Conditions this week were mostly OK, although continental contest
stations occasionally caused problems.
The Blackpool Rally was well attended with several Elecrafters meeting
with Peter, G3UCA and Ian, G0VGS, who were present on an Elecraft stand
and the Sands Contest Group stand.
Paul, M1PAF,
After extensive experiments with tx audio settings in pursuit of perfect
audio for my purposes - dxing on 80m - I came to the conclusion that for my
voice with the HC-4, an offset of -0.07 with the 2.8 kHz filter was about
right.
It's not unusual for the 8-pole filters to have small
Love the LCD display. I wish Elecraft had gone that route.
However, if and when something goes wrong (even though it's assembled already)
there's no Don Wilhelm or Elecraft mailing list to back you up, and to me
that's worth the extra money.

Just curious - I notice that your setting for AGC PLS (agc pulse noise
reject) is Off. Did that make a significant difference in your case?
Bob, I haven't noticed a difference with AGC PLS on or off. I haven't played
with it much so it may or may not make a difference in different conditions.

resistance checks do not seem to check out for several points:
P2, U5, U4 are all okay

U6 - pin 8 is okay (about 75K),

It's not unusual for the 8-pole filters to have small offsets, which would
be particularly noticeable if on the bass side of the passband. I've heard
of up to 80 Hz (0.08) in some CW filters. Anything large than that,
indicates something else may be going on (like accidentally resetting the
Phil,
The most likely problem is that you have a solder bridge somewhere (or
perhaps several). Look at the amount of solder on your connections. If
it has more than a very small fillet, there is too much solder.
Actually with the plated through holes just enough solder to fill the
holes is
Mike,
Since the goal is to make the 2 filters agree with each other, I would
suggest using stereo input to Spectrogram - the main RX on the left
channel and the sub RX on the right. It should be visually apparent
when the two filter passbands are overlapping each other to the greatest
degree

I just got the new K3 assembled, and I'm really enjoying it. However, I
have an issue with the line in not working, and I wonder if anyone
else has seen this with a recently purchased K3.

working. I've read

That carrier on 14.31800mc is nuts loud in Minnesota. I tried to check
in but only one station heard me and repeated my callsign. Even the DSP
won't wipe that screaming carrier out.

Hi Jim,
That makes sense. I was thinking a bit and realized most computer
motherboards have a 14.318mc oscillator in them. Then as you said the

There was a discussion here recently about being able to listen to the
main receiver in both ears while listening to the subreceiver only in
the right ear, which to me makes a lot of sense for contesting
optimum spatial cognition using both ears to pick out weak callers on
the main run

I am wondering if the RF gain encoders are read exactly the same between
main and sub receivers.
There is a significant difference in RF gain when I move them both down
together. I can turn the sub Rx RF all the way down and still have
appreciable RF gain, about equivalent to Main at half gain,
This has been corrected in a subsequent version of the K3 Utility. We're
working now toward getting a new K3 Utility version onto the Elecraft web

The adventurous may try the following. These commands do not stick
through power cycles, and may not remain through mode changes or other
commands. In other words, the radio may revert back to normal operation
at any time :)

Check what port, if any it's been assigned, and use that port address in the K3

That's VERY slick! And certainly simpler than using an external mixer.
As you say, it goes away with a power cycle, and also when I turn the
SUB off then back on. So far it seems to survive most other changes
I've tried, though ... mode, band, filter, VFO, etc.

If you crank in an offset with the 8 pole filters be sure
you test it with BOTH USB and LSB. An offset that enhances
low frequency response in USB will reduce the LF response in
LSB (enhance high frequency response) and vice versa.

13

that to the holiday and very weak conditions. Discussions were on
YOU ARE RIGHT, Joe !! I did my trials on USB. On LSB, I can tell by
listening and re-adjusting that you are quite correct. It's back to

If I wanted to check for filter offsets in the 8 pole

Set the DSP bandwidth to 4.00 and the center frequency
to 1.50 (SSB) or 2.20
This is great Lyle. I hope it makes it into a release soon as a menu option.
