[Elecraft] KPA1500 odd behavior

[Steve]

While operating in the ARRL June VHF test on 6m SSB, I noticed that the main 
LCD display lost half of its display After a few minutes of on and off 
transmission. Nothing would bring back the full screen. It would reappear after 
turning the amp off and then back on. It would then loose half screen again 
after a few minutes of transmitting. Any ideas?

Re: [Elecraft] K2 BFO CW alignment question

[Mark Petrovic]

Don, thank for the excellent guidance.  I'll begin the debug process.

By the way, I have eliminated spurious contact between the encoder board
and control board, as I debugged that some weeks ago:
https://www.mail-archive.com/elecraft@mailman.qth.net/msg219585.html.
There is now room between the boards such that the plastic packing material
you mention moves freely about without friction.  This spurious contact
possibility was one of the first things I checked today when the "c"
indicator would not light.

[Elecraft] Elecraft CW Net Report

[kevinr]

Good Evening,

   QSB was the order of the day.  I gave reports of S0 to S7 or S0 to 
S5.  There were some atmospheric quirks too.  Odd sounding whistles and 
some buzzing.  I was told of lots of lightning east of the Mississippi 
but I heard none of it.  I was expecting more storm noise on 40 meters 
but there I heard the same screeches and buzzing noises.  However, I was 
able to work more than a few of you.  The QSB just makes it more 
interesting.  I did get the coldest spot of the day award too.  I would 
gladly lose.  52 degrees a few days before summer is not normal, even 
for the Pacific Northwest.  Luckily the berry bushes don't mind.  The 
thimble berries are full of white blossoms and the salmon berries are 
full of green and a couple orange berries.  The huckleberry bushes are 
done getting pollinated by the bees but not berries as of yet.  The 
strawberries are almost done blooming too so they should have a decent 
yield in a few weeks time.  No black berries within close proximity.  
The bears, coyotes, and deer love eating those long before I have a chance.


The nets 

  On 14049.5 kHz at 2200z:

NO8V - John - MI

K6XK - Roy - IA

W8OV - Dave - TX


  On 7045 kHz z:

K6PJV - Dale - CA

W6JHB - Jim - CA

VE7JBT - John - BC


Until next week,

    Kevin.  KD5ONS

Re: [Elecraft] K2 BFO CW alignment question

[Don Wilhelm]

Mark,

Analyzing the switch matrix is an iterative process
The first thing to do is to determine which wrong responses are being 
sent, and for that you must refer to the schematic.  In your case of the 
REV button and the STP 60 display, the hold of the REV button is 
bringing up the PF1 display.
Check the TAP function of the same button (AGC) to see if it brings up 
the RIT announciator (I think it will).
If so, it means that the D1 and D2 lines are somehow being activated at 
the same time.
Your first check would be to see if there is continuity between pins 12 
and 13 of U2.  Also check for continuity to ground for both of those 
lines.  If you find U2 pins 12 and 13 shorted together, look for the 
reason - a solder splash making a bridge or a bit of wire lead stuck 
between the pins, look top and bottom of the board.

That is how the process goes - as I indicated, it is not 'nice'.

Hopefully those two buttons are the only ones involved.
At worst, it means removing the pushbuttons and replacing them with 
new.  If it comes to that, clip the leads on the switch side close to 
the switch body and remove the leads one at a time, then troubleshoot 
the board.

Re: [Elecraft] K2 BFO CW alignment question

[Don Wilhelm]

Mark,

OK on that.  Since you have the new encoder board, it could be touching 
the pins on the back of the Control Board which can cause all kinds of 
"strange happenings".
First step is to flush cut (diagonal cutters will not do the job) the 
pins on the encoder board (cut right down into the solder). Then flush 
cut the leads on the back of the Control Board where it can contact the 
encoder board.
As an added protection measure, put a piece of card stock (business card 
of part of a QSL card) between the encoder board and the Control Board - 
or better yet a flat piece of plastic, like that used in many shrink 
wrapped packages from the store.


Then see if the behavior settles down.
If it does not, you will have to find the problem in the Front Panel 
switch matrix (not an easy task).

Don, the soldering on RP1 is very clean, top (viewed from the side of the
board with a light and magnifying glass) and bottom.  RP1 is aligned
correctly, and I've verified that it is the correct part for this location.

Worth mentioning is that the rubber spacer that installs onto the
bottom-side of the board in the corner nearest pin 10 of RP1 is attached
with a small drop of super glue (the original adhesive on the rubber pad

Re: [Elecraft] Field Day rig experience

[Wayne Burdick]

The K3S has exceptionally low TX phase noise and high RMDR. Both are due to the 
new synth. The rest of the signal chain is also very clean. 

You have to get this right on both RX and TX to optimize for close-proximity, 
multi-transmitter operation (e.g. Field Day, DXpeditions, and big contest 
stations).

First attempt to put amp on 6m.  No problem with antennas our output but

half the screen disappears with "50MHZ and PWR" only showing.  Then screen
goes completely blank.  I have ferrite on everything between the power

Because I switch other things besides my amp.  For example:

Beverages disconnected from RX input during TX.
Parasitic TX array elements (active during RX, to ground during RX).
Detuning stub on TX antenna (during RX).

Most of these relays are slow (and cheap) open frame relays.

With a little practice, I can listen between words (not characters) using a
footswitch.

And I have NEVER burned up any TX relays in my amps.

Re: [Elecraft] K2 BFO CW alignment question

Mark,

That indicates you are not getting the right button response.
Check the Front Panel Board.  My immediate guess is that you have a 
soldering problem on RP1, or that RP1 is inserted backwards. That is one 
of the R-Paks that MUST be inserted in the proper orientation.  Look at 
the board silkscreen for the pin 1 location, and look for the dot at the 
end of the R-Pak - they must be aligned.


You could also have a solder splash somewhere on the FP board.

Re: [Elecraft] K2 BFO CW alignment question

[Mark Petrovic]

Don, thanks.

When I exit CAL FIL, and press and hold CW RV, I see "ST P 0.60" displayed
(with the B RIT and XIT annunciators on) whether in CW, USB or LSB mode.

Mark,

Get out of the CAL FIL menu and see if it does toggle the bar when in CW 
mode.  In SSB mode, it should toggle between LSB and USB.
If it works in SSB mode, but not in CW, you may have a display fault 
that is not showing the bar - that is a different problem.

Re: [Elecraft] Field Day rig experience

[Ian White]

>I think the LO phase noise should be pretty close.

Perhaps it *should* be... but some of the worst examples of wideband
transmitted noise are caused by additional amplitude noise in the TX
chain, or by poorly filtered DAC noise in SDR-based transceivers
[1]. These noise sources are additional to the LO noise, and are
present whenever the rig is in TX mode (even without modulation).

That unfounded *belief* that "the LO phase noise should be pretty
close" was precisely the reason why none of the designers paid any
attention to the excess transmitter noise. But the equipment reviews
were equally at fault for failing to draw attention to the problem.

Re: [Elecraft] K2 BFO CW alignment question

Thanks, Don.  In CAL FIL mode, holding CW RV does not toggle a bar over the
"c".  All my calibrations and tests have gone swimmingly til now.  Any
suggestions on where to start to troubleshoot this?  Is there another way
to verify if the toggle is being honored (could the over-bar LCD element be

Ken,

You clearly are not a Repeater Coordinator in Southern California.

Co-channel interference is pretty common.

Most repeaters do encode PL on the output side, and a decoder in your 
radio is extremely helpful.

That depends a lot on where you live. Around Chicago and around NorCal, 
two places where I've spent a lot of time on VHF/UHF, most 2M and 440 
MHz repeaters DO TX CTCSS tones.

Re: [Elecraft] P3: Left span limit changes

[Fred Jensen]

I got two replies, one off-list, that they can replicate this effect.  
Study of the manual did not answer the question ... or provide a fix ... 
but I'm acutely aware that words that someone writes and that are 
crystal clear to them may [and often are] not nearly that clear to me. [:-)


If there's a fix in the works from Elecraft:  My preference would be to 
maintain the CENTER setting when switching bands.  This does get a 
little complex as a result of the 4 possible choices in MENU-->FixMode 
... I run my P3 in FullSpan mode and that would be fairly simple -- if 
VFO-B is changed such that tapping A/B would put the cursor off-screen, 
just shift the screen an integral number of spans to get it on-screen.  
HalfSpan, Slide, and Static modes are more problematical.


In the meantime, I will live with the current behavior.

You noted your left edge is at:  14020.000 ... mine (with a span of 20) is
at: 14018.000.  That is the only difference, but again I experienced the

[Elecraft] K2 BFO CW alignment question

[Mark Petrovic]

I am performing the first alignment and test of the RF board of my K2 S/N
7809.  On page 66 of the manual, I'm instructed to read page 91 of the
operating instructions to get familiar with the CAL FIL settings.  Page 91
says to work through the CAL FIL examples on page 93, wherein we work
through setting the BFO frequencies.  One of the steps says to hold CW RV
to switch to CW Reverse.  When I press and hold CW RV, should I expect some
visual element to change to indicate that I am in this 'reverse' mode?  I
don't see any visual indication.  How do I know the press and hold of CW RV
was effective?

Thank you.

CW is 100% Amplitude Modulation of a carrier by a rectangular wave, so 
the transitions are rich in harmonics that are heard as clicks, and they 
WILL excite IM in a non-linear path.

Yes, it does! 


All I've ever seen from Rob is RX phase noise. Can you provide a link to 
TX phase noise?  The TX phase noise data I've published came from ARRL Labs.

[Elecraft] Firmware version question

[Bob DeHaney]

Thanks guys.  I had assumed checking availability meant going on line to see
if a newer version was available.  My K3 now has version 5.62.
