the Configuration function to save your present firmware configuration.
• If you don’t have access to a computer, you should write down your menu
parameter settings. The most
important are CONFIG:FLx BW and CONFIG:FLx FRQ (for each installed filter ,
also tap SUB to
obtain sub receiver crystal filter settings, if applicable). You should also
note the settings of option module
enables (all CONFIG menu entries starting with ‘K’, e.g. CONFIG:KAT3) . If
you don’t record your crystal
filter and option settings, you may have to remove the K3’s top cover (and
sub receiver, if installed) to
verify which options as well as crystals filters are installed, as well as
the frequency offsets noted on the
crystal filters (depends on filter type).
• Turn the K3 OFF (using the K3’s POWER switch, not your power supply).
• While holding in the SHIFT/LO knob (which is also labeled NORM below),
turn power ON by tapping the
K3’s POWER switch. Let go of the SHIFT/LO knob after about 2 seconds. You
should now see EE INIT
on the LCD.
• When EE INIT completes after a few seconds, you may see ERR PL1 or other
error messages due to
initialization. Tap DISP to clear each message.
• If you have a computer, restore all parameters using the Configuration
function of the K3 Utility program.
• If you don’t have a computer, manually re-enter all menu parameters that
you wrote down, above, then redo
firmware configuration and calibration (starting on pg. 46). You can omit
any steps pertaining to
parameters you’ve already restored manually.
• See if the original problem has been resolved.

Re: [Elecraft] K1 #2973 on the Air (Choosing the K1 or KX1)

[Jessie Oberreuter]

  Totally agree!  I love my K1, K2, and K3, but the SST is something 
special -- it transports me back to childhood nights tuning through the 
static, looking for an echo.  It puts out a solid 2w, which is enough umph 
for a good conversation, and the fact that it simply drops the rx gain 
during xmit not only means you're monitoring your own tx and getting a 
perfect side-tone, but also that you can operate full duplex!  I've not 
only copied between the dits -- I've copied through them :).  The K1 is my 
standard travel radio, but if I'm going somewhere special, I'll take the 
SST and a miniature straight-key instead, and re-live the magic!  A BLT in 
its nearly matching aluminium case makes a great companion tuner :).

Re: [Elecraft] re KPA 500 and ATU

Come on, putting a 500 W PA into such a small enclosure is already an
incredible achievement in itself (congrats, Elecrafters!) and a matching ATU
cannot be built with miniature, surface-mounted type components, can it?
Let's stay realistic. If Elecraft is really going to offer the ATU in a
P3-sized case, that will be yet another first in the industry. I'm looking
forward to building and enjoying my KPA500, not trying to further improve it
before it's there!
