I honestly do not know. I have only listened in ssb band. I have listed up at
top or down in cq. I will try.

I believe that I am hearing raspy or slightly distorted audio on receive on
my K3. It has current mods. I have noticed the problem only on 15 meters.
The other band seem fine. Does anyone have any ideas or suggestions? Barney

Barney,
The most common cause for problems of that nature is RF feedback in the
shack. If you have another receiver, listen to the transmitted audio
while the K3 is connected to a dummy load. If there are no problems
with that configuration, take a serious look at your antenna system for
Why would rf feedback be causing an issue on receive?

Whoops, I did not catch that on the first reading. I concede and have
no easy answers. Even so, the SSB demodulation in the K3 is not band
dependent either, so a good look at your antenna system and
consideration for the reception of interfering signals from consumer
devices are prime
The only distortion I have seen is with the NB on which he said he
checked. Is this an early version of the radio? Maybe this is a case
of oxidation on the connectors. Only hearing it one band makes this a
very interesting problem.

I bought the radio used earlier in the year. I believe that it is sn in late
2000 but it was to factory in 2010 for upgrades. I listened on same antenna
with ic-765 and no issues. Are there and settings which are band dependent that
could be causing the problem?

I have run into the first problem with my K2 S/N 1422, which has the latest
firmware and mods. I built it back in 2000 and not had any problems with
it till a few weeks ago. It now has an intermittent problem of receiving
and transmitting a very raspy audio. It is not caused by AC magnetic
Ouch, that hurts. Don, will probably have a solution. Just wanted to get
to you ASAP with an idea.

Steve,
Based on your sharp whack cure, but yes, that does usually indicate a
solder problem (or something loose).
I would first check RFC15 on the bottom of the board - it is connected
to pin 16 of U4 - check it with an ohmeter, even if it is open, it will
measure 5 volts on both ends. Since
Steve,
Another cause of intermittent raspy audio during both transmit and receive
could be a dicey solder joint in the KSB2's crystal filter circuit. If one
of the bandwidth settings you have chosen for the variable bandwidth crystal
filter is 1.8 kHz or wider, try switching to this filter
Well, despite not thinking I'd have time to correct my K2 raspy audio
until after the holidays, I managed to squeeze in a little time early
this morning and here's what I discovered:
1) There is probably nothing wrong with the K2 or the KSB2 board, as
far as wiring is concerned.
2) Don
John,
You have substantiated that the problem was a BFO alignment problem.
I would strongly urge you to check the FL1 passband using Spectrogram just
to be certain you have the BFOs set correctly. It is easier to use than to
tell you how to do it. There are instructions for using Spectrogram in
for the listening
rig to hear.
Try it on the air before you get too deep into troubleshooting.
