I don?t have a KX3, but a friend does and he has a question regarding the KX3 receiver in a multi transmitter environment like Field Day.  I would not expect it to be as good as a K3, but is it usable?  Anything special you have to do to it?  I?m thinking at a minimum a set of band filters, which would be easy even with the 100 watt amp.

Thanks for your thoughts and experiences.

If you get the model with the roofing filters, it is actually a better
receiver than the k3 in a multi transmitter environment. With good antenna
separation you can run a k3 on the cw portion of the band and another on
the ssb portion without an issue.

Subject: [Elecraft] loss of receive audio on K3
Message-ID: <CA+u=Ds2MyhUMCYTwL_aq=JonTdiMVn=9mMs9+v7vc4=sQYetpQ@mail.gmail.com>

 I had the strangest thing happenyesterday (K3, 1st prod run).

All of a sudden, I lost all audio output (headphones).  I pull the
headphones, but same thing on the internal spkr.  Radio was tuning,
receiving (per P3) and transmitting, but zero AF output.

After 15 seconds of wonder, I turned the K3off, waited 30 seconds and
turned it back on.  All was back to normal.

At one point, I heard a low rumble, like someone strong was tuning up on
me.  But no.  That immediately preceded the loss of AF.

After I turned it back on, after another 5-10 minutes, I again heard the
low rumble..but nobody tuning up on me...and this time, no loss of AF.

Again that same rumble happened again, but that time the AF went to about
50% but then came back after I transmitted a dit (just dumb luck timing?).

Have you heard any stories like this before or is this a novel experience?

Thanks

In my book, there are too many variables in any given installation to rely 100% on any "standard" convention, including modeling.

When I built my Extended Double Zepp (a 360 foot long, 1.25 wavelength center fed dipole) with a design frequency of 3.5 MHz (and approx. 5 db gain), I measured the impedance at the "shack end" of the feedline (160 feet of 600 ohm OWL from https://www.trueladderline.com/ ) at multiple points on each band.  Actual readings ranged from 323 ohms at 1840 KHz, 536 ohms at 3573 KHz, 598 ohms at 5357 KHz, 249 ohms at 7074 KHz, 371 ohms at 10136 KHz, 344 ohms at 14074 KHz, 260 ohms at 18100 KHz, 50 ohms at 21074 KHz, 182 ohms at 24915 KHz and 142 ohms at 28074 KHz (note tuner runs in 'bypass' mode on 15 meters where it is roughly 7.5 wavelengths).

I'm, feeding that thru a hybrid balun which is 4:1 on the antenna side, and 1:1 on the shack end (Balun Designs #4116-T).  Approximately 15 ft of RG-8x runs from the balun to the KAT500.

The KAT500 gives me a 1.00 match on all those frequencies (standard FT8 frequencies) and generally less than 1.5:1 at any point on all bands 160 thru 10 meters whether I'm running 10 watts or 500 watts. 

The weak spot in the chain is the KPA500 which will not allow the KAT500 to tune properly if the amp is in "Operate" mode (it did when it was new, but that's another issue).

Every installation is different, but this combination works as well for me as I could hope and results bear that out.

I don't understand the use of the 4:1 balun.  On 80M the feed Z of that 
antenna is more likely 25 to 50 ohms.  The 4:1 balun would present a 
impedance to the RG-213 of 6.5 to 12.5 ohms.  You would be much better 
with a 1:1 balun configuration.  Remember one is not matching the feed 
line impedance but is matching the antenna impedance.

The ideal use of a 4:1 balun is with a folded dipole antenna which 
presents a 200 to 300 ohm impedance.  Now the feed line Z is much closer 
matched and the 4:1 balun gets the Z to the coax in the 50 to 75 ohm 
range.  Much more efficient.  This of course is a single band antenna.

See https://www.dj0ip.de/balun-stuff/  for good, accurate, and reliable 
information on baluns and their usage.  Most hams have it wrong as well 
as most manufactures of antenna tuners who include a 4:1 balun.

7.280, every Sunday.
Greetings from NW GA.  Band was in pretty good shape and very little QRM
from contesters.  Keep in mind that the time change takes effect next
week.  All of the Elecraft SSB nets remain at the same GMT time.  The 40
meter net time remains at 1900Z.
Thanks to all my relay stations and check-ins.

I have some observations and/or questions

First I think you could model this.

Second, how did you measure these impedances?? You quote them as resistive, are 
they?

Is that 5 dB gain in a useful direction? What about the other bands?

Message-ID: <715B9423-13FD-441E-AC5E-95877A152D4E@elecraft.com>

I took advantage of the excellent conditions today to work a little DX with the KX2. I was running 10 watts on 17 meters to a 20 meter vertical.

There was HD8M (Galapagos), loud and clear, calling CQ "up 5" on 18.145. 

When I broke the pileup on the third call, I reflected on how many of the KX2's features came into play to make this happen:

  - ATU easily matched my 20 meter vertical on 17 meters (1.0:1)

  - internal battery allowed transmit at a full 10 watts

  - speech compression made it sound more like 20 or 30 watts :)

  - used the KX2's stereo audio/dual-receive function to listen on both 
    18.145 (RX) and 18.150 (TX) at the same time; transmitting SPLIT

  - annoying S8 noise pulses were vanquished by the NB

  - carriers from the inconsiderate were dealt with by auto-notch

  - used one of the rig's two DVR messages to do the calling

That's a lot of fully integrated fun in a radio that weighs less than one pound and draws only about 170 mA in receive mode. And a great excuse to get outdoors.

Details on the KX2 can be found here:

Hi Wes -

Yes, you could model this ... and I did do that first to get a gut check on the concept.  But as I said, I don't rely 100% on the modeling.  I want to see real world measurements.  I used an antenna analyzer to read the impedance (comprised of resistance, inductive reactance and capacitive reactive).  Those are the figures quoted.

The gain on 80 meters is right where I want it, in a N-S pattern.  My purpose in building it for 3.5 MHz N-S was to put the best possible NVIS signal into our state capital (Springfield, IL) on 80 meters for EmComm purposes.  It does that job very nicely, and I find myself able to do so when others around me are having difficulty.

It has decidedly different patterns on other bands, but none are particularly objectionable.  If you'd like to see the plots, as imaged by EZ-NEC, they're on my QRZ page (scroll down).

In the 2 years it's been up, I have logged 131 contacts in your area - Tucson - on 160, 80, 60, 40, 30, 20, 17, 15 and 12 meters.  

It's the only antenna I have, and it works well.

73
Lyn, W0LEN

I assume your using a balun with your

Hello Elecraft List

I have no microphone for my K3. I am usually on CW or the digital modes.
Now I want to get on the KY Phone Net on 3838.

So I talked DXEngineering and they know of no adapter plug/cable.

So, I have an Icom SM-50 mic  and a Yaesu MD-100 mic.

Anyone know of an adapter connector that would fit either to adapt them to the K3?
Or maybe a universal box that lets me plug all the mic's in and have a cable to the K3 ....
Also run an Icom IC-9700 FWIW.

thanks!

Those RF chokes are bi-lateral - they can be installed either way, just 
like resistors.

Some folks, for esthetics usually, put chokes and resistors in only one direction throughout the build, which may simplify finding mistakes later, the numbers or color code direction is always the same.

Pretty is only relevant to the builder hi hi.

A common mode choke (not really a balun) at a point of high SWR can heat 
up and as it does so everything drifts, making tuning impossible.? Been 
there, done that using high power to a 160m Inverted-L that was close to 
resonant, but due to expediency was fed at a point of high SWR.? A 
relayout of the antenna to lower the SWR fixed everything using the same 
choke (which luckily hadn't been permanently damaged).

You will have to either rewire the Icom mic's Foster plug or you need to

Anyone know of an adapter connector that would fit either to adapt them to

Or maybe a universal box that lets me plug all the mic's in and have a cable

Also run an Icom IC-9700 FWIW.

NO! The problem was that by their nature, OCF antennas are BADLY 
unbalanced, placing very high stress on a common mode choke, so are 
likely to fry ANY common mode choke that does anything useful.

Study k9yc.com/RFI-Ham.pdf

AND -- erase the word "balun" from your vocabulary. It is used to 
describe almost a dozen very different things, obscuring understanding 
of how things work.

Don't stay stuck in the past: not all ocf dipoles are created equal. 
With properly designed transformers and chokes, the common mode current can be tamed to perfectly decent levels.

I suspect you don't understand the physics of the problem. OCF antennas 
are a yesterday's approach to multiband antennas. They are a recipe for 
RX noise and RF in the shack. The concept was developed decades ago, 
when there was far less noise than there is today. It's possible to fool 
yourself that it's working fine, but you can't hear very well, so you 
miss stations calling you.

I run legal limit on FT8 for weak signal work on 6M and difficult paths 
on 160M (EU from California) into resonant antennas that are choked and 
fed with RG8 or RG11, and I regularly get signal reports 15-20 dB worse 
than I give. Since signal reports on FT8 are signal to noise, that means 
the other station can't hear.

Jim?? 
First?.. what length is your OCFD ?
2nd??   What Height above ground ?
3rd??   What Feed line are you using ?
4th ??   What Band do you Operate on Most ?
I can Model the Antenna and give you the results .

Hi Jim

Not many folks have the space or ability to put up a full set of resonant dipoles.  The MODERN off centre fed dipole is as good as you'll get any multiband antenna and for the most part will not need a separate antenna match box.  

I suggest you measure the common mode current on a decent ocf dipole and see for yourself. Great progress has been made in the last few years and, yes I use your cookbook.

It appears that MFJ makes a box, designed to convert one brand?s mic connector to others.  It appears to be programmable, using jumpers.  

I believe the Foster connectors on the K3 or K3S are wired the same as Kenwood?s.

The model number is MFJ 1263.  I have not used or seen one, so cannot comment on its utility.

I have no microphone for my K3. I am usually on CW or the digital modes.
Now I want to get on the KY Phone Net on 3838.

So I talked DXEngineering and they know of no adapter plug/cable.

So, I have an Icom SM-50 mic  and a Yaesu MD-100 mic.

Anyone know of an adapter connector that would fit either to adapt them to the K3?
Or maybe a universal box that lets me plug all the mic's in and have a cable to the K3 ....
Also run an Icom IC-9700 FWIW.

Bob,

The Elecraft mic pinout is ALMOST the same as Kenwood's
The Elecraft pin 6 carries +5 volts while for Kenwood, the +5 volts is 
on pin 5.
Pin 5 for Elecraft is the Function button.

If your microphone does not require +5 volts and does not have buttons 
other than PTT, then you only have to be concerned about pin 1 (AF), pin 
2 (PTT) and pins 7 and 8 (one for PTT return and the other for AF return 
- both are connected together inside the K3).

Icom and Yaesu are not as straightforward, see the G4WPW info at 
https://www.qsl.net/g4wpw/date.html for details on the pinout for those 
mics.

If you can do a bit of soldering, you can make and adapter for the price 
of a male and female Foster connector and a bit of wire.? If you rewire 
the Foster connector on the mic, you don't need any adapter or 
connectors at all, just a bit of solder, to unsolder the wires from the 
existing connector and solder them in the correct pins for the K3.

OTOH, if you wish to switch back and forth between the Icom/Yaesu pinout 
and the Elecraft, the adapter or the MFJ box would be the best choice.

Or... you can use the standard stereo mini plug which is usually 
supplied with condenser mikes and plug into the mic jack on the rear of 
the K3.? I use a Yamaha CM550 and it plugged directly into my K3 - just 
had to remember to enable bias on the rear mike jack.? I don't know 
which flavor of mic those two are, but page 28 of the K3 manual (and 
nowhere else I can find) explains what to do.

Subject: [Elecraft] K3 - HI RFI alarm
Message-ID: <CALxojYLDiFsfV1DT5r92d06U_Ja=Xiz2FwSzCOweSj73y9CSKg@mail.gmail.com>

I've had my K3 since around 2007 and recently have started getting a HI RFI
message on the LCD while operating CW and using my AL-811 amplifier at
about 500 W.

It seems odd since when I'm "key down" my antenna should not be connected
to the receiver.

I'm not using QSK. I have a bit of delay to keep the amplifier's T/R relay
from operating between characters.

I don't have a separate antenna connected.

I've run 100 W or QRP most of my ham life but for the past five or more
years I've occasionally used the AL-811 and had no issues until recently.

My antennas are a 134' EFHW inverted L and an 88' dipole fed with ladder
line via a Johnson Matchbox.

CW SS is coming up.  I'd like to use the amp but worrying about my receiver
may be distracting.

Anyone seen this?

In late July Madelyn's estimate puts delivery in late November/early December. I don't know where October 1 came from. here's her July 28th message again:

"We are still hopeful we'll be able to offer the sub rx but I have no ETA for that at this time.

The rest of the options can not be ordered because we'll have final numbers tallied in the next couple of days - that's why the orders were
shut down.  The vendor is telling us 10-12 weeks (appx) from the date we order boards + another 2-3 weeks testing, bagging, tagging, etc once the
boards arrive here."

Never seen a HI RFI indication before ... could it have been HI RFL [hi

By far it is the most fun per watt of any radio that I have ever owned.

I worked HD8R on 15 with 10 watts to a random wire.

While I own both the KX2 and KX3, when I was trying to work HD8R on 40m
with an Inverted V in the early evening here in SoCal on FT8, there was a
HUUUUGE pileup.  In my case, the K3 (upgraded to K3S) with the KPA1500 was
the trick.  It took me an hour and a KW, but I finally got through.   So I
guess the story here is that, depending your circumstances, Elecraft has
the tools to get the job done :)

Perhaps you could clarify what you meant by a modern OCF. What?s changed from the traditional model? Thanks.

I own an upgraded K3, a K3S, a KPOD, a KPA500 and a KAT500.? I used the latter 
two with a brand K transceiver and very modest antennas to work them (so far) on 
25 of the 29 slots they operated on.

In my book six-meters doesn't count and they only made a handful of 60-meter CW 
and SSB Qs so that doesn't either.? They operated briefly on 20-meter RTTY while 
I wasn't home :-(

My only nod to QRP is that the whole station runs on one 20A 120VAC circuit.

My story is too good to pass up this bragfest.  On October 7 I had a
serious lightning strike.  It damaged five pieces of elecraft gear, K3s,
KX3, KPA500, KAT500, and P3.  All have been sent to Elecraft for repair and
I must say the response from them has been excellent.  I was left with two
radios, a homebrew tube Tx (10w) for 40 meters and a Drake 2B, plus my
venerable K2/10W, built in 2004.

On October 14 I had previously scheduled a 200 foot crane to install three
new JK antennas to replace all of the antennas on my 155 foot rotating
tower, which had been destroyed by a winter ice storm.  On the 14th, the
crane showed up and also 8 of my DXer friends to be ground crew.  All went
well and I now have a 2 stack on 40 and a 3 stack on 20-10.  There is only
one more problem.  The rotator motor was killed by the same lightning
strike.  The tower is bolted in a fixed position, pointing to S. America.
If anything shows from that direction, I work it.  It is a killer antenna
system and I live on the highest point in the county.  It's been a great
location for me for the past 32 years.

So HD8R appeared on the lower end of 40CW a couple of nights ago, pounding
in, because the antenna was "only" 25 degrees off line.  So I called and
worked them with 10 watts out of the huge pileup with the K2.  It took 30
minutes.

Getting back to the antenna party, one of my "buddies" took it upon himself
to escort each of the ground crew, one at a time (COVID) into the hamshack
to see the carnage, which included a three fingered sized hole in the back
of the KPA500 where the line cord module used to live.  As they came
through the door, I overheard him say, "please sign the guest book."  In a
way, I guess it was similar to the viewing of the deceased at a funeral.

A call from support has assured me that the KPA500 will live again with the
organ transplant of three modules and a few bucks.

BTW, it was the easiest I have ever put up an antenna in my 64 years.  I
just sat under a canopy and watched as I am almost 80 and gave up climbing
three months ago.

We ARE having fun, aren't we?

73,

Dave, K4TO

Hi Dan

Good question.  I'll answer as a non-expert as best I can. 

This is essentially a quest for a multi-band dipole that is easy to make and use.  If you can put up mono band dipoles and beams for all your bands, you probably will not bother going this route. 

The popular description of the ocf dipole (going back at least to the 50's) has a feed point of one third/two thirds on the dipole.  (BTW this is otherwise a normal half wavelength dipole.

This provides approximately 200 ohm feed point impedance for most popular HF bands, eg 80, 40, 20 and 10m, not 15m.  

Back in the 60's we could use coax into a valve PA, which I preferred to the G5RV which needed an outboard matching unit.  In transistor days we used a modest matching unit with an swr meter and were ignorant of common mode current.  
 
In the 90s I used ladder line to ground level and an auto-tuning unit into a tent for field day, believing it to be more efficient.   With grounded coax I didn't have live chassis syndrome and out in the wilds there was no noise pickup.  Later I used ladder line through a balun then into the radio with an on-board matching unit and that was, for me a great step forward with auto-tuning.  


It was discovered by some users that the common mode current performance using off-the-shelf baluns and chokes was inadequate and could result in live chassis syndrome and noise pickup on receive from home locations.  Poor matching on 15m was still a problem as were the WARC bands. 

Now in the 21st Century, just a few years ago, Rick DJ0IP tackled the problem starting with a 40m ocf dipole using a new balun/choke combination.  He read that W8JI and others recommended a 20% feedpoint to bring 15m into the 200 ohm region. He then used a Guanella 2-core balun solution from Steve G3TXQ and others to provide the 50 ohm output with low common mode current.  It had to be the dual core version, the single core version simply didn't suppress the cmc.  This is now marketed by Spiderbeam.  Moving to an 80m version was difficult but with a hybrid balun/choke combination he devised a combination that provided at least as good cmc and this version is also marketed by Spiderbeam. They both work on 15m and some WARC bands. For some layouts a modest on-board matching unit is required for complete coverage which is a far cry from bulky outboard units; good news for portable operation.  

I would call these *modern* off centre-fed dipoles, ie well into this century.  

I have no financial connection with anyone in that business and I will say that I have never seen anyone else produce such a large amount of compelling evidence as Rick and I recommend his web site for all things balun and choke related to this task.  He takes the practical, non-laboratory approach.  This in no way conflicts with any work done by Jim, K9YC and I only wish that he would make his own measurements on these modern devices and let go the old prejudice.

NOT SO, DICK TRACY !

While YOUR OCF dipole may have problems if poorly deployed and implemented.  It is a PLAIN FACT based on thousands of real world examples, OCF Dipoles DO WORK WELL.  Mine works very well with NO CMC or other problems.  A few years ago, I gave some minor assistance to a notorious German operator, DJ0IP, as he collected a wealth of empirical data on CMC and OCF dipoles, carefully testing multiple examples before designing a commercial product that has been well received by the QRP crowd, receiving positive reviews in the RSGB and ARRL magazines.  He received even more assistance from W8JI and G4TXQ and others,focusing their attention on how to avoid common mode current (CMC),  discussing where to offset the feed point, and how to construct a proper combination balun and choke.  My OCF Dipole is split 25% /75% split and Rick selected a very different feed point, and all is good.

CMC is NOT a necessary evil as Mr. Brown suggests. It CAN be curtailed with "proper care and feeding" (pun intended) and the proof flies over my shack, and over hundreds of other shacks, including DJ0IP's station, around the globe.

Pedantic dogma be hanged !!  I base my claim on 1) real world results,   2) TONS of empirical research by others,  and 3) input from my local Elmer/guru who designed RF gear for NASA and the AIR FORCE and commercial interests.  Mr. B's theory is out of step with the real world.    (smiling as he typed that, Pardner...)  :-)  -K8JHR-

Sorry about the October 1st mention - I thought I had
placed my order for the KPA3A 100 watt upgrade
module at the end of June 2021, but it was the
end of July.  I estimated 12 weeks from end of June,
and that is the source of the mistaken October 1st
date (the "shipping no earlier than" date).

I wrote to Elecraft and received a nice response
from Madelyn Gomez, which I won't reproduce
verbatim here.  I was told that long lead time
components are the source of extended delays
in filling orders for the K3/K3s "last call."  It
may be 4-6 months before those boards/modules
are received in-house at Elecraft.  I was told
that product-specific estimated availability dates
will be posted within the next several weeks.

Sorry for creating any false panic - looks like
we have plenty of time to work on other
projects before some of those upgrades arrive!

Message-ID: <6E66E30D-B230-46CB-8342-FC15CA325328@arrl.net>

About 10 days ago, I was having trouble with the K2/100, as it was no longer talking to WSJT-X correctly. I could get the audio running, but it would never contact the radio.

Trying to set up for CQ WW Phone, I had the same trouble with N1MM.

Tried to use the PORT TEST feature by going to the SEC menu, selecting PORT, going into EDIT, and pressing the DISPLAY button. It would say TEST, but I?d see no characters transmitted. 

Since I use USB serial adapters, I tried two of them, to no avail. Can?t get a peep out of the K2/100.

Opening up the rig and digging out the scope, if I send characters on the serial port, I see pulse trains on KPA100 U4 - the MAX1406 chip - pin 11 (R3OUT). So, it would appear that characters are reaching the main CPU.

If I put the scope probe on pin 12 (T2IN), it remains locked on ground, never moving, even when I do the PORT TEST. 

If I remove the P1 connector from the control board, and put the scope probe on pin 1 of that connector, I DO see pulse trains from the PORT TEST. This indicates to me that the CPU is OK, but something is wrong at the MAX1406 chip in the KPA100. 

In addition to not getting a response from the K2, it doesn?t appear to obey commands. If I send RT1; or XT1; it doesn?t turn RIT or XIT on.

I tried using a different main CPU chip (I have one with older firmware), but that doesn?t appear to make a difference. I?m wondering if my problem is a blown MAX1406 chip.

Any recommendations or advice? It?s a big pain to remove the KPA100 board, so I want to make sure what I?m replacing before I go after it.

Not Dick Tracy here, nor am I K9YC.

I had very good results running mobile with 100 watts and a hustler on the
roof of my Suburban. I also have fun with my kx2 and a random wire 15 feet
high out the window to a tree.

Your notes about the success of various real-world examples leaves out what
the comparison would be with a true dipole. For a true test, you would need
to do a head-to-head comparison of the two antennas. K3LR used to do this
at Dayton.  Proof is not how many OCF antennas fly above roofs, but how do
they compare to a similarly situated dipole.

A true test of equipment and antennas is how well they do in a contest.
With these OCF antennas, can you work 100 countries in a weekend on
multiple bands? Can you get to 300 countries in DXCC? Much less likely than
dipoles, properly built verticals or beams.

Can you have fun with OCF or other compromise antennas? Yes. But other
antennas are likely to do better.

Bill,

Make certain you have +12 volts on U4 pin 1 and +5 volts on U4 pin 16 
and about -25 volts (-8 to -27 volts) on U4 pin 8.
If those are correct, replace U4 and it should work)

Exactly right. On my Chicago city lot, I had a fan dipole for 20/15/10, 
a trap dipole for those bands, and an inductively loaded dipole for 80 
and 40 that also worked in some directions on 30, and that I used as 
top-loaded vertical on 80 and 160M, using a wrought iron fence as a 
counterpoise.

I wonder if this food fight might reach its denouement on another channel?

It seems to have been sparked by an OCFD discussion not relevant to anything Elecraft, and to have evolved into personal preferences and grievances. 

Maybe we should take on End Fed Zepps next?  Or take the whole thing off-line?

If it continues, we are indeed eminently qualified in the use of our delete buttons.

Hi David,

Thanks for the synopsis below.? I found it very useful being unfamiliar 
with amateur practice over the years with OCF antennas.? My antennas are 
all center fed.

I replied to this message because it was the most informative. Other, 
later messages on this thread were also interesting.? But generally, the 
discussion lacks quantitative data and so it is difficult to objectively 
evaluate the efficacy and drawbacks of different realizations.? It is 
also difficult to project which realization or changes would fit a given 
set of constraints.

The positive aspect is there has been years and years of experimentation 
and different approaches to this multiband dipole problem.? I would like 
to hear more on these.

Could you describe G3TXQ's 2 core Guanella balun solution more 
completely?? I checked the Spiderbeam website and it is not clear to me.

I think this is relevant to Elecraft since many applications are 
portable and QRP.? We want that antenna to really work and understanding 
it better, helps.

73,

Chuck K0MV

Subject: [Elecraft] PLL Range test
Message-ID: <F35945FC-4255-4BAD-B465-B4813C475B86@comcast.net>

Hello again,
Still building a K2. I got to the PLL reference oscillator range test and did have to remove one turn from the toroid.My range at first was 20.6 Khz.
I got it down to 15.38Khz. I am worried if I remove another turn it will be too low. I went ahead with the continued testing and all the numbers (test results) are good.
I stopped for the night on the BFO alignment.
My questions is, is the 15.38Khz ok or do I need to remove another turn from the toroid?

Comparison with a real dipole...

--------------------------------------------------

My local expert (and the ARRL Handbooks) and others, including I believe 
Joel Hallas of the ARRL,? all say an OCF Dipole? IS A DIPOLE and 
radiates just like a center fed dipole, but with a different feed point 
impedance ,? which is resolved with a matching unit (choke and balun. ) 
 ?? Where is your proof the OCF radiates differently??? If different, it 
won't matter enough to make it a poor choice.?? Nonsense.?? K8JHR

Chuck

I'm not an expert but you might find it useful to read
http://www.karinya.net/g3txq/baluns/baluns.pdf

Antennas popular with Elecraft back-packers are off centre fed dipoles: eg 20ft of wire up a tree and 10ft of wire on the ground as an example.
Many low power and one-man dxpeditions use these antennas and win trophies!  
I used an 80m ocf dipole in an IOTA contest with team CR5CW running 100W and a K3 and did pretty well. 

As has been said on many occasions, there is no real difference between a dipole fed in the middle and one fed off centre: as long as you can get the current to run in the dipole by suitable matching and don't waste it along the way, they are indistinguishable to the dx station.  Centre fed multi-band antennas can waste power in the matching unit, take care. Use Elecraft internal matching and it's all plug and play. 

Build one or buy one and just have multi-band fun from one antenna.

To follow up on my question about the PLL range test, how critical is it to be at or below 15Khz? Currently I am at 15.40Khz after playing around with the winding spread. The errata sheet says to be between 9.98Khz and 15Khz difference in the high and low reading.

GM James,

I think you will be fine with a 15.4KHz range. The problem when approaching ranges much greater than that is that although the K2 firmware will linearize the VFO adequately, the granularity of fine increments may start to suffer, and it'll be more susceptible to temperature change.

If you like to experiment and have enough #26 red enamel wire left, you might try taking off another turn and see what the range is. If not, then I think you will be just fine with your range.

BTW - I did all the testing for this change and used a set of cores to perform multiple tests. I saw these variances as well from the same batch of cores. The mix varies some between cores and produces different inductances with the 15 turns of #26 wire. Some I had to take a turn off and some were fine. I had one that produces a 18KHz range. Pulling a turn returned it to around 15KHz.

73,
Dave, W8FGU

Subject: [Elecraft] K4 or K4D
Message-ID: <44a38e33-e9b3-b7a3-c793-3abcca70246a@comcast.net>

I operate from a 50 by 115 foot lot using a tribander and two open wire 
fed dipoles.? I use a K3 with the auto antenna tuner, but no 
panadapter.? Primary interest is contesting (usually qrp and S&P) and DX 
chasing.? I never operate 2R in contests. There can be fairly high rf 
noise levels in the neighborhood, say S3 to S6, but not always.

My question is this:? Does the K4D have a real advantage over the base 
K4 for me.

Thanks for your opinions.

The reasons to get a K4D over a K4 I think are only:
1) You need diversity receive.
2) You need to receive on two frequencies on different bands while still
having bandpass filters engaged (the K4 can receive on 2 separate bands at
once, but it has to bypass bandpass filters).

Chuck

I'm not an expert but you might find it useful to read
http://www.karinya.net/g3txq/baluns/baluns.pdf

Antennas popular with Elecraft back-packers are off centre fed dipoles: eg 20ft of wire up a tree and 10ft of wire on the ground as an example.
Many low power and one-man dxpeditions use these antennas and win trophies!  
I used an 80m ocf dipole in an IOTA contest with team CR5CW running 100W and a K3 and did pretty well. 

As has been said on many occasions, there is no real difference between a dipole fed in the middle and one fed off centre: as long as you can get the current to run in the dipole by suitable matching and don't waste it along the way, they are indistinguishable to the dx station.  Centre fed multi-band antennas can waste power in the matching unit, take care. Use Elecraft internal matching and it's all plug and play. 

Build one or buy one and just have multi-band fun from one antenna.

He read that W8JI and others recommended a 20% feedpoint to bring 15m into the 200 ohm region. He then used a Guanella 2-core balun solution from Steve G3TXQ and others to provide the 50 ohm output with low common mode current.  It had to be the dual core version, the single core version simply didn't suppress the cmc.  This is now marketed by Spiderbeam.  Moving to an 80m version was difficult but with a hybrid balun/choke combination he devised a combination that provided at least as good cmc and this version is also marketed by Spiderbeam. They both work on 15m and some WARC bands. For some layouts a modest on-board matching unit is required for complete coverage which is a far cry from bulky outboard units; good news for portable operation.

This in no way conflicts with any work done by Jim, K9YC and I only wish that he would make his own measurements on these modern devices and let go the old prejudice.

Statements like this ignore three fundamental facts.

1) Off-center fed antennas are noisy on receive, and you can't work who 
you can't hear. This usually doesn't matter in the middle of nowhere, 
but it matters a LOT in most of the developed world, where all of us are 
surrounded by switch-mode power supplies (almost everything that plugs 
into the wall), controllers for variable speed motors (HVAC systems and 
other systems), grow lights, and solar systems.

2) When used on bands other than their half-wave length, horizontal 
patterns are wildly variable, with multiple peaks and nulls at angles 
predictable by antenna fundamentals.

3) It is impractical to EFFECTIVELY choke them at the feedpoint to kill 
RX noise, the feedpoint being at the off-center point on the horizontal 
wire, not down the matching section from the antenna, and it is also 
impractical to EFFECTIVELY choke a feedline where it is severely 
mismatched. Again, this doesn't matter in the middle of nowhere, but it 
matters a LOT where most of us live.

And it DOES matter to the DX station who calls you repeatedly and you 
don't hear him, thanks to your RX noise. This has been happening to me a 
lot on 60M FT8, where I'm licensed for 100W EIRP, and most of the rest 
of the world is licensed for 15-25W. That power gives me a 6-8 dB 
advantage, and stations I decode at -10 dB don't hear me!

James,

Listen to Dave, he is 'on target' with his post, and he is now the K2 
'expert'.? But it might be helpful if you post the PLL high and low 
frequencies as well as the range test results.

I have assigned the K3S' sound card.? I am in DATA AFSK mode, 45-45 baud,? 915 (I like it low) 170hz shift.? I appear to be receiving (though who knows, no rtty signals).? Port # is correct.
Help a Noob.? Bonus points for how I set rx text to something larger than 2pt--you know, human-readable.
Thanks!

Message-ID: <CAOoYq89rg-geW6t9G7OEXbTJ6HK3fu6Pk5TfCv5hb4c09DgT8Q@mail.gmail.com>

Some background here -

I volunteer aboard the museum ship USS Slater in Albany.  She is a
destroyer escort restored to her 1945 configuration as she was sent from
the Atlantic to the Pacific after VE day.

I try to put it on the air every time I'm there, once a week or so,
maintenance issues allowing.  We use a K2/100 and KAT100 patched through a
WW2 vintage Transmitter Transfer Panel to a choice of the ships original
wire antennas.  These were mostly verticals used for receiving back in the
day.  We can also use the two original transmitting antennas, long wires
running fore and aft.

We are restoring a TBL 400 watt transmitter, which is only connected to the
fore and aft long wires.  The output exits the top of the TBL cabinet and
consists of copper tubing that runs along the ceiling (I know, overhead...
I'm a civilian) to where it exits Radio Central.

Legend has it (and I have no reason to doubt it, I've seen the repair
invoice) that the last time the TBL was fired up the KAT100 was damaged.
Our practice is to unplug the feedlines to the KAT100 at the Antenna
Transfer Panel, as well as where they connect to the rear of the KAT100
itself.

The repair invoice says ?The wattmeter in this KAT100 had been damaged. D1
and D2 were replaced. R1 was found to be open and replaced. C31 was not
well soldered. ?

Im wondering if unplugging both antenna feed lines from the KAT100 is
enough protection from a 400 watt transmitter firing up a few feet away?

K3 calibration and configuration is also available.

Does your K1 or K2 need repair? Tuneup?
Want to sell, but it needs some attention before offering it for sale?
In addition to tuning your rig, I can also rescue a building project you 
might have started some time ago.

My situation is similar to Dave's.
I live on a suburban lot 70' x 140' but only have dipoles at the 
moment.? I purchased a K4F (base K4) and have no regrets.? Although I 
still have my FT-1000D and may try for SO2R at some point in the future, 
the base K4 is perfectly adequate.

One never knows, Chuck, RF can be very unpredictable.? If the TBL were 
feeding coax, you'd probably be OK just disconnecting the K2/KAT 
antenna.? Given that part of the TX antenna is inside the shack a few ft 
away and shipboard HF antennas are rarely resonant, I would plug a 
shorted PL259 into all the Elecraft ant connectors.

Good Evening,

 ?? We are in the rainy season, there is no doubt about that.? A few 
minutes of snow, even with the snow level at 5000 feet. Perfect weather 
for a large expanse of mushrooms.? The birds have fluffed everything up 
for the detrivores.? The mycelial mats now have a great substrate for 
fruiting bodies.? Next year the current crop of ferns will become soil, 
you can smell the forest is still very active.

 ?? Due to the CW portion of Sweepstakes I will take tomorrow off from 
net duties.? The week after I will be back at the PST times. I will keep 
checking forty meters through the week to see where the "knee" in the 
propagation occurs.? It is best to avoid that time because ops can 
vanish in seconds.? We will adapt.

 ?? Stay warm and 73,

 ????? Kevin.? KD5ONS

Message-ID: <emc6400ecc-5580-4a92-afdc-0bd71a6a7e67@jimsdesktop-pc>

My K3S died a couple of weeks ago and I haven't found the power supply 
problem yet - difficult tracing as I don't have the board trace layout 
so finding components off the schematic isn't easy, LOL.

On a lighter not, I replaced it as the shack rig with my KX2 and I've 
been having a blast trying (and sometimes succeeding) to work the 
Galapagos DXpedition HD8R.

With the ARRL Sweepstakes contest on this weekend, HD8R has been 
concentrating on the WARC bands and so far I've worked them on 20, 15 
and 12 meters (12 just a few minutes ago, using my Tri-Band Cushcraft 
A3S  beam as the antenna.  Got 'em on the 2nd call much to my surprise.  
The KX2's internal ATU had no problem matching the beam on 24.894 
(1.0:1) and signals have been pretty decent on 12.

Ant loads on 17 meters too but signals are up and down on 18.074.  Fun 
to keep trying though and the KX2 is running great at 10 watts on a 5 AH 
battery.

Worked them the other day with my Kx2 but to a random wire.  Did it while
on the job--called for several hours, But very satisfying.

Plus it seems that they have very good operation.

The Sunday Elecraft SSB Nets begin with the 20 Meter Net at 1800 UTC on or about 14.3035 MHz with Eric WB9JNZ as Net Control in Chicago. The 40 Meter SSB net follows at 1900 UTC with Steve WM6P in Georgia serving as net control on 7.280 MHz.  At 0100 UTC the 80 Meter SSB Net meets on 3.775 MHz with Net Control Paul KB9AVO from Indiana.  We employ several relay stations located around the continental USA to assist with check ins.  As conditions permit we take questions and comments after check ins.

Give one or all of the SSB nets a try next Sunday.

Having just trawled through the HTML file to create a stylesheet to
override the colors, there are at least twenty-five different
elements/classes with color choices. Some are redundant, and some span more
than one purpose. I'm also not sure what system they are using to edit the

That said, I did manage a relatively readable black-on-white HTML version.
If you'd like the stylesheet and instructions on applying it, please let me

Looks like tonight's 80 meter net is a bust.

The time change moved it to 8pm ET, but the folks that occupy 3775  
just before our net apparently are on local time, instead of UTC, so  
there wasn't a clear frequency there or 10 kHz either side.

I did try calling a few times on adjacent frequencies, but got no callers.

Looks like if this keeps up, we'll need to find another frequency  
(again), or maybe move the time?

At 855pm ET, the frequency is now clear.  I'll listen for a bit after  
9pm to see if it stays that way.

I'll give a couple of calls, if you want to check out the path at this time.

Dave, You were just above the noise level and a guy on 3778 was splattering all over you. I think the guys that were on 3775 moved up there.
Oh, well.

Message-ID: <527181140.225060.1636388757473@connect.xfinity.com>

Good morning everyone.
I have finished the basic CW version and all my checks and alignments are good.
The question I do have is, the capacitors (101) tan in color, have the legs bend in a zigzag pattern. When I tried to straighten them I ended up cracking the ceramic insulation on them. So I replaced them and installed all of them without straightening the legs. That of course put them a bit tall on the board. The manual states to install all components as close to the board as possible, to avoid stray RF coupling on the board. 
Do you all think the way I installed them is going to be an issue? And how would I be able to tell if it is a issue?

Thank you for all the help I have received so far from this group.

I think you just have to read the instruction manual for installing it and work backwards.

Don't straighten them!
Back about a hundred years ago when I built my K2 #725, I caused an 
invisible open circuit failure in one of those capacitors as a result of 
straightening the leads. It wasn't easy to find. Don't do what I did.

Many instructions for options, such as filters, include directions on how to temporarily remove the second RX. To permanently revive it, you would need the instructions for the second RX installation and reverse it. You would need to find all the odds and ends including the back plate to completely reverse it.

James,

It is not? likely to be a problem, but check any that are on the 
bottom.? If they are too high to clear the bottom cover, just bend? them 
over a bit.? Replace the ones with the cracked bodies.

Worked them the other day with my Kx2 but to a random wire.  Did it while

Check out when the first contact is 26/10/2021   They are using the European date style (day / month / year).  With that in mind, the last contact in the log is 8-Nov-2021.  I did a double take on the dates, before I figured out what they were doing.

I'm in the log for a contact yesterday (ATNO) - but not my contact during the CQ WW SSB contest.

Have an older K3 that is now out of balance with audio  on the headphone line. Right side is now low compared to the left. 

It was at the factory just over a year ago. 

Is there an adjustment for this?

Hi,Regarding th use of external Transverters with KX3, the functions "XVn RF" and "XVn OFS" have to be used.The XVn RF can only be set to a full MHz, and the XVn OFS can be set ?9.99 kHz.If You have a transverter with a slightly bad crystal, that will not oscillate on the intended frequency, You have to use these two functions.Suppose the offset is +55 kHz, which is a relative small offset on 47 GHz;? +0,00012 %...
How to set up the KX3 to include this figure, so the frequency readout is the actual frequency You want to operate upon in the 47 GHz band?This will not work, unless:"XVn RF" can be set to steps in 0.1 MHzand"XVn OFS" can be set to ? 50.0 kHz.??This will give You the chance of letting the frequency display be within 100Hz of the actual output, regardless of the wanted offset.?I guess this is a subject for a F/W modification.?Best regardsBjoern?

I normally use a K3s in a highly competitive 6A field day environment.  One year my K3s had a problem and a KX3 was substituted.  I did not notice any problems in the multi transmitter environment with the use of the KX3.

I don't have a KX3, but a friend does and he has a question regarding the KX3 receiver in a multi transmitter environment like Field Day.  I would not expect it to be as good as a K3, but is it usable?  Anything special you have to do to it?  I'm thinking at a minimum a set of band filters, which would be easy even with the 100 watt amp.

Thanks for your thoughts and experiences.

Keep in mind that if you use the XVn OFS feature on a KX3 (latest 
firmware) and your offset is bigger than 0.66, you trigger a firmware 
bug where the firmware will crash and squeak if power-off and power-on 
the KX3.

Unfortunately, the KX3 is not so nice with transverters; there is a 
longer list: https://github.com/drewarnett/kx3-firmware-issues/issues/
(sent multiple times to support, Eric and Wayne directly; no response, 
and most of the issues should be less than 30 minutes work for someone 
with access to source code, and can be done in full Corona-isolation)

In my case, my transverter-setup is GPS-locked and I don't need the OFS 
feature. But software maintenance to older models doesn't reflect well 
to Elecraft's newest offerings. And that hurts. A lot.

What digital modes?  For WSJT modes, study their documentation.

For all digital modes, use Digital A, feed audio from computer to Line 
Input (Mic Gain becomes Line In Gain). Adjust audio levels so that CMP 
shows 4 bars flashing 5 when transmitting. Don't bother with using 
control lines for PTT, use VOX, set VOX gain so that rig keys reliably. 
To decode the weakest signals, set audio gain from rig to computer so 
that when receiving, green bar at left side of WSJT-X is as high as 
possible without turning Red.

Don't tell WSJT-X to configure your operating mode, do that manually. 
Set Split to Fake It. All you need rig control to do is set and read TX 
frequency.

Make sure that all the equipment in your station, including the 
computer, is properly bonded -- chassis-to-chassis, and to all the 
grounds in your home (rods, coax entry, power, telco, CATV), that all 
end-fed antennas have an effective counterpoise, and that there are 
effective common mode chokes at the feedpoint of all antennas. All of 
this is good engineering practice for all modes, most of it is required 
by law, is critical for lightning protection, and minimizes RF feedback 
(RF in the shack) that can interfere with good operation.

For proper bonding, study N0AX's ARRL book on the topic, to which I 
contributed, and/or the pdf of slides for talks I've done at Pacificon, 
Visalia, and to several ham clubs.

Can't help with configuring those other programs.

Brian,
Everything Jim said, plus a couple additional recommendations:
1- I would start by using WSJT-x by itself for a little while, configured
to talk directly to the K3, without DXLab Commander or Win4K3 running. This
will allow you to get familiar with WSJT-x, its configuration, making
contacts, etc. without anything else getting in the way. Make sure the
computer?s time is accurate using a time synchronization utility like
Meinberg or similar. The built in logging in WSJT-x will create a ADIF file
that you can import to DXKeeper later, so don?t worry about manual logging.

2- once you?re comfortable with the above, read
https://www.dxlabsuite.com/dxlabwiki/GettingStartedwithK1JTModes
and follow the instructions. If you already have Commander talking to your
K3 through Win4K3, just keep that configured as usual. WSJT-x can be
configured to use DXLab Commander as it?s ?radio? per the instructions in
that link above, so nothing needs to change for rig control if Commander
and Win4K3 are already working for you.

I've been quite happy letting wsjt-x operate in split mode with 
my K3. The only downside I've found is having to manually turn 
split off to make some changes when operating in other modes. I 
hope Jim wil explain his recommendation.

If you're just going to use WSJT-X (or JTDX, which is what I use) for
non-contest / casual operation on the main FT8 frequencies, I don't think
using the split/fake-it option is necessary.  Contesting is a different
thing.  To get started with casual use, just use the TX/RX split option on
the main UI.  I've also had mixed results using JDTX with a serial pairing
emulator (I use Eterlogic, but have tried several) and Win4K3.  It mostly
works fine, but I have noticed that over time the TX/RX timing sequence
starts to become "off"...I've only done light troubleshooting on this so
far, but I know it's not a CPU horsepower problem.  So when I'm doing JTDX,
I usually just use the HRDLogbook host and leave Win4K3 shut down.

My 2C.

Brian:

I suggest you get WSJT-X working as a stand-a-lone application before 
getting the other applications running.? This will allow you to get the 
audio levels for RX and TX configured.? And will allow you to use CAT 
control for the radio and PTT mode.

DX Labs and Win4K3 can come on board later.? It is much easier to debug 
software system integration one step at a time.

I got HD8R with 100 watts CW to endfed wire antenna. Here's a short

I had a discussion about this sort of madness with Joe Taylor, creator of FT8 and WSJT-X. Here's what he had to say about it:

"Hi Richard,

"Yes, it's annoying when people engage in a QRO arms race to make more QSOs or make them more quickly with FT8. Using high power is one thing when conditions demand it, as with some 160 m DX paths, for example. It's quite another thing when high power is not required to make the QSO, but only to help you get through first.

"However, it has always been thus, and there's not much anyone can do about it. As a general rule it's often useful to move up above 2500 Hz or so, audio frequency. Or even to set your dial frequency 1 kHz higher than the default for a band.

"We are also thinking about suggesting a "QRP FT8 sub-band" in which power should be limited to 10 W (say).

I must be missing something. FTn isn't like CW or SSB where the loudest
station often wins in a pileup. If you have enough FTn signal to be decoded
reliably, say -10 or better, how does more power enhance your chances of
getting through? WSJT-X chooses whom to answer based on a "first decoded"
algorithm that I don't fully understand but it doesn't seem to be based on
signal strength. I often get multiple callers and the loudest one often
isn't selected. I'm surprised Joe didn't point that out - it's his mode,
after all. But maybe there's something I don't understand.

FTn are modes in which the standard FCC guidance to use the "minimum power
required" seems to make sense. I set power based on incoming signal
strengths. With my antennas, 40W usually gets through to anyone -15 or
better, often to -20. If most signals are weaker or if a station "calls CQ
in my face," I QSY to another tone that might be clear on its end and/or go
up to 80W. I turned on the amp at 200W one time when I was decoding a new
one only sporadically and expected I would also be weak. Got it. ;-)

Hi Rick,

FT8 and similar modes are weak signal modes, and for difficult paths, 
it's all about signal to noise, not signal to QRM. For several seasons, 
I've been running legal limit to fill in DXCC to eastern EU on 160M. 
During the summer, many of us run legal limit and lots of aluminum on 6M 
for weak and brief multi-hop Es openings to fill in missing grids in 
search of the Fred Fish award. We also run power for meteor scatter, and 
most who do moonbounce run legal limit.

The fundamental GOOD reason for power is RX noise on the other end of 
the QSO. I regularly give signal reports 10-15 dB better than I receive, 
simply because most hams are bathed in electronic noise from their own 
homes and those of their neighbors. Noise levels have increased 
drastically over the years. When I first moved to W6 in 2006, I could 
work EU on CW. Not a lot, but at least 3-4 QSOs per year, sometimes 
more. In the last six years, I've HEARD 6 CW signals from EU, and only 
two heard me. And my 160M antenna farm is better today than it was then.

I have both K3 and KX3 and used both radios for contesting.

KX3 has much lower BDR and unusable when there is another local or 
strong inband transmitter. It also switches preamp off and ATT on 
automatically when the radio hears inband signal of 59+30db or more. 
Another shortcoming of KX3 is that the RX image channel is only 
suppressed by 50-60 DB. Conclusion:

K3 is sure much better radio for crowded contest then KX3.

I would not expect it to be as good as a K3, but is it usable?  Anything special you have to do to it?  I'm thinking at a minimum a set of band filters, which would be easy even with the 100 watt amp.

Message-ID: <CADnt6w3SqqKUYMX7=CLv21YRCN7pqKt3SOX42tpq3ugeMyg=3A@mail.gmail.com>

This is my 2nd K2 build this year. This fantastic kit has kept me sane.   I
tested every component on an LCR meter (found RFC10 open) and tried to work
as slowly as possible.

I got to the end of the build to the very last alignment step.--

The adjustment of C44 and C46 for the 12 meter band and I can only get
0.2W. 10 meters is fine with adjusting L12 and L13 but 12 meters (which I
do not use but it should work) is nada.

I had the exact same problem on 20meters but careful tweaking of C21/23 and
L8/9 and it burst into life.

When testing the capacitors I noticed they had quite a wide tolerance
range. Could the band pass range for the 10 and 12 meter bands be too high?

Any ideas would be appreciated. I am quite good at wondering down rabbit
holes.

There's a major jerk who lives within about 20 miles of me who runs BIG power with FT8. When he's on the air, he blots out my K3S so his is the only signal on the waterfall, the only signal the decoder sees. When his BIG POWER is on the air, I can't be. And he's made it clear that he doesn't care what he does to anyone else's enjoyment. Power for power's sake is contagious.

On the other hand, I've made several 10,000 to 11,000 mile Australian contacts with 15 watts and a hex beam at 30 feet.

Richard -

As of today, I have worked 40 stations in VK6-land ... the farthest land
mass area, for me, on Earth.

This is with 50 watts (or less) FT8, mostly on 40 meters, mostly 0800 - 1300
UTC and, basically, an oversized dipole at about 35 feet (actually a 3.5 MHz
EDZ - but that's another story).

Included in that bunch is THE station that appears to be the furthest from
me located on land (a MM in the South Indian Ocean might be farther, maybe).

I gave him a -15, and he gave me a -07.  QRZ distance, 11,026 miles.

I use whatever power is required to make the intended QSO.   It really bugs me when people brag about their prowess with QRP operations when they don't declare the antenna that was in use.  Power output means nothing unless it is qualified by antenna gain.

Often a good idea of the required power can be learned from a single TX and a review of PSKReporter.

Just worked Reunion Island from Arizona with a home brew magnetic loop on 30 m.  99 watts resulted in a -17 report so I could have used less power.  I'm not going to get too stressed about it.  Instead I'll marvel that my inexpensive home brew mag loop can reach half way round the world.

73,
Andy, k3wyc

Drew:

Cool collection of keys!

Congrats.

I was quite lucky to work them with my KX2 and a random wire out the window
from my office during work hours. (Big Iron, rather Silicon is in the
basement shack.)  I would hit the MSG then PRE to send my call. After
several hours of trying I was able to snag them. This was on 15 meters.

And from what I can tell, they had a super operation. Good ops, and they
appeared to hear quite well.

I suggest that the problem is not his power. Instead he is almost for sure
overdriving his audio input.

Since you are off on the wrong foot with him, maybe you can get some other
local to approach him in a helpful way.

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.

73,
Rick NK7I

When that happens to me, I just ensure that I TX at the same time as the 
STRONG signal, at the oppsite end of the audio passband, it usually 
works good and allows me to make contacts.

Thanks, Bill.

Sometimes I use the CW msg memories on my K3 but find it is more fun 
with a manual key. I guess it is less monotonous than pushing the msg 
button over and over.

Here are a couple other DX vids featuring the venerable K3:

One very effective solution is to configure WSJT-X to receive when he is 
receiving and transmit when he is transmitting.? Thus you would never 
know he exists.

I agree, abuse of power is not a good thing.? It is more a case where 
hams have more money than good operating skills.

Hi, James -

Sometimes, pictures and narrative can help the build process.  I built my
K2 a number of years ago, and
pretty extensively documented the build.  I hope you find this helpful:

Marc,

Please check the placement of those trimmer caps. If you follow the old 
parts list, it is easy to swap C21 and C23 with C44 and C46. If this is 
a recent kit, C44 and C46 should be red. While the others will be brown.

I just serviced one here that had the same issue and those trimmer caps 
were swapped.

Although very little information was provided, I've observed when this 
occurs, it is usually due to something that caused a flash-over in my 
amp or my tuner, such having the wrong antenna selected or other less 
than a stellar condition.?? This includes excessive RFI in the shack, or 
common mode current on the feed line.??? Since the bare description was 
"when amp on", clearly indicates a RF power related condition.

Take Jim's, K9YC, advice and be sure every piece of equipment cabinet is 
bonded with a dedicated ground/bonding jumper.??? Also, it may be 
necessary to have common mode chokes at the antenna feed point.

The bottom line as I see it, it is not specifically equipment related 
but more so of the station installation and configuration.

Legally, and it has always been this way, one should use only the 
necessary power with mode to effectively communicate.? I suppose ones 
lacking translation and understanding is "to effectively communicate". ? 
Hams need to understand how to operate smarter and not "with more 
power".? Any idiot can plunk down several $K and operate with more

Mark,

Did you measure C44 and C46 through the entire range of rotation? and 
what is the color of the plastic bodies?
The last I knew, they were about 20pF maximum and the bodies were red.? 
The others do not have a sufficiently low capacity to tune 12 meters.

Similarly for C21 and C23 which the last I knew were yellow or brown.

If those capacitor pairs are swapped, you would have the problems you 
describe.

73,
Don W3FPR

Welcome to the land of unintended consequences.? To my personal dismay these 
modes have taken off in the DX chasing biz.? (I have a friend who has been on 
many many big-time DXpeditions and is giddy about using FT8, since the DX end 
can sit back and drink coffee). Show me a DXer who doesn't want to break the 
pile up first and you'll be showing an anomaly. Contesters are the same.

Fox and Hound requires the lower frequencies so tuning the dial higher isn't an 
option.? I also suspect that these guys are using limited BW and don't hear the 
higher tones anyway.

If Joe wants to propose things (a sub-band is unenforceable*) why not a separate 
award for FT DXCC?? I have DXCC on RTTY and refuse to add FT QSOs to my total.? 
They are different things.? RTTY requires some skill.

* During the recent HD8R DXpedition they operated on 60-meters; on "channels" 
not available to US hams.? Furthermore they operated split, with their listen 
frequency even further from a legal channel.? With a little forethought they 
could have listened down instead of up and I could have easily worked them.? But 
I did not; however, this didn't stop some lids from working them out-of-band.

This is what I do when running SO2R on FT8/FT4. I ensure that both are on
the same cycle.

This insures no intertransmitter interference.

"I have DXCC on RTTY and refuse to add FT QSOs to my total.  They are different things.  RTTY requires some skill."

You seem to imply that FT modes require no skill.  I disagree.  There are complete LIDS using the modes and there are others who carefully pick TX frequencies to avoid QRM to a QSO in progress and time their transmissions to effectively tail-end without causing QRM.

There are LIDS who work DX and then call CQ on the DX frequency.  Noone with any understanding of the mode would do that.  FT8 is not blast and log.  It does require some thought and it's obvious some on the bands didn't give it any.

FT mode skill is not the same as CQ or RTTY skill but to deny there is a skill to effectively using FT modes is, at best, short sighted.

Andy, k3wyc

I strongly agree, Andy. When folks say that it's the computer that makes 
the QSO, I observe that 1) I know no one who can read RTTY without some 
form of decoder, and 2) the computer did not put up my antennas, build 
my station, learn propagation, learn electronics, physics, transmission 
lines, and so on.

Good Evening,

a bit more listening, I found their CW signals had particular

These times should play well with the SSB nets which are:

1800z  14303.5
1900z   7180
0200z   3775

The 80M net details are in flux because the net before us on the 
frequency observes daylight savings time. Either we will be on 
an hour later, or we will find a new frequency at 0100z. (Watch 
this reflector.)

I wonder if anyone has "Worked all Elecraft Nets" on a single 
Sunday. I have worked 4 of the 5, but the 20M CW net interferes 
with the dinner I'm in charge of cooking, so I haven't been able 
to checkin to that net.

"Please explain "effectively tail-end" using FT8."

To tail end is, at least in my terminology, to call a station at the end of their current QSO without waiting for them to call CQ.

To tail-end effectively means, at least in my terminology, to call the station without causing QRM to their current QSO and have them answer the call.

"Using FT8" should need no explanation.

One essential aspect of tail ending effectively without causing QRM is to NEVER call on the current QSO frequency.

I figured I'd get somebody riled up.? I will give you that a modicum of skill is 
useful in frequency selection.? However, when DXing, the DX station sets the 
sequence, you don't get to pick it.? So the best you can do is to not transmit 
once in a while so you can see the competing callers (if skip allows it). You 
can easily have propagation where you don't hear any of the other callers, so 
that "skill" is really "chance". With F/H I even lose the right to set my TX 
frequency.? On more than one occasion I've had the fox copy me, move me to his 
frequency only to NOT copy me again.? Then I start over.

Forgive me for not understanding tail ending on a mode where the protocol sets 
the timing.

Contrast to traditional RTTY.? What's common, a machine encodes and decodes the 
message.? Otherwise, on RTTY I determine the message content, when to call, 
where to call and I have control of RX QRM fighting features and can run 
multiple decoders.

Just to keep this somewhat Elecraft related I will say that even though I've 
moved to a Kenwood TS-890 for a number of reasons, my K3 and K3S are the better 
RTTY radios.

NEVER call on the current QSO frequency.

which can easily be done by looking at the waterfall... and moving the 
TX ( red)? bracket to a open area on the waterfall...

which, while not guaranteeing the freq is open at the other end, at 
least it's open at your side....

You are confusing "operating practice" with "skill". A skill is something
that takes time & practice to learn. The poor operating procedures you
describe could be solved with nothing more than an explanation to the
offender.

I'm aware of the concept of tail-ending. I was wondering how it could be 
applied in the context of FT8 which has a proscribed timing structure.

If I'm S&P I wait until I see a 73 or RR73 and immediately enable TX. 
The timing is then determined by the PC clock. An exchange or not is 
determined by the inclination of the station called. Then it is down to 
chair time.

Most of the time when I come on FT8 it turns into a pile-up. I can have 
anything up to and beyond 10-15 minutes of callers backed up, that is 
the wsjt-x right hand window goes solid pink. Sounds great but can 
become very tedious. When I send 73 or RR73 running a pile the following 
period is used to determine who to call next and that isn't necessarily 
the newly decoded tail ender who sends his call once and expects to be 
answered immediately. What about the guy who has been waiting for ten 
minutes, the one I have already loaded into the TX sequence. The tail 
ender joins the list. Often, if not answered within a cycle or two they 
can be seen calling someone else, left hand window.

The issue from the sharp end is that you can see who has been hanging in 
and the choice has to be made who to make happy and who to disappoint. 
You can only hope they will continue hang in there. A LoTW using W7 in 
WY is another thing altogether. No contest.

So really it comes down to luck of the draw. However, I freely accept 
that VP8/F has a slight edge.

Running an RTTY pile, what I'm looking for is a clean pair of tram lines 
and will happily hop about the audio passband if necessary. Not running 
a multi channel decoder, unlike FT8, means that I have no prior 
knowledge who the caller is until I land on them. What works for me 
running a pile, the tricks of the trade if you will, also seems to work 
for others and after a few minutes watching and learning this has 
enabled me make the QSO with a feeling of smug satisfaction whilst 
others are still blindly calling without success. A modest #266 (RTTY) 
DXCC leads me to believe I'm doing something right.

On topic. All this has been achieved using K3 #00345 much modded and 
upgraded. A bigger investment over time than a shiny K4.

Mike VP8NO

That's how tail-ending works with FT8 and similar modes. I've used it 
many times.

Re; Tail-ending,? He who hesitates is lost, or as a Navy sky diver once told me, 
"He who hesitates shall inherit the Earth."

Classic tail-ending is calling BEFORE the last guy is finished.? So while the 
previous guy is sending 73, good bye, hasta la vista, hope to work you again 
soon, you snuggle up to the frequency, drop your call in and work the DX while 
the other guy is still sending.

This is all dependent on paying attention to how the DX handles pileups. Some 
don't like this.? So listening is always important. For example, I worked one 
major DXpedition (forgot which one but their leader was the keynote speaker at 
Visalia the next year and mentioned exactly this).? They were calling CQ on 
14.190 and the op would say, "Listening 200 to 210" and the pile would instantly 
begin screaming as he paused ever so slightly and continued "and 14.195." I 
worked him on 14.195 on one call.

Subject: [Elecraft] K3s not transmitting AFSK
Message-ID: <9ec64ba1-d6e1-c136-57c1-43668284348c@mdodd.com>

Here I am in the middle of WAE RTTY, and suddenly my K3s is not 
transmitting RF on AFSK A. Here's my configuration:

* Built-in USB sound card
* N1MM+ with MMTTY engine
* MODE is set to DATA
* DATA MD set to AFSK A
* PWR is set to 100W
* LCD and MMTTY decode RTTY signals correctly
* TEST mode is off

Everything was working perfectly five hours ago when I turned off the 
rig. Now I turned on the rig again and launched N1MM+. If I press F4 (my 
call) the transmitter keys (TX light is on) and produces RTTY tones that 
I hear and that MMTTY decodes and displays. But no RF comes out of the 
rig. The RF meter has one bar at 0.

Does anyone have any idea what's going on? Should I reload the firmware?

Thanks

Message-ID: <9b994e7a-c5a8-5b51-03a4-2981b4c36b44@mdodd.com>

It's all working now, and I can't explain why.

Rich VE3KI sent me a suggestion off-list to try the Windows 10 Sound 
Control Panel.

The ONLY thing I did there was select the USB CODEC, check that the 
playback level was not 0, and click the Test Device button. That 
produced a few tones, and the K3 produced 100W into a dummy load in the 
DATA mode, just as it should.

I launched N1MM with the Digital window open, and pressing F4 sent my 
call, and the K3 again produced RF.

So I switched back to the Carolina Windom antenna and worked LA1TV on 
15M with the KPA500 pumping out 300W.

Bottom line: The K3 was not producing RF in DATA mode when I started 
this morning, then produced RF after I tested the USB CODEC in Sound 
Control Panel. I have no clue why.

Thanks again to everyone who offered advice.

Message-ID: <20211114145001.Horde.uBk7VnwYtrGqqIpLwb4rogG@www14.qth.com>

Fellow Elecrafters,

After the recent time change, we found that when attempting to meet at  
0100 UTC, which now comes out to 8pm EST, there were several other  
nets running on and around our chosen net frequency of 3775 kHz.

I listened until after 9pm EST, which was our normal time during  
daylight time, and the frequency was clear, as we have experienced  
this past summer.

So, let's all try meeting this evening (Sunday local) at 0200 UTC,  
which will come out to 9pm EST/6pm PST.

See you on 3775 kHz, USB!

73,

Well, we had one check in this evening, besides myself.  Steve, WM6P,  
said that he could barely copy me, so perhaps the propagation was off,  
and of course, we tried changing the UTC time which may have confused  
some.  I have a standing conflict at 8pm local time on a local 2 meter  
repeater ARPSC net, so I'd prefer to keep this net at 9PM ET, summer  
time or not.

I guess we'll see.  Opinions, options?

Here is the checking roster for this evening:

WM6P      Steve      K3s      KPA1500
N8SBE     Dave       K3s      KPA500     Net control

Well, I cut out the existing U4 MAX1406 chip on the KPA100 and soldered in a 16-pin socket. Putting in a new MAX1406 chip in the newly installed socket and ? same problem as before. The radio does not respond to commands, pressing the PORT TEST does not result in any data output.

I haven?t had a chance to put a scope on the pins yet to see what is happening. 

I do find it odd that the pulse trains were reaching the CPU earlier, but it was not acting on the commands. (eg RT1; would not turn on the RIT, RT0; would not turn off the RIT)

Any suggestions or ideas on how to debug this further?

Message-ID: <000001d7db03$04222390$0c666ab0$@aya.yale.edu>

Has anyone been using a K2 to drive a KPA1500?  I've read the KPA1500 manual
and the just-released notes on using CI-V protocol transceivers, all of
which seems straightforward enough, on paper.  I would nonetheless
appreciate hearing from someone who has done it - about unexpected issues,
results, frustrations if any, etc.  My latest K2, for example, does not yet
have the KIO installed. Should I do that before even trying anything else?  

 

Thanks, for any thoughts or advice,

 

Ted, KN1CBR

Bill,

Plug the ribbon cable in and do an end to end continuity test - KPA100 
U4 pin 12 to Control Board U6 pin 25,
And KPA100 U4 pin 11 to CB U6 pin 26.? That will check the board wiring 
and the ribbon cable.

If all that is OK, try replacing CB U6.

Don W3FPR

Ted,

The 9 pin connector on the KIO2 is not compatible with the signals 
required by either amplifier.? You will be better off using only the PA 
Amp Keying from the K2.
That Amp Keying output is not standard on the K2, but I believe Dave Van 
Wallaghen W8FGU is making up kits.? Send an email to Dave at W8FGU.com 
to ask.

Don W3FPR

That is for tightening the little screw in your head if you ever decide to get rid of the rig.

You need to gently slide the large rubber band off the VFO A knob to
access the single allen screw. The band can slide back on the knob
with some slight stretching.

Is an ?Elecraft style? full manual planned for the K4? The K4 introductory manual that was in the box with my new K4 is really more of a feature brochure, and the electronic document internal to the K4 is more thorough than the introduction manual but still a lot less detail than what I got with the K3 and KX3. One of the things I have always liked and admired about Elecraft is they have always provided fantastic owner?s manuals.

We're updating and expanding both manuals as time permits. For the operating manual, we're prioritizing documentation of new features and troubleshooting tips as they come up. The Introduction manual is about to get a new block diagram, etc.

Message-ID: <2203dc0f-c48c-aaa0-817a-4da0ec029016@inkbox.net>

If the K3S is placed in TEST mode for the purpose of CW practice without 
transmitting, is the CW audio available on the rear panel's Line Out 
jack? Or can it be sent there via a menu setting?

For the purpose of a Zoom meeting, I'd like to send CW practice audio to 
an external USB audio interface that expects a line input. If that's not 
feasible using the K3S's Line Out port, I suppose it might be pulled 
from the headphone jack? If so, is there anything I should be looking at 
doing to adapt it to the audio interface's line input?

Thanks much,

Frank K6FOD

The K3S does transmit in Test mode. I've seen 50W of output from my KPA500, 
while in Test mode.

I mentioned this on the reflector on 7/25/2017, topic "Test Mode Garbage."

Might this have been since fixed in firmware?

Didn't see an answer to the question.

I can confirm that my K3 with USB upgrade does output the CW side tone 
audio. This was confirmed by Launching Logger32 and looking at the audio 
in the MMTTY RX waterfall display.

A simple test that probably took less time than launching an email.

For completeness I thought I would copy my original message for the doubters.

"I received an email from a German ham telling me that he's observing the same 
thing that I reported a couple of years ago. Specifically an audible "clicking" 
sound in both my K3S and KPA500 that coincides with CW keying.? See this thread: 
http://elecraft.365791.n2.nabble.com/KPA500-clicking-td7596512.html

Since there was no "fix" from Elecraft I guess time dulled my sensitivity to it 
until I received the email and then I thought to listen for it again.? It's 
thunderstorm season here in the AZ desert so my antenna cables are all 
disconnected. Because the problem manifests whether or not RF is being generated 
I put the K3S into TX Test mode and put the KPA500 into operate.? As before, the 
clicking is still there in both the K3S and KPA500.

But while doing this I noted that the SWR LEDs on the KAT500 were flashing.? 
Since the antennas are disconnected this would be normal if RF was being 
generated, however as stated, I'm in Test mode.? One of my tuner ports has a 
dummy load attached so I switched to it and lo and behold the amp output LED was 
showing ~50W.

I have an original K3 so I tuned it to the K3S frequency, keyed the K3S and 
listened on the K3.? I could hear a non-coherent, clicky "garbage" signal that 
seemed to have a spectrum roughly the width of the TX filter.? Because both 
radios were running on the same power supply to eliminate the possibility of 
crosstalk via that path I fired up an SDR-IQ running on a totally separate 
computer and looked at the spectrum.? Although it's non-synchronous to the 
keying I can see a signal that does have an envelope roughly shaped like a BPF 
although it's far from flat in the passband.

The amplitude of this is affected by the output power setting and is present 
with the KPA500 in Standby.? It also seems to be thermally sensitive; becoming 
less conspicuous the longer things run."

Wayne replied:

Hi Wes,

TX TEST mode activates the entire TX strip because it turns on PTT to test the keying of downstream devices. This was requested by our original field testers. The only thing that isn?t turned on is the carrier. It could be that in SSB modes there?s noise in the voice passband, producing the result you observed.

I can clarify this in an errata item for the owner?s manual.

It may also be possible for me to disable the TX AF path via a DSP command, and I?ve added that to the firmware task list.

Thanks for the input--

Wayne

U6 is kinda expensive to just replace?.

I do have an older revision of the firmware for U6. I did try before substituting the KPA100 U4, and it didn?t address the issue.

I guess this will require more sleuthing.

Don?t forget, you can?t plug in a USB adapter directly into a K2, as the
wiring is not standard RS232C. You need to make up a special adapter as
described in the manual. Probably you know this already, but just something
else to check.

Matt,

I Forgot to mention that to Bill.? The special cable does not have to be 
very long, but it must be present.? Only pins 2, 3 and 5 should connect 
to the RS232 connector on the USB to serial adapter.? Failure to follow 
this will cause several "strange happenings" with the K2.? The subject 
line said it "quit working", so I assumed it had worked just before it 
quit.

Bill,

What is the level of the MCU (before you changed it), and what level did 
you try putting in?
And what is the serial number of your K2?? Those may help to solve the 
problem.

Subject: [Elecraft] Headphones (Again!)
Message-ID: <406125fa-eff5-c5fe-6789-8242f376d8d4@comcast.net>

I recently purchased a Bose QC-45. I used it for about 5 minutes in a 
CWops contest, and got RF in the left headphone. I disconnected it, and 
returned to my Bose QC-35's. The QC-45's have been returned to Amazon.

I had a similar problem earlier in the year with the Bose 700 
headphones. I tried various toroids, but never could isolate them from 
RF (particularly a problem on 40m). Obviously, this is is not something 
Bose is concerned with. Fortunately, the QC-35 gamer headphones work 
well. With all three headphones, I used the headphone cable (not 
Bluetooth -> delay problem). FWIW, I like the Bose noise cancelling 
because it does a good job attenuating KPA1500 fan noise.

Has anyone used the Sony WH-1000XM3 headphones? How do they work in an 
RF environment?

I recently purchased a Bose QC-45. I used it for about 5 minutes in a CWops contest, and got RF in the left headphone. I disconnected it, and returned to my Bose QC-35's. The QC-45's have been returned to Amazon.I had a similar problem earlier in the year with the Bose 700 headphones. I tried various toroids, but never could isolate them from RF (particularly a problem on 40m). Obviously, this is is not something Bose is concerned with. Fortunately, the QC-35 gamer headphones work well. With all three headphones, I used the headphone cable (not Bluetooth -> delay problem). FWIW, I like the Bose noise cancelling because it does a good job attenuating KPA1500 fan noise.Has anyone used the Sony WH-1000XM3 headphones? How do they work in an RF environment? ? - 73, John, N0TA______________________________________________________________Elecraft mailing listHome: http://mailman.qth.net/mailman/listinfo/elecraftHelp: http://mailman.qth.net/mmfaq.htmPost: mailto:Elecraft at mailman.qth.netThis list hosted by: http://www.qsl.netPlease help support this email list: http://www.qsl.net/donate.htmlMessage delivered to turnbull at net1.ie

Yes, I know. I?ve been using the cable that I built back in 2002, when I added the KPA100, and later modified when I added the KAT100.

Exactly, working one day with WSJT-X, next day, not.

Only pins 2, 3 and 5 should connect to the RS232 connector on the USB to serial adapter.  Failure to follow this will cause several "strange happenings" with the K2.  The subject line said it "quit working", so I assumed it had worked just before it quit.

Serial Number 2548.

The current MCU I have is version 2.04P. (latest)

The unit I swapped in earlier was, I think 2.03. I don?t have it with me, and I?m not sure.

Don,

Managed to do a little diagnosis.

I pulled the MAX1406 chip KPA100 U4.

I see proper continuity between pin 12 of U4 and pin 25 of the MCU, and pin 11 of U4 and pin 26 of the MCU.

Going back, I checked out the Vdd, Vss an Vcc voltages on U4.

Vdd is 14 volts
Vcc is 5 volts
Vss is -5 volts

It looks like, from the specification of the MAX1406 chip, it needs more like -10 volts to work correctly. 

I measured these on the scope before, so I only got vague responses.

I guess I?ll be investigating the Vss supply.

I have the WH1000-MX3. I use them daily but for non-radio stuff. Easily the
best headphones I?ve ever had or used, for comfort and noise cancellation.
They sound great too.
I have used them with my KX2 when traveling, but I don?t think I?ve ever
used them at higher power so can?t comment on RFI or lack thereof.
They are amazing for air travel (not that I?m doing much of that lately).

Alright, I have figured this out.

I?m not sure why I was seeing Vss of -5 volts. I re-checked the negative supply on the KPA100, flowed the solder on D7 and D8. After that, I was seeing almost -24 volts at the Vss pin, without U4 in place. 

With U4 connected and everything hooked up, Vss was more like -15 volts. I?m not sure what was causing it to read -5 volts. 

However, even with all that, it still wasn?t working!

I could see the RS-232 data get all the way to the MCU - Control Board U6, pin 26 using the scope, but the K2 would not react to any commands. 

Also, when using the PORT TEST action on the menu, I saw no data on U6 pin 25. 

But, then I figured it out.

I remembered that the K2 has a setting which changes the origin of the sidetone. Modern K2?s use U8-4 as a default, although early K2s used U6-25 as the default value, as that was the way the sidetone was originally wired.  I wondered if something had happened and this setting had somehow gotten switched.

Sure enough, I found it was set to U6-25. Changing this to the proper value of U8-4, and the serial port operation was completely restored.

I?m not sure how this value got changed. It could have happened if the DISPLAY button had been pressed when the ST L menu was in edit mode. Since ST L is the default, if the user accidentally held the MENU button too long, and then immediately tapped DISPLAY, that would have done it.

Sorry for all the trouble. It really is amazing that something so simple could cause so much bother.

Bill,

In the KPA100, the normal Vss is about -25 volts, so suspect that 
something may be loading that negative supply.
Pull U4 out and measure that voltage again.? If it is still not negative 
enough, you may have? a problem in the T/R switch.? Check for 90 to 150 
volts on the highest voltage end of R11.
If that voltage is OK, look carefully at C34, C35, D7 and D8.

Put MCU 2.04P back in - it won't help with this problem, but there are 
other things it will help with.

Bill,

That was why Elecraft released MCU 2.04r which is exactly the same as 
2.04P, but the sidetone source is locked at U8-4.
That can happen if someone EDITs the ST-L menu and then taps the DISPLAY 
button without exiting the menu first.
Many hours of support time had been spent on the "I lost the sidetone" 
problem - so 2.04r was the solution to that problem.

I've heard unsubstantiated tales that a KX2 is in operation at Mayotte.
He's on 21.001 (listening up 2) now (1915Z) with a decent signal into W5.
Smallish pile-up given the Rarity Factor.

Subject: [Elecraft] KIO2 problem -- maybe
Message-ID: <CAKynJKmPTwZ_1Rbg6OS12TTC3RBXQ+jSzbFuz=Rp8ROuSO5Row@mail.gmail.com>

I had a lightning strike and am getting things back together.  I am
attempting to connect via a KUSB cable with a series adapter to make it a
proper cable for the K2.

The PORT menus says the port is ON and I can turn it ON and OFF as outlined
in the manual.

Prior to the strike, this same radio and cable and software was operating
normally.  Now the software cannot connect to the radio, even though the
setup shows an available USB/serial port available.

I'm wondering if the KUSB cable is bad(probably due to the strike)?

First item I need to know, is the KIO2 OK if I can turn it on and off from
the EDIT menu?  If the KIO2 is good, then it has to be the KUSB cable.

What say ye?

Thanks,

Dave, K4TO

I agree.? I had a strike zap the KIO3 in my K3 because even though all 
my other gear was unplugged at the time, my laptop (which interfaces to 
my K3) wasn't. ? at first thought it was the KUSB.? I bought a second 
one figuring it wouldn't hurt to have a spare if the cable turned out to 
not be the problem ... which it wasn't.

I checked with Elecraft tech support via email to see if individual KIO3 
boards were available, or if mine could be repaired.? They didn't answer 
either of those questions and the sole brief answer was "you should just 
buy the new USB version".? Which cost about $400, of course.

Don, W3FPR, ended up selling me a set of the three boards he had 
replaced for somebody upgrading to the newer boards.? One of those was 
even bad, but luckily not the serial one I needed.? Swapping out the 
serial board by itself fixed the problem.

Dave,

Being a little 'tongue in cheek' the answer is -- That depends on what 
you mean by "good"!
Seriously, the fact that you can turn it on and off in the menu only 
means that there is a response from the KIO2 when it is communicating 
with the MCU over the AUXBUS line.
I would suspect the MAX1406 IC, but since there was a lightning strike, 
it could be something different - anything!

First do all the voltage measurements on the KIO2 board.
Does anything get hot?? The voltage regulator in particular.
Are you using the "special cable" between the KIO2 and the KUSB cable?? 
You MUST use that!? It does not have to be long, but must be present.
Check that all the inductors show continuity.

If none of that is revealing, I can give you a series of tests that you 
can do to test the KIO2 alone (without removing it).
If we get to that point, take it off-list (Delete "[Elecraft]" from the 
subject line) and I can give you the steps via private email.

Don W3FPR

Eric,

The schematic for the KXV3B-2 BNC Board
shows a COR and associated RF detector
circuitry for the RX ANT IN port.  There
is also a protective spark gap on that
input, presumably for lightning induced
voltages on the RX antenna.

I haven't checked the K3s manual,
but the RF detector circuit uses
a Schottky rectifier/peak detector
circuit to switch an NPN Darlington
pair that controls the COR coil.  I
estimate about 1.5 volts peak
RF on the RX ANT input would
trigger the COR and disconnect
the RX ANT input from the rest
of the RX signal processing chain.

FWIW, I have been using Heil Pro 7 headphones successfully for years. I use cw 95% of the time, including during quite a few enjoyable CWT events. I only occassionally use the mic and ssb mode. I own several pair that I use with their specific radios. I use them on my Elecraft K2, and KX2, my Yaesu FTDX3000D, and my LNR Mountaintopper 3, 4, and 5b transceivers.  I never have the slightest RF or feedback.  They are well worth buying and using.  I highly recommend them.  The radios without ssb, I don?t use the mic or mic plug but instead I keep it secured out of the way.

My k3 keeps losing its mind. One day it won't transmit SSB - I can whistle
up 100W but speech gives 5W of avg and ~15W peak.
On another day it says "KAT500 not turned ON". I have a KPA500 but no
KAT500.
My fix for both these has been to do a factory reset and reload my last
saved configuration -- not something you want to do in the middle of a

Any ideas on what might be causing its lapse into insanity?

I have used the Heil Pro 7 also.  While they displayed no RFI issues, they
fall far behind the Bose QC35s,  Radiosport, and even Bose QC25s in keeping
out KPA1500 fan noise.  They worked FB for me in the CQWW SSB test, where
the KPA1500 fans rarely turn on, and never get louder than FAN1 at my
station, running at 1300w out per LP100A mearurement

I had a similar failure several years ago.  Don helped me troubleshoot that
little board and the problem turned out to be a few diodes that got blown
due to a lightning strike.  I was glad it took out the diodes and not the
K2.

I do not use a KUSB converter with the K2 as I have 'real' RS232 ports in
the shack computer.  Since that time, though, I have used a wireless link
between the internet box (also taken out by lightning) and my shack
computer. This removes one path for any future strikes to come through and
blow up my modest shack.

GL on fixing your problem, Dave.  It's worth the time.

Dick,

Sorry to hear you are having issues, and I know this does not fix your 
current issue, but as an aside, I always do a save of system config just 
before any critical operations like contests, etc.  Makes the recovery a 
lot simpler, if needed.

73, and thanks,

Message-ID: <CAEVEBrMCo5NyPE2A2hBFf2Tp5sq3jKVpTSDT1oEq=ERzFeP4Hg@mail.gmail.com>

Hi folks,

I was tinkering with a whip + counterpoise antenna connected to my KX3 by a
short stretch of coax with BNC connectors a couple nights ago, and
discovered (painfully) that there was quite a bit of RF coming back along
the ground when I bumped the outside of the antenna connector. I know from
experience that the KXPD3 can end up tingly in turn, and I'd like to avoid
that.

If this were a fixed antenna, I'd just slap one of the LDG RU-1:1 ununs on
it as a choke, but they're pretty chunky -- they're rated for 100 W CW, and
have SO-239 connectors, which would require adapters on both sides in this
setup.

Does anyone know of a choke more appropriate for this kind of setup? I'd
prefer something smaller (rated for maybe ~40-50 W continuous?) and
natively BNC, so I don't need to juggle adapters.

More broadly, is this the appropriate way to fix this problem? This was
with the counterpoise extended as best I could, and with the radio powered
from mains (which may have actually made the problem *worse* by providing a
more attractive path than the counterpoise?).

(As an aside, when components like baluns/ununs or tuners are rated as "100
W CW, 200 W SSB", do they mean literally a continuous wave, or do they mean
CW at a standard Morse duty cycle of roughly 50%?)

Thanks and 73,

Julie

I use a large ferrite clamp-on to isolate my short whip/counterpoise from my KX2. Needed tor running digital modes. The large variety will hold 3 turns of RG-58 which seems to be enough for what I need. IIRC I got them from ProAudio Engineering. GL

Make a choke with RG-316 - small size and can handle quite a lot of power.

The problem occurs when the counterpoise doesn't provide a low impedance 
path for RF. If the problem occurs on a specific band, then try a 
counterpoise that is about 1/4 wavelength long on that band. You can add 
one in addition to the existing counterpoise, if that one is working 
properly on the other bands. You might have to play with it because the 
appropriate length of a wire lying on the ground will not be the same as 
one in the air.

Regarding ratings, you are lucky if "100w CW" actually means 100 watts 
at 50% duty cycle! It certainly doesn't mean 100w continuous.

Hi Julie,

A unun is an auto-transformer, not a choke. It is a matching device.

Does your antenna include a counterpoise?  It should -- it's a critical 
half of of an end-fed antenna, carrying return current. Without it, 
return current flows on whatever wiring is connected to your rig, and 
what that's connected to, which SHOULD be Ground, at minimum via the 
Green wire at the power outlet.

73, Jim K9YC

I don't normally operate phone, but wanted to contribute a few QSOs to

K3's monitor.? So then I plugged my Yamaha CM-500 condenser mike headset

OK, but there was a very high level of white noise, audible both with 
live voice and while playing recorded contest messages.? I was reading 
700 watts out without talking.

Experimenting, I discovered that the source of the noise was definitely 
the mike on the rear microphone jack.? I also didn't like the fact that 
in this setup the mike was live while recorded messages were playing.

How can I rig things so that the mike doesn't contribute this high level 
of background noise, and how can I manage things so that the microphone 
is muted when the recorded messages are playing through the line in jack.

Hi, Pete. Try a dynamic mic or use the front panel (ugh) mic connector.
I've had RFI problems at high power using a CM-500 on the rear panel mic
jack. Elecraft are working on a fix. My Heil headset with dynamic mic works
fine.

I also had RF problems with the CM-500 plugged into the rear mic jack.  The solution I?ve implemented so far was to wrap about 13 turns of the CM-500?s cord around a #31 toroid. It both shortened the cord which was way too long for my shack and eliminated the RF problem. A two-for-one solution. ;-)

On rare occasions I like to use my D-104 mic in the front panel jack.  It too is adversely affected with RF issues.  As soon as I get a moment I?m going to try wrapping it?s cord around a #31 toroid and hope it works as well there as with the CM-500.

I hope Elecraft is looking at the front panel mic jack as well as the rear when looking at solving the RF issue.

Interesting. I tried a ferrite and, although it reduced the problem, it
didn't cure it. I'm not sure it was a #31 mix, though, and I didn't wrap
that many turns. Will try again. Sure wish toroids were labeled!

Thanks,

Good Evening,

 ?? A few months ago I cleaned out my weight room and added a 
workbench.? I use it to rebuild my computers.? I moved one of the 
servers in too.? That keeps the room and the weights warm.? I no longer 
have to wear gloves to lift in the winter.? Now, to get the other two 
servers in there so their heat is useful too.

 ?? The twenty meter net was more difficult than I had expected. Signals 
were weak, QRN was moderate, and QSB was too.? Roy mentioned the sun was 
setting at his home.? I may need to move that net earlier.? The forty 
meter net was better, stronger signals with less QSB.? On twenty it was 
slow around 3 S units deep.? On forty it was faster but less deep, about 
1 S unit.? I did start guarding the frequency early but signals stayed 
strong until I ran out of check ins.? 0030z will work for ECN/40, maybe 
ECN/20 should start around 2230z next week.

He played it left hand
But made it too far
Became the special man
Then we were Ziggy's band

Ziggy really sang
Screwed up eyes and screwed down hairdo
Like some cat from Japan
He could kill 'em by smiling
He could leave 'em to hang
He came on so loaded, man,
Well hung, snow white tan

So where were the spiders
While the fly tried to break our bones?
Just the beer light to guide us
So we bitched about his fans

I don't think RFI is implicated.? I can hear the loud background noise 
even with the RF turned way down.? This is something else, I believe, 
perhaps something about the way the gain is distributed, or???

Hi Pete,

I suspect you may be right. When feeding computer audio to the Line 
Input, the Mic Gain knob becomes Line In Gain, but Line In Gain must be 
adjusted with Line In selected, Mic Gain must be selected with Mic, 
selected, then switch to Mic + Line to operate. I suspect one or the 
other of the two may be set too high.

OR -- output from the computer itself may be set too low, so it may have 
been necessary to turn Line up very high, and you're hearing noise from 
the computer's output.

If I wasn't the first, I was the second, person to recommend the CM-500.? I've 
used them on both my original K3 and a new K3S.? IIRC I've gone through three of 
them; buying new ones when the pads wear out.? I have never had RFI issues with 
them (or anything else for that matter).? The only ferrite in my shack is the 
stuff molded on some of the computer cables I use.? I wish my TS-890 had the 
same rear-panel capability as the K3(S) for using these.

As far as I know, W6XU, who runs a consumer/semi-pro audio mfg biz, 
introduced the CM500 to ham radio with a large group purchase for the 
Northern California Contest Club. I'm guessing around '08 -- I'm sure it 
was after the first K3s hit the street.

Like you, I've passed along the recommendation many times, and like you, 
I've had to buy several replacements. I've never had a problem with the 
ear pads. My failures are all broken cables, primarily because I've 
always been a real klutz.

Richard,

During DX SSB contests, DX tends to transmit below 7125 kHz (where US  
cannot transmit SSB) and listen above, sometimes above 7200 kHz, so I  
tend to tune a 40 meter antenna to the center of the band 7150 kHz,  
and use the internal tuner in the radio to 'touch up' the SWR near the  
upper and lower band edges.  The important thing, to me, is to keep  
the transmitter happy, so it doesn't 'fold back' when the SWR goes  
above 1.5:1.  If the coax is not too long, and is not too lossy (and  
at 40 meters, it really shouldn't have much loss), you won't lose much  
by tuning at the radio end, to match the coax to the transmitter.

I use a ZS6BKW dipole and tune it at the radio end for use on 40/60/80  
meters with a 75 ft. piece of RG-8/X coax.  It is only 35 ft. high, so  
it is much more useful stateside, but nevertheless I don't sweat the  
additional loss due to higher SWR on the coax at those frequencies.

Donning flame suit...

73,

-- Dave, N8SBE

Yes, I kind of think you are right, Jim.? I did not know about the 
requirement to set Lin In with Lin In selected, and Mic Gain with Mic 
selected.? I had been doing adjustments in Mic+Lin with the front panel 
Mic Gain only, assuming that in Mic +Lin it controlled both.? Whew - 
good to know it's not something wrong.

I have had two cable failures, both happening inside the side with the 
microphone. While it's not initially obvious, you can pull the earpad 
back far enough to get at the three small screws that hold the back part 
of the headphone on.

There is no simple answer to your question. Most DX stations will be below
7.200MHz however many Caribbean stations will be higher in the band. Also
some DX stations operate split and listen above 7.200MHz. So it's best to
find a way to cover the whole band.

Is there any area within the 40-meter SSB segment where DX tends to
congregate or appear? I ask this for antenna tuning purposes.

A half-wave dipole tuned to resonate in the middle of the band will have 
very manageable VSWR over the entire band.

Subject: [Elecraft] Announcing the Elecraft AX2 miniature 20 meter whip
	antenna
Message-ID: <A0FED84A-EA9F-4751-A921-1A24C844D9EC@elecraft.com>

Our AX1 dual band whip has become a favorite of HF portable operators who travel light?especially those engaging in /PM (pedestrian mobile) operation. 

Now we?ve created an even more compact whip: the single-band (20 m) AX2. It uses the same telescoping whip as the AX1 (6? collapsed). And like the AX1, the whip and base unit can be quickly disassembled for transport. 

But the AX2 takes portability to the next level, with a base unit that?s only 2.5? long. The AX2?s base also has much lower wind load, and is designed to completely eliminate wobble at the BNC connector. 

Best of all, the AX2 can be modified for use on any band from 17 through 6 meters by removing turns from its high-Q toroidal inductor. (Soldering required.) With renewed solar activity, the higher bands are becoming more active, often with low noise conditions ideal for SOTA as well general QRP operation. 

For full details, see: 

https://elecraft.com/products/ax2-minature-20-meter-whip-antenna

Limited quantities of the AX2 are available now. 

Note: As with other electrically short loaded antennas, the AX2?s resonant frequency will vary with terrain, height above ground, counterpoise position, body capacitance, etc. For this reason an ATU is required for transmit purposes; this will also improve sensitivity on receive. The Elecraft KX2 and KX3 both have wide-range ATUs suitable for this purpose, allowing instant one-touch retuning as conditions change. An Elecraft T1 ATU may also be used. 

Join in the fun of ultralight HF operation with our new AX2!

Good morning.  I'd like to buy & make a K2 kit but would appreciate advice on what features to buy.  I'm a simple chap based in the UK. And after 50 years I now Only use CW on 40m with a straight key,   and I don't bother with contests as the morse is all autokeyers, keyboards, decoders, & 30wpm PFKeys.  No criticism intended it's the inevitable evolution of CW with technology.  I have a long wire resonant (SWR < 1.4) across the 40 band hence don't need an ATU. I've consigned my ICOM kit to a box in the attic and now use an early generation K2, battery powered, at 10W.  But I'd rather like to build a new K2. I'd need roofing filters etc for CW but Not SSB or anything else.   What would also be nice would be a panadapter but not sure how that would connect. Any advice/guidance would be much appreciated. ??? Ted M5UF

Hi Ted,

It sounds like all you would need is a simple configuration for your K2. 
A couple of things you may want to consider is the KNB2 noise blanker if 
you happen to have any impulse noise issues at your QTH. Also, the KAF2 
audio filter provides a set of nice audio filters that can be peaked at 
your sidetone frequency and help weak CW signals pop out of the noise.

You will have a set of 4, voltage controlled (adjustable) CW crystal 
filters. They can be set at any width you like and centered on your 
sidetone frequency. Typically they are set for widths of 1.5kHz, 700hz, 
400Hz and 200Hz. But you can choose whatever works for you. There is an 
older program out there called Spectrogram that makes setting up you 
filters a snap. You feed the K2 audio into your PC's soundcard and 
display the audio spectrum using Spectrogram to visually adjust the 
width and center frequency of your 4 filters.

A panadapter solution is not inherit in the K2. But, with the addition 
of a IF Buffer amplifier, the K2's IF can be brought outside the K2 for 
use with various solutions. I came up with a nice panadapter solution 
that uses an IF amp designed by Jack Smith, K8ZOA (SK) and sold by DX 
Engineering. I feed the IF output to a SDR Play unit and use HDSDR on a 
PC to display spectrum and provide point and click QSY via Omni-Rig. 
Here is a complete write up of the project on my site: 
https://www.w8fgu.com/k2pan.html

If you decide to implement a panadapter solution or need rig control 
from a PC, you will also need the KIO2 Aux I/O board in your K2 to 
provide RS-232 communication. Another consideration may be the K160RX 
module. Although it doesn't sound like you would need 160m capability, 
the module also provides a separate receive antenna port that can be 
used on any band if you have the need to use a separate RX antenna. 
Based on your operating preferences, it doesn't sound like the KSB2, 
KAT2 or KBT2 (internal battery) would be useful to you.

Hope this helps.

73,
Dave, W8FGU

I found when I built a single wire dipole for 40M it didn't have 
a low enough SWR across the band for my preferences at the time. 
I fixed the problem by using two wires, spaced about 10cm, 4" 
apart for the elements. They join in the middle at the common 
mode choke and just loop back at the ends. This lowers the Q of 
the antenna enough so it satisfied my SWR goals.

The failure that lead me to a new CM-500 was a broken microphone 
attachment to the headphone. If I was CW/digital only, no 
microphone might be an improvement. :-)

BTW, I got the replacement from B&H sales who listed it as a 
dynamic microphone. It isn't dynamic. It is electret and 
requires a "bias" voltage either from the radio or using the 
supplied battery holder.

Message-ID: <d2ca6365-6337-98f2-8e05-f256140bf460@inkbox.net>

After not having used my KX3 in a while, today I set it up with a laptop 
on the front porch to send FT8 in WSJT-X with a new AX1 antenna.

I went through the procedure in Don W3FPR's document "Setting Elecraft 
Transceivers for soundcard digital," setting in and out audio levels on 
my MacBook Pro for the thumbnail-sized Sabrent USB soundcard; Mic Gain 
on the KX3; and the power slider in WSJT-X. CAT control is working fine, 
and the KX3 is in DATA A mode. The waterfall of incoming signals appears 
normal.

I seem to be getting a good signal out, with -1 dB reported from Alaska, 
and -7 to -10 dB from the U.S. east coast with the above settings around 
midrange, and with the KX3 set for 15w out. However, I don't see any 
bars at all on the ALC meter at any time, even when the USB soundcard 
out, KX3 Mic Gain and WSJT-X power slider are set as high as their maximums.

Am I forgetting a setting? Anything I can look at to troubleshoot the 
ALC meter function?

Thanks much,

purpose, maybe there still are. Google knows ... try "cage dipoles".? 
You will get even wider BW with 4 wires in a square, 6 in a hexagon, or 
more in a circle although the marginal benefit of another wire in the 
cage decreases as the number of wires increases.? The humongous antenna 
for the Duga Russian Woodpecker OTHR used cage elements.

The cross and star insulators were great for building multi-band 
coupled-resonator antennas.? They're quite a bit easier to get adjusted 
than fan-dipoles, I built one for 30/17/12 right after we got those 
bands.? Google knows about C-R antennas too.

A classic problem.  You have TOO MUCH input gain.  Counterintuitively the KX 3 ALC will display nothing if over driven.  Turn the input way down and then increase in small steps.  You will find the right setting to show ALC that way.

Does anyone know *why* it does that? It's confusing when no bars means
either "way too high" or "way too low".

Looking for ideas for a cheap 14 volt wall wart type power supply for recharging the KBT2 battery. Is there one available that has the right plug? I see lots of 12 volt and 14.4 volt chargers out there, but???

Thanks, Doug, W0UHU.

It?s a self protection feature to keep you from blowing up the audio input. The KX2 has it as well. Causes me to scratch my head until I remember.

Sure, but when it engages, why doesn't it show full bars, or flash them, or
say "HI MIC" or something?

I use a small wall wart type lead acid battery charger/maintainer as the type used for moto and lawn equipment.? I use a Battery Tender brand charger I got many years ago. You might check out their line, which starts at $45.? Similar cheaper chargers can be found on line.? I've never evaluated these for RFI, but I've never had an RFI prob that I traced to the charger, which is in the garage.

With such an out of balance antenna, the case, power supply and leads of 
the transmitter are all going to be parts of the real antenna.  I'm not 
sure, therefore, that  you can rely on an SWR measurement made using 
other equipment.

You should certainly make sure that paint is removed from inside the 
panels around where the 2-d fasteners go, to maximise the RF integrity 
of the outside of the case.  As you are not using a microphone, you 
probably don't need to bond signal ground to the case there, as well

Hi Doug,

I use this, and it seems to be working very well.  When you order, make
sure you specify a 14.8V (or 14.6V) model.

Some reviews complain that the voltage measurement is only 12V, but mine
clearly shows 14.8V on my Fluke meter.

Running my K3S, KPA500 and working 160M - 6M at 500 watts, using either 
a mike into the front of the radio, or my headset into the back, I 
experience NO RFI issues.? I don't have any toroids on any cables 
either.?? I also run digital modes with a single USB cable between the 
computer and the radio.? All of these inputs/output stay connected all 
of the time.

As to using toroids, refer to the work that Jim, K9YC has written and

Hi,

I have 50 macros programmed into one P3, and want to move them to a 
different P3.

Does anyone know of a way to move the macros programmed into one P3, to 
a different P3, not by simply retyping them into the new P3?

Subject: [Elecraft] XV50 Rev B - Questions
Message-ID: <7b77802d-1f56-ef52-d5e3-78a6aa021614@icloud.com>

Hello - I recently purchased an XV50 to use with my K2. While setting it 
up for a K2 with no K60XV per the manual, I noticed that there is no 
JP9, where I am supposed to short pins 1-2. On closer inspection, my 
XV50 has a rev B board and it appears these pins don't exist. The 
assembly manual I found online is for a Rev E board and owners manual is 
for Rev F1.

I'm assuming all the other jumper settings from the Rev E manual are 
correct for my Rev B XV50, but I thought I'd ask here for clarification 
before I damage my XV50, since it's almost irreplaceable now days. Also 
a Christmas wish would be to purchase a K60XV if anyone has one laying 
around that they'd be willing to sell.

Thanks, 73,

Brian - KM6ZX

I don?t disagree with K4TAX.  It?s up to the operator to work out RFI at one?s station.

But for the sake of clarity to those that may read this thread later?

The rigs in question in this part of the thread are the K4.

Every component of my station is bounded and grounded per K9YC?s publications. My antennas are effectively common mode choked both at the feed point and at the entry point to the shack (the latter demonstrably reduces received noise at my noisy QTH).

I am unaffected by RF at the operating position in the sense that I don?t get burned and none of my peripherals (such as a PC and monitors, for example) display any evidence of RF at all. The only issue here is what appears to be RF feedback getting into the audio when using a CM-500 plugged into the rear panel mic jack and, as I discovered later, a D-104 plugged into the front jack. Neither mic is shielded and neither uses twisted-pairs in their cables, so it is possible that at least some of the problem lies not with the station but the mics themselves.  Quite interestingly, another mic didn?t exhibit the problem here at this same station.

So is there RF at my operating position?  Well to state the obvious, I guess there must be at least a little or else this would not happen.  But until I find where it?s coming from, a "band-aid? (common mode choke) is an appropriate way to continue safe operation.  This band-aid may also be appropriate to augment components that can?t readily be fixed otherwise.

My comment about Elecraft looking at the radio for RFI issues was solely in response to another post in this thread where it was stated that Elecraft was ALREADY looking into the rear panel mic jack for RFI, which made me wonder if there was a known problem. IF that is true, then maybe looking at the front panel jack may be advisable. Otherwise I agree it?s not up to Elecraft to work out RFI issues at an individual?s station.

Dave - N5DCH

Have you checked it for noise, using techniques in this app note?

Most hams have so much receive noise that they can't hear. If you 
haven't gone through your home to get rid of your own noise sources, 
chances are you're one of them.

Hi Jim,

Excellent article.  I haven't checked if it is a source of noise, but it
doesn't quite matter because this is a charger, not a power supply.  I only
use it when I need to charge a battery, so it is OK.

Best 73,

Although you can certainly use it just for charging an SLA, one advantage of these types of chargers is they automatically go into float mode to maintain the charge and prolong the life of the battery.? This is particularly beneficial for batteries that go fairly long periods of disuse, like motorcycles in the winter, or snow thrower batteries in the summer, etc.
I don't doubt that they can put out RFI, but in chasing down RFI at my QTH, which included switching off the power to the entire home, the ones I use (Battery Tender brand) were never identified as causing me any problems. Of course YMMV.

Brian,

In later XV transverters, JP9 controls when the crystal oven is powered.
Since you do not have JP9, even if you have a crystal oven, it will 
still work fine.
The oven will be powered when the XV50 is powered.? Just allow some time 
for it to warm up (about 20 minutes).
Actually, the 22MHz crystal does not drift much and usually does not 
require the oven.

73 and Happy Thanksgiving,
Don W3FPR

I strongly agree with Jim, K9YC on this.

One way and place to start,? power the transceiver from a battery such 
as a lawn tractor battery.? Then dump the main breaker to the house.? 
Make sure any UPS is also OFF.? Then turn off all of the individual 
breakers.? Check and note the level on the receiver with one antenna and 
normal settings on the receiver.? Don't change antennas or receiver 
settings. ? Just note the noise level. ?? Turn the main breaker ON.? Go 
note the noise level.? There should not be any change.?? Now, one 
breaker at at time, turn it on and note the noise level for each one.? 
The next breaker on and note the noise level.? And continue the 
process.? Now, if you see or observe a noise increase with a particular 
breaker on, that says something on that circuit is causing noise.? Find 
out what it is and take corrective action.?? It maybe necessary to 
replace something or to add a line filter at or to the offending item. 
Once you have completed the process with each breaker, and cleaned up 
your house, anything left is most likely outside of the house. ? That 
would be the neighbor's house or power company.? Good luck with those, 
although most cases, the power company will be available to clean up 
their system.......but you have to be willing to find the general 
location of the source of the noise first, be it on a pole, transformer, 
night light, and etc.?? As to the neighbors house......just buy some of 
their weed and be happy.?? {Grow lights?}

It is a time consuming process but well worth the time.? Seems we add 
things and the noise comes up a wee bit, then we add something else and 
the noise comes up a wee bit more, and etc.??? I just added some of 
those twinkling blinking Christmas lights.? My noise went up 
noticeably.? Guess I'll tolerate the noise until about Jan 2 or 3.? 
You'd be surprised at the number of things that cause noise that I've 
thrown in the trash.? Best place for most of the junk.

Does he blot out your K3S on all bands, or just if you if both are on 
the same band?

I have some avid DX'ers within 20 miles or less of my QTH, one runs a 4 
ele Steppr and legal limit.? He and I can be on the same band, both 
working FT-8 and neither knows the other is on the band.? Oh, I see his 
signal but certainly there is no receiver overload on my part.? As to 
him likely having a non-Elecraft radio.......can't say.

But perhaps the other fellow is causing some serious splatter. If so, 
that may be justification to contact one of the ARRL Volunteer 
Monitors.? If the issue is verified, that report goes to HQ, and they 
review the case.? And it may get turned over to the FCC.? At which point 
I am sure he would become very interested in what his equipment is 
doing.? No one likes to justify their operation to the FCC.

If you are having overload issues, perhaps you need to review your 
receiver configuration, set-up, and operating practice.?? Or just go to 
another band.

working FT-8 and neither knows the other is on the band.? Oh, I see his 
signal but certainly there is no receiver overload on my part.? As to 
him likely having a non-Elecraft radio.......can't say.

But perhaps the other fellow is causing some serious splatter. If so, 
that may be justification to contact one of the ARRL Volunteer 
Monitors.? If the issue is verified, that report goes to HQ, and they 
review the case.? And it may get turned over to the FCC.? At which point 
I am sure he would become very interested in what his equipment is 
doing.? No one likes to justify their operation to the FCC.

If you are having overload issues, perhaps you need to review your 
receiver configuration, set-up, and operating practice.?? Or just go to 
another band.

In my experience, the single most important factor in reducing RFI 
problems is to prevent RF from flowing back into the station via common 
mode current on the feedline. This is easiest to do with balanced 
antennas. If they are coax-fed, then you need the appropriate choke at 
the feedpoint. And if the coax does not run perpendicular to the 
antenna, then a choke will probably be required at the entry to the 
shack as well.

Balanced antennas fed with balanced line like window line or open wire 
line work best with true balanced antenna tuners. The common practice of 
feeding a balanced line running a high SWR via an unbalanced tuner and a 
balun is less efficient both from the standpoint of power loss (the 
balun gets hot) and choking efficiency (the common mode current gets 
through).

An inherently unbalanced antenna, like an OCF dipole, also requires 
choking, but the demands on the choke(s) are higher.

RFI problems will vary according to the lengths of the feedlines and the 
band in use. A system that is clean on one band may be dirty on others 
if common mode currents aren't suppressed.

The time to apply ferrites is AFTER you have done the best possible job 
of reducing common mode currents, and after all your equipment is bonded 
together. I found that bonding my metal operating desk to the system helped.

Hi Vic,

I'm quoting only the lead sentence for context, but ALL of this post is 
absolutely right! The only thing I would add is that proper bonding in 
the shack and in the home is also critical.

BTW -- you and I have been working each other since about 1957!

I wish that Elecraft would make available the board layout, parts lists, 
etc that would allow somebody to replicate these boards. Even if nobody 
wanted to produce them commercially, there are a raft of prototype 
houses that would build a one-off version at a reasonable price ... at 
least "reasonable" compared with the alternative of having a mostly 
useless rig if you are a contester.

I am trying to use cross band SO2V with my new K4D.

For instance, I have my VFO A set to the 20m band, and the VFO B set to 
the 40m band.

A/B (or B/A) does not work any more as the appropriate band filters are 
not selected.

(Split not working is somewhat understandable, but A/B not working is a 
bug in my mind.)

Hello,

I have a KPA500, (working fine), however, at one, and only one, fan 
speed there is a resonant vibration coming out of the amp.  It is one 
speed above just starting...

It is also clearly a resonance vibration, not a PS hum.  It is also only 
present when the fan goes up one speed from whatever is the first speed.

Has anyone else experienced this, and if so, what was the fix?

Message-ID: <006f01d7e302$a3acce90$eb066bb0$@nbnet.nb.ca>

Just bought a K1..an oldie but a goodie, I guess.

NB board and 2 bands board (20/40) No tuner.

 

So, just playing around, getting familiarized with this new-to-me little rig
before transmitting or hooking it up to a real antenna and I notice:

 

on 20m:  it tunes from 13.974MHz - 14.063MHz

 

and on it tunes from 40m from 6.980MHz-7.068MHz

 

When I transmit on a nearby rig or compare frequencies to DX cluster spots,
just using a chunk of wire for an antenna, and listen for the various
stations it looks like the VFO is reading pretty much bang on. 

 

So, is this a matter of incorrect components installed or a poor alignment
or the (re)seller messing with the "CAL" in the menu or ??

 

I don't really want to mess with it too much, but I am missing 20-25kHz of
usable bandwidth on each band. (seems like I have about 88kHz of tuning
range, but 20-26kHz of it is below the bands---oof !)

 

Ideas?

 

TIA !

 Mine that I built around 20 years ago tunes:
40m 6999.9 - 7088.820m 13994.2 - 14083.4

See page 28 of the manual.? The tuning range depends on the value of C2.? The range can be further adjusted by the number and spacing of turns on L1.
It would be a good idea to go through a complete alignment on the rig, especially to ensure RX offset agrees with with TX/displayed freq (C13, page 47).

I think what you are seeing is probably typical. I have a K1-4 that tunes down to 6988 and 13982 on 40 and 20 respectively. My tuning range is a little wider at 93 kHz. 

The Owner?s Manual has a detailed section on VFO alignment. If you didn?t get a manual with the radio you can probably download one from Elecraft. 

Good luck and have fun with this little beauty.

Hmmm ... Elecraft has a very significant investment in those data [often 
called Intellectual Property].? Can't really see them just giving it 
away.? Likewise computer codes.? I'm not at all surprised that they're

Mike,

The K1 must tune a bit below the low end of each band.? That is to 
compensate for the crystals on the band board not being precision 
crystals - so your K1 is behaving as normal.

You CAN tweak it by a small amount on ONE band (the 2nd band will change 
too).

In your case, I would choose 40 meters since it is only low by 20 kHz 
while 20 meters is low by 26 kHz.
You can do this in receive by looking at the frequency display because 
you have already confirmed it is showing the correct frequency.

Tune the VFO to the low end of 40 meters and then spread (or compress) 
the turns of L1 a little at a time until the display shows about 
6995kHz, then check 20 meters to make sure it is a bit below the band 
edge too.
That is the best compromise that you can do without losing a bit of the 
bottom edge of the band.

73,
Don W3FPR

Thank you very much Don !

This is exactly the type of FB information I was looking for.

I rec'd a few emails telling me to calibrate it, however the VFO reads right smack dab on perfect, so I didn't
wish to mess with it by redoing something that may not help.

I'll probably just leave it (at least for now), but your info is very much appreciated and I'll save it for a rainy day perhaps.  
The only time I would ever make a QSO above 7068 or 14063 would be in a contest, and this would not be the rig I'd be contesting with, hi

I have a ton of other rigs (some Elecrafts too....KX3, KX2(on order) and a K3) and some Japanese rigs too.....All are much better suited to contesting.

This lil' guy will see light duty as a Motorcycle mobile (portable, really) rig for Parks or Islands on the air and the occasional Wednesday "CWT" (an activity event like a contest).  I like its simplicity and very small size.  Good for the Harley.

Thanks again Don and all.

What a great bunch !

Maybe see some of you (all of a sudden!) in CQWW CW this weekend.  I'll be 15m single band.

Mike,

The K1 must tune a bit below the low end of each band.  That is to 
compensate for the crystals on the band board not being precision 
crystals - so your K1 is behaving as normal.

You CAN tweak it by a small amount on ONE band (the 2nd band will change 
too).

In your case, I would choose 40 meters since it is only low by 20 kHz 
while 20 meters is low by 26 kHz.
You can do this in receive by looking at the frequency display because 
you have already confirmed it is showing the correct frequency.

Tune the VFO to the low end of 40 meters and then spread (or compress) 
the turns of L1 a little at a time until the display shows about 
6995kHz, then check 20 meters to make sure it is a bit below the band 
edge too.
That is the best compromise that you can do without losing a bit of the 
bottom edge of the band.

Julia,

That is designed in to prevent the audio front end from being damaged by 
a high audio level.
For those who have read my document on setting the audio levels, I was 
careful to state that one should start with each audio level (computer 
and KX3) to mid-range for a starting point and adjust from there a bit 
at a time.

More to the point, the reason Elecraft has stopped building certain 
products is that key components are no longer available.

Oh, I get that, I just don't understand why the radio doesn't more clearly
indicate what's happening, with something like flashing full bars or an
error code ("HI MIC"?). As it stands, an operator can't tell "input is too
low to trigger ALC at all" from "input is so high the radio is ignoring it
entirely".

Yes indeed.? I wonder what the availability and useful life of the 6L6 
or 807 types were?? They were ubiquitous in 1953 when I began, and they 
continued well into the 70's before power semiconductors came on the 
scene.? Excluding the NE555 which seems to have an infinite lifetime, if 
a semiconductor component stays alive in the supply chain for 5 years, 
it's a long-hauler. ?

I can see that for the radios themselves, but something like an IO board
seems less likely to have competitively clever design tricks in it.

I can also see keeping the designs of even simple expansion boards secret
while the radio is actively being sold, since cheaper clones would threaten
the profit needed to recoup the R&D on the boards, plus the clones might
use inferior parts.

But it does seem like, at this point, releasing a schematic and board
design would be helpful to users with less downside to Elecraft.

...also, I don't think there *would* be anything wrong with sharing the
factual details of a dispute if you've made a good faith effort to resolve
it privately and gotten nowhere?

"Don't say anything disparaging about anyone else in the group" can end up
papering over a *ton* of (technical or social) harm being done and
preventing it from being resolved.

Thanks for the comments and ideas for a K2 battery charger. This would simply be to charge the battery when away from home, so I don?t really care about RF noise.

I can see that for the radios themselves, but something like an IO board
seems less likely to have competitively clever design tricks in it.

I can also see keeping the designs of even simple expansion boards secret
while the radio is actively being sold, since cheaper clones would threaten
the profit needed to recoup the R&D on the boards, plus the clones might
use inferior parts.

But it does seem like, at this point, releasing a schematic and board
design would be helpful to users with less downside to Elecraft.

Both of those reasons are bogus in my opinion.

For the first, a digital interface board is way down the list of what 
would be actual intellectual property.? There is no software or special 
circuitry such as an LPGA or similar) involved at all.

For the second, I sincerely doubt that Elecraft used some special 
capacitor or some tight tolerance part or an obsolete digital chip for a 
simple digital interface.? They simply wouldn't have needed to.? Most of 
the products that Elecraft has discontinued have nothing to do with 
unavailable parts ... other than delays due to supply chain issues.?? 
They discontinued those products because they had limited human 
resources to maintain that breadth of product line.

I'd bet that it would be possible to reverse engineer the KIO3 boards, 
which based upon the number of posts here to the reflector are fairly 
high on the list of chance for failure ... it would just be far easier 
to have the parts list and board artwork to work with.? Elecraft has 
nothing to lose (and a lot to gain in terms of good will) by making 
those things available for extending the life of products they once 
promised we could always count on them for.

Would you try to replicate that board from that schematic without having 
access to the artwork for the board??? No frigging way.? It has to fit 
into a fairly small space.

Because it?s old is no guarantee it?s gone. I have numerous through hole semiconductors dating back to early ?90s designs that are still available. Making the blanket statement that it can?t be produced because components must have EOL is meaningless. If that parts had significant usage, they very likely still exist. Even if not, small qtys, say <50 can be found from brokers.

They were ubiquitous in 1953 when I began, and they continued well into the 70's before power semiconductors came on the scene.  Excluding the NE555 which seems to have an infinite lifetime, if a semiconductor component stays alive in the supply chain for 5 years, it's a long-hauler.

Message-ID: <3f83ff08-30b4-cdd3-6b68-d24769caf9b8@bates.edu>

The receive screen on my KX3 Utility/Terminal shows fewer characters 
than on the text screen on my PX3, also different from the text screen 
on the KX3.

I can decode CW better in my head than the KX3, PX3, or KX3Utility!

Does the KX3 Utility terminal decode digital signals at all?? I've never 
gotten it to work.

Setup is simple KX3, PX3 and Signalink.

The KX3 Utility doesn't *decode* digital signals, it just reads out the
characters the KX3 has decoded, just like the PX3 does. I don't think you
can have both the PX3 and a PC app showing decoded text at the same time;
the manual says it's unsupported, and from the programmer's reference it
seems technically possible but tricky. (There's a command to read received
characters from the KX3, and both recipients would need to watch for
responses to that command *even when they haven't asked for any*, or else
they'll miss text sent in response to the other recipient's command.)

Good observation, which I should have known.? Only the KX3 decodes. The 
KX3 Utility displays only part of what is on the KX3 text display and 
must be losing something along the way.? The PX3 seems to display what 
is on the KX3 text display, but often adds a lot of characters.? Has 
anybody had success using the KX3 Utility Terminal?? Fred Cady 
recommends it.

My experience with the K3 may have some application here. When 
using the K3 to decode CW/RTTY, the decoded text can be 
displayed on the K3, on the P3, or have it sent to a computer. 
If you try to display it on the P3 and send it to the computer, 
both locations drop characters. If you want the computer to get 
the complete decode, turn off the display on the P3.

Victor makes a good point here.? One thing to examine and one point 
often overlooked and largely not understood by hams and manufactures has 
to do with baluns and common mode chokes.? All are not created equal, 
regardless of what the glossy advertising may say.?? Baluns in tuners 
are largely incorrect designs and have been for years.

I recall that Jim, K9YC was asked to test a group of baluns of a certain 
company, in preparation for use at an off-shore DX station.? In summary, 
his results indicated they were barely, if at all, a balun. ? Otherwise, 
expensive junk!

Personally, I have all of Jim's works in a binder.? I also subscribe to 
the work of Tom, W8JI and that of Rick, DJ0IP.? What they say and write 
is fact!? What is advertised is more "old ham lore" and they want you to 
drink the "kool-aid".

What ever your choice of antenna and feed line orientation is your 
choice.? Likewise the correct balun and common mode choke. The latter 
seems to create more incorrect information and results than favorable 
ones.?? Follow the work of Jim, K9YC, Tom, W8JI and Rick, DJ0IP and 
build your own.? Do it correctly and they are easy and a whole lot less 
expensive, saving one $100's of dollars and getting much better 
results.?? If there was a good commercial balun available, I'd recommend 
it.? But....sorry to say.....I haven't found one.

In my experience, the single most important factor in reducing RFI
problems is to prevent RF from flowing back into the station via common
mode current on the feedline. This is easiest to do with balanced
antennas. If they are coax-fed, then you need the appropriate choke at
the feedpoint. And if the coax does not run perpendicular to the
antenna, then a choke will probably be required at the entry to the
shack as well.

Balanced antennas fed with balanced line like window line or open wire
line work best with true balanced antenna tuners. The common practice of
feeding a balanced line running a high SWR via an unbalanced tuner and a
balun is less efficient both from the standpoint of power loss (the
balun gets hot) and choking efficiency (the common mode current gets
through).

An inherently unbalanced antenna, like an OCF dipole, also requires
choking, but the demands on the choke(s) are higher.

RFI problems will vary according to the lengths of the feedlines and the
band in use. A system that is clean on one band may be dirty on others
if common mode currents aren't suppressed.

The time to apply ferrites is AFTER you have done the best possible job
of reducing common mode currents, and after all your equipment is bonded
together. I found that bonding my metal operating desk to the system helped.

In reading this, it brings a point of history to mind.? If the equipment 
was damaged by a thunderstorm or lightning, my personal experience, is 
that one's homeowner's insurance should pay replacement cost, less the 
deductible.?? I'm no insurance specialist and I'm sure policies are 
different in this regard. However, what I learned is that an "electrical 
surge" which damaged equipment will be covered at the depreciated value 
of the equipment.? Yet, lightning damage which damaged equipment will be 
paid at replacement value.?? There is a BIG DIFFERENCE!

Yes, one has to prove lightning damage, it can be done, but is it worth 
getting a new radio vs. having to scrounge around to find parts and 
repair an existing radio.??? I know, in one instance, I had some $12K in 
damage from lightning.?? I had to pay the $1000 deductible? but 
everything was replaced NEW!??? TV's, surround sound systems, satellite 
receivers, telephones, microwave, ham radios, ham amplifiers,? garage 
door openers, and such.

Persistence pays!

LOL.? I bet you don't even know if the board is multilayer or not. I 
don't, and I'm not about to pull it out of the rig just to find out.

I had a KIO3 board go bad in the past and was lucky enough to be able to 
replace it then.? Pretty certain I'm screwed if it happens again.

It's called component level repair!

Back in the thermionic emission days it was common. Today you need 
magnification and sometimes a hot-air solder station but it can still be 
done.

If one has the physical board in hand AND the schematic AND it's not an 
exotic or high speed board, it shouldn't be too hard.  I would hand 
enter the schematic into KiCAD then hand-place
the parts.  Some things need to be placed precisely - mounting holes, 
others not so much.

KiCAD will keep you honest - although it doesn't have auto routing, it 
makes it easy to
verify that everything is connected to what it must be connected to.

If the layout doesn't work out 2-layer, then I would go four-layer.

I have the rework equipment in my RF lab to fix these boards and have done so on many occasions (there are basically only two parts that can go bad on the USB side... the ESD diode pack and the MAX-USB chip, both of which are surface mount packs that can easily be removed).  If you have bad KIO3B boards, please sell them to those of us that can repair them and keep them in stock for future needs.

It's definitely a multi-layer board, but the thing is so easily repaired, this is not necessary.

If one has the physical board in hand AND the schematic AND it's not an exotic or high speed board, it shouldn't be too hard.  I would hand enter the schematic into KiCAD then hand-place the parts.  Some things need to be placed precisely - mounting holes, others not so much.

KiCAD will keep you honest - although it doesn't have auto routing, it makes it easy to verify that everything is connected to what it must be connected to.

If the layout doesn't work out 2-layer, then I would go four-layer.

My KI03 board failed in 2020 and I was lucky to get it repaired by 
Elecraft (though it took months due to Covus issues).

I blew up a ferrite cube and IC so decided to have them do the repair 
since the IC leads were high density and I didn't trust being able to 
desolder without damage to the board.  Highly suspect board is multi-layer.

Without use of the KI03 board my K3 would be useless.  Hope it doesn't 
fail again.  Cause?? as we get no lightening locally.

LOL.? I bet you don't even know if the board is multilayer or not. I
don't, and I'm not about to pull it out of the rig just to find out.

I had a KIO3 board go bad in the past and was lucky enough to be able to
replace it then.? Pretty certain I'm screwed if it happens again.

I think that's an excellent offer.? In the absence of Elecraft 
supporting these older boards (as I stated in my first post, when I 
asked Elecraft to repair my KIO3 they declined), it would be great if we 
could compile a small database of people like yourself willing and able 
to do proper repair ... for a reasonable fee, of course.

If somebody was willing to do this on a regular basis, I suspect that 
many of us would be willing to simply donate older/excess boards.? I 
have a couple that I would.

Message-ID: <c01296f3-9172-241f-c53a-4636a0847b5e@acsalaska.net>

I primarily work eme so band noise is a prime enemy of weak signals.

I was reading the comments about combating mic noise and wondered if 
adding some ferrite beads to my 6m coax at the shack would have any 
effect on received broad-band noise.  I definitely see the noise peak in 
one direction of the antenna S5/S7 vs S2 at 180-degrees azimuth 
rotation, and it also drops with about 13 degrees of antenna elevation.

My 6m LFA antenna use ferrite bead baluns.  Transmission coax runs 
40-foot vertical and 50-foot horizontal on the ground.  Rx comes from a 
remote preamp connected thru a TR relay with output thru LMR-240 coax to 
the Rx antenna port of the K3.

If it does, something is very wrong in your shack, like bonding. What 
DOES matter is having effective common mode chokes at the antenna's 
feedpoint. See my recommendations at k9yc.com/publish.htm

I don't see how a common mode choke would help in that situation. If the 
noise changes that dramatically depending upon where you have the 
antenna pointed, that strongly suggests that the noise is being received 
by the antenna and is not riding on the shield of the coax.? If it is 
received by the antenna it is differential in nature and a common mode 
choke won't do anything.

It sounds like you are being plagued by either a local noise source, or 
the atmospheric noise is much stronger in one direction.? In my case, 
the background noise during the middle of the day is always stronger 
east versus west even though there isn't any significant housing or 
businesses within 200 miles east of me.

Can you say "planned obsolescence?"

There are lots of good and bad reasons for this, so I am not dissing 
Elecraft in any way.? One of the good reasons is the difficulty in in 
maintaining parts and repeating production of rarely ordered minor 
daughter boards,? and then there is the incentive to retire that old rig 
and sell/buy a new one!?? Again, I am not casting aspersions in any 
direction.? A small manufacturing outfit can only do so much for so long 
before it must move on.?? Ten-Tec used to stock as many parts for as 
many old, retired models as it could. But then, ham radio was more of a 
hobby to it than a main line of business, like its tool and die and 
metal fabrication line.? TT owners used to call the Service Dept to 
discover what and how to fix their aging radios, and kept them going and 
going seemingly forever.? No wonder it could not sell its newer models 
to older customers!?? It is a balancing act - how long can Elecraft 
afford to maintain older models, while moving ahead with newer 
products?? Not so easy I think.?? K8JHR

I?ve only repaired two of these boards, but it was way more than two parts.  The ones I fixed had the hub, voltage regulator, switches, and one other device get toasted.  All surface mount, so easy fix once the dead parts were identified.  Cheap too, I think it was no more than $10 per board parts cost.

Returning to the original subject ... I've found:

1.? Power, by itself, is usually one of the lesser factors in such cases 
of interference.? It does come into play in #3/#4 below

2.? Audio input level is a big contributor when it's set too high and 
you're saturating the PA.

3.? Phase noise may be the largest contributor to the interference that 
plagues many.? There was a period, around the beginning of the 21st 
Century, when some of the most popular transceivers had a fairly high 
level of transmitted phase noise.? It was commonly high in the same 
transceivers that exhibited heavy key clicks.

4.? Strong enough phase noise into a receiver can generate it's own 
phase noise internally.? My TS-850 suffered from this problem when KF6T 
was on about 2.5 km from me.? It wiped out the entire band, while on my 
K2, Jack's phase noise was only about 5 to 7 kHz wide.? Still too much, 
but nothing like the TS-850 appeared to indicate.

5.? Saturating the core of an RF transformer/balun is almost as loud a 
noise as dropping your rifle while in formation. ?

I haven't heard from Elecraft yet, I am pretty sure I will need a KIO3

While it is unlikely to make any difference, if you can source these
ferrite sleeves in the USA they are excellent value and perhaps worth a
try. A pack of 5 cost about $1.50 plus shipping and tax (?1.15 + tax in the
UK). Two packs (10 sleeves) should make an effective choke for 6m and will
slip over RG213 size coax.

My own measurements of them with a VNA look OK with 10 used on 6m and 4m, 5
are suitable for 2m.

After working on some (not all) of the K3(s) boards myself, I suspect there will be a range of talents on different boards and equipment.  I've worked on the KIO3(B) boards, the KPA500 daughter card and power supply, and the KPA1500 (all) so far with success.  Know my way around them very well... and know the symptoms and fixes.

I think that's an excellent offer.  In the absence of Elecraft supporting these older boards (as I stated in my first post, when I asked Elecraft to repair my KIO3 they declined), it would be great if we could compile a small database of people like yourself willing and able to do proper repair ... for a reasonable fee, of course.

If somebody was willing to do this on a regular basis, I suspect that many of us would be willing to simply donate older/excess boards.  I have a couple that I would.

The number of parts zapped by a lightning strike is impossible to determine
in advance.  The more ground paths you have (USB cables, Aux cables, audio
cables, etc.) the higher the probability of higher part mortality count.
However, in every when only the USB cable was connected, I just had to
replace the TUSB2036 and the USBLC6-2 ESD protection packs.

Your mileage may vary... lightning of course.

I?ve only repaired two of these boards, but it was way more than two parts.
The ones I fixed had the hub, voltage regulator, switches, and one other
device get toasted.  All surface mount, so easy fix once the dead parts were
identified.  Cheap too, I think it was no more than $10 per board parts
cost.

The two boards I saw had an event on the USB 5V line, not the data lines.  Almost everything connected to the USB 5V line was toasted.  So the failure modes would be different depending on the actual event.  One thing is for sure:  be sure everything in the shack is bonded so that you don?t get a ground bounce.  That is sure to take out lots of stuff.

The number of parts zapped by a lightning strike is impossible to determine
in advance.  The more ground paths you have (USB cables, Aux cables, audio
cables, etc.) the higher the probability of higher part mortality count.
However, in every when only the USB cable was connected, I just had to
replace the TUSB2036 and the USBLC6-2 ESD protection packs.

Your mileage may vary... lightning of course.

I?ve only repaired two of these boards, but it was way more than two parts.
The ones I fixed had the hub, voltage regulator, switches, and one other
device get toasted.  All surface mount, so easy fix once the dead parts were
identified.  Cheap too, I think it was no more than $10 per board parts
cost.

Respectfully adding to Pete's response: "sidetone level on line out" to 
me means the amount of audio on the line out output while you are 
transmitting, to "monitor" your own transmissions.

If this is what you are after, there is ab obscure description in the 
release notes of the K3 5.88 firmware description:

TX LINE OUT (MONITOR) LEVEL NOW ADJUSTABLE:
In CONFIG:LIN OUT menu entry, tap '2'  (REV switch) to set the "T=" 
level (TX monitor). Tap '2' again to return to the RX LINE OUT setting.

Hope this helps,

Message-ID: <24a986b3-4d1e-ec6f-7cb4-3869bfc3d338@acsalaska.net>

OK, kind of what I was thinking.  So either go on search for noise 
source or try reducing the noise at the receiver.  K3 NB does not 
improve SNR on 6m.

On HF noise varies: 80m its S7 from an inverted-V; on 20m its S3 from a 
yagi (both have baluns).

6m noise at S5-S7 is the most troublesome because I do weak-signal 
operating (eme, ms, FT8). InnovAntenna 6m baluns are many ferrite beads 
in series.  6m yagis are LFA7 from InnovAntenna (UK).

Shack is grounded via No. 8 wire to ground post adjacent to shack. 
Aluminum plate coax thru-wall panel is grounded by it, as well.

ED-KL7UW
-----------------
If it does, something is very wrong in your shack, like bonding. What
DOES matter is having effective common mode chokes at the antenna's
feedpoint. See my recommendations at k9yc.com/publish.htm

73, Jim K9YC
------------------
I don't see how a common mode choke would help in that situation. If the
noise changes that dramatically depending upon where you have the
antenna pointed, that strongly suggests that the noise is being received
by the antenna and is not riding on the shield of the coax.? If it is
received by the antenna it is differential in nature and a common mode
choke won't do anything.

It sounds like you are being plagued by either a local noise source, or
the atmospheric noise is much stronger in one direction.? In my case,
the background noise during the middle of the day is always stronger
east versus west even though there isn't any significant housing or
businesses within 200 miles east of me.

The K3 NB has lots of tweaks. Depending on the modes you use, it might 
help in some situations.

Of course -- noise sources vary widely in their spectral content, and 
how much we hear will depend on what they are using for TX antennas and 
how those TX antennas are coupled to the noise sources. Likewise, how we 
hear them will depend on our antennas -- their location, directivity, 
and whether they are well choked at the feedpoint.

Is that S5-S7 on a well calibrated S-meter?  That's HUGE.

You need to STUDY N0AX's ARRL book on Grounding and Bonding, to which I 
contributed, and/or this slide deck pdf.
http://k9yc.com/GroundingAndAudio.pdf

Also these to chase down and kill the noise sources. The first is text, 
written for National Contest Journal, the second is a slide deck.

*** I have been fairly indulgent on tool purchases recently.  I have 
retired
my flea market binocular microscope in favor of a digital
camera/microscope with an 8 inch display.  No more craning my neck to 
get to *exactly*
the right spot to see in that little eyepiece.

without the Metcal
price.  This sucker heats up in about 10 seconds.

I have one on order. Not sure if they have a larger amount then what was 
pre-ordered.

Subject: [Elecraft] K2 No SSB output power with new SSB board fitted.
Message-ID: <CADnt6w0c2LQVxFi23pYqGuCGHEDm9Vu+4qyyTa8iS_EVLs-u1g@mail.gmail.com>

Everything setup to the point of ?Fine carrier Balance Adjustment. But no
RF output. The SSBA BAL adjustment worked fine so there must be a low level
SSB signal to be fed back to the Rx. Current jumps from 222mA to 398mA on
activating PTT. No increase with audio input, no S meter indication or
indication in wattmeter.



New SSB board swapped out with known working one from another rig. The
newly built board works fine in the other rig. Known good board does not
work in newly built rig. Stating the obvious the SSB boards are fine there
is something up with the new rig. CW works ok with full output power.





Mike is Elecraft MH4.

Continuity of AF pin1 confirmed up to pin5 of J11.

W2 and W3 removed, also C167.

Message-ID: <CABs+SNC7bTejORpc41Q8Hgb1D6A+0dKi6A99EDo0Fqr6WpDdqA@mail.gmail.com>

About 8 hours into CQWW CW, one of my P3's bandscope function stopped
working. I checked the cables. I powered the unit off. When it came on, it
worked for a few seconds. The outboard monitor worked for a few seconds.
Then it stopped working. I did this a few times with the exact same
results. I never turned it or the radio off after the contest. This
morning  before swapping P3s to make sure it was a P3 issue, I turned the
P3 off and when I turned it back on after just a few seconds, it worked
perfectly. I felt half blind during most of the contest, so I want to make
sure I don't run into this again. Any suggestions.

Mark,

I am guessing that bias voltage is being supplied from another route or 
that MH4 would not work. Some ops place the resistor on the mic 
configuration header as opposed to the mic connector itself. That may 
explain why it is working in the other rig.

Either way, sounds like you have things working. Enjoy!

Ken,

I have not experienced the difficulty
with my P3 that you encountered,
but the fact that both the P3 front
panel display and the external SVGA
display shut down indicates a problem
with data not being provided to either
display driver system OR there is a
thermal problem with one of the
onboard voltage regulators on the P3
Rear Panel I/O board.  The P3 has
both +5V and + 3.3V regulators with
crowbar over-voltage protection, and
both are fed from the +12V DC input
jack.  The P3 SVGA board has additional
voltage regulators supplying 1.2, 2.5, and
3.3V, and these are fed from the +5 V
regulated supply on the P3 Rear Panel I/O
board.

My suspicion is a thermal sensitivity
in the +5 V regulator or its crowbar
protection circuit.  However, I would
first check the +12V DC input connection
to the P3 and be sure that it is stable
at +12V over time.  If you supply that
voltage from the auxiliary +12V output
of a K3 or K3s, you should also check
that the problem doesn't stem from
a problem inside the transceiver.  My
recollection is that a modification
was required in the original K3 to
increase the available current at the
auxiliary +12V DC output to support
the SVGA option in the P3.

I am curious to know what you find.......

Ken an Mike
I did some Troubleshooting over the Years.
2 thing to help.

I understand that there is an App for the I-Phone that 
Lets you see a Heat/IR Pattern on the screen.
This should help SEE a Heated Part.
The 2nd is, get a Can of Component Cooler/
Freeze Spray to Shoot the Hot Part and see
The Problem recovers.
I wou;ld Clean All Cables, Sockets and Plugs
Power Supply Connections FIRST.

Hi Eric.

Can you be more specific about the mod that improved the KNB1? I know there were a few changes early on, but mine is from about 2010 so should have had all the official mods in the initial build. Other than the ?make the threshold higher than it already is? mod, is there something else?

I wish I could!  My vague memory is that Don Wilhelm pointed me to a couple
of mods.  A search of my emails didn't find any of Don's advice prior to
2017, and I think that is about 5 years short.

I suggest you google it, and check the Nabble archives.  The mods were
simple, changing a cap and perhaps a resistor value or something.

The K1 is a great little rig.  I built the 2- band version, and then the
4-band filter board, with all options.  It still works like a champ.
