Conditions this week were very poor, earlier at around 0830 signals on
80m were strong from North and South America but that didn't equate to
good inter-G propagation a couple of hours later.
Some stations struggled to hear each other with apparent high band
noise, this prompted a discussion on

Hello there
With no Antenna connected and all parameters the same for Main and Sub VFO, my sub receiver produces only about 50% audio compare to my main receiver.
This results that i have to set my sub audio knob to the 4 oclock position to recieve equal audio in left and main headphone..

Hi, since March last year my K2/100/KAT100 was working very good, but in last
December I was tuning an antenna when suddenly it shut down and I could not
repower it again. (I guess I was selecting the wrong antenna) After that, one
of the PA transistors was damaged and I replaced
Peter,
Before you go into any troubleshooting of the power control circuits,
try this ---
Since you have the PA transistors out already, go into TUNE and measure
the DC voltage at the solder pads for the base of Q7 and Q8. If it is
not close to 0.6 volts, replace Q11 and Q13. Those
Dear group,
Not sure if I'm doing something wrong here, but I set SQ MAIN=SUB POT. As I
understand it, with this setting the main receiver and sub receiver squelch
is now controlled by the RF/SQL SUB pot. Squelch works fine when using the
main receiver, and I can see the squelch setting on
BTW, I forgot to add that the squelch only seems to work in FM mode. Is this
the case? Also, when using the sub receiver in FM mode, even if I adjust
squelch to the maximum, it will not go to full quieting.
I'm confused now.

OK, nevermind... turns out that the sub receiver was not in FM mode, hence
the reason squelch wasn't being adjusted.
I've also read on the reflector that squelch is only applicable to FM modes.
I hope that squelch will also be incorporated into other modes as well.

The 1 switch on the number pad switches from vfo a to b.
Could the switch tone function be changed such that it gives an indication
of which vfo? i.e. low tone for A, and High for B?
This would be very helpful for setting splits.

Jens,
Either check the menu or easier yet, use K3 Utility to check the filters
that are enabled for transmit for each mode. You should only have the
2.7 kHz filter selected for transmit in CW and SSB modes.
You may add the 250 kHz filter for receive - but not for transmit.

No Paul, it is not the same.
What I was writing about is the possibility of sending CW while you are in
mode SSB. This function is working properly as long as you are not using

function (in split) is on

Dear group,
Someone please explain to me what's happening with my K3. I have both main
receiver and sub receiver linked. This way, I can tune the sub receiver
with the main VFO knob. However, there's something weird going on when I
cross some sort of band edge.
For example, if both VFO

filter knobs will also induce this motorboat noise when turned. Any
suggestions on how to fix?

receiver is on, and I'm tuning
We had a good turn-out for the SSB net today (1800Z) on 14.316 MHz, even
though most signals were down from what they have been in previous weeks.
Most stations were S5/6, but there were a few up to S9. There were also
some near the noise level, and there was also a lot of QSB. The surprise
James,
What rev of firmware are you using? I went through test on all of
them I could with the subreceiver, which I didn't install until 2.72
was current. I can't duplicate your results with 2.82. It may not be
a firmware-related issue (or issues).
In the first problem statement, it sounds
My K3 does this sort of unexpected leap to next band up/down at tuning
breaks with linked or unlinked main/sub. I assumed this was because I
had the general coverage filter in the main but not the sub. Firmware 2.82.
No 'zipper' noise here except that little bit at the bottom end of 6m.

Hi Matt,
The zipper or motorboat noise occurs when tuning around 4.9-5.5 MHz or
4900-5500 KHz. It is most noticeable when the sub receiver is turned on,
the sub volume is up, and tuning steps are set to fine. The noise ONLY
occurs when I turn a VFO knob or filter knob. If I do not touch any

James,
I, too, have noticed what I believe you are noticing. It seems to me
that the jumps in the tracking of VFO A and VFO B occur at the
transitions of the bandpass filters. It is as if when the bandpass
relays switch, the VFOs lose their synchronization. (Of course, I
could be wrong,
I had a great time with my K3 during the ARRL DX contest. I do SP and I was
trolling around with my filter width at 50Hz. Absolutely outstanding. The
auto spot is equally outstanding.
At 50Hz width it was quite clear that many stations call off frequency.
Using RIT, I could see that it was
Looks like I may not be sticking to my explanation after all. Try
this and see what you get:

This is more than likely due to dirty signals on the TX end. I was
using a QS1R connected to the K3 IF and measured the width of some of
the strong signals. Some were as wide as 2.6 kHz Not very good
for a CW signal. In this case there is just not much you can do.

It seems that soundcard based AFCW has become popular with some
contesters, for reasons which elude me. There is great opportunity to
transmit wide, distorted cw signals if things are poorly adjusted.

Hi Bill,
Tried your experiment, and my main VFO jumped to 5.069.029 while the sub VFO
stayed at 5.999.99. This was with both receivers linked.
Trying the experiment again, this time with both VFO's unlinked as you had
requested, when I tune to 5.999.999 on the main, the sub also goes to
The behavior you are describing is almost the same thing I
complained about a couple weeks ago. In my case I was trying
to sort out several signals calling me in a pileup, but it's
the same basic situation. Fast agc, even with the highest
threshold and slp=0, compressed them all into an
I saw the same thing with a huge fairly weak pileup on 20m's today. This
really needs to get fixed asap. It makes working a pileup almost
impossible.

Mike,
The K3 is virtually desense-proof, with a BDR of ~140 dB. But to take
advantage of this, you need a narrow crystal filter -- the closer to
the DSP bandwidth the better. This is exactly the situation that we had
in mind when we designed the 200-Hz 5-pole filter. For CW pileups, you

I do not recall which one I was using at the time. At least the 400hz.
Keep in mind these signals were all s7 and below, most well below.
I was fresh blood on 20m this morning and got spotted. It was an ugly
pileup. The adjacent qrm was not an issue.
When I
I think what they are seeing is this: Strong signals that fall slightly
outside the DSP's audio passband are still pumping the S-meter and the AGC
is desensing the receiver. The DSP is acting more like and audio filter than
an IF DSP. In other words, the DSP's audio bandpass is very steep but
Good Evening,
Conditions during the net this afternoon were challenging. QSB effected all
of the eastern stations, QRN was strong, and QRM from the many contesters was
rampant. I was running with AGC off at first until the pain level got too high
to handle. Key clicks were pretty bad from
Have to ditto whats been said, I have to run with AGC off, audio set about
3 o'clock and use the RF gain. That seems to work fairly well, I use the
400HZ filter most of the time. Not sure what the problem is but the audio
goes to pot in a hurry in a pile up. Sounds strange and no pure
I believe that I encountered this a couple of times while in VP5 last fall...
there wasn't a roar of stations, the radio just sort of sat there and 'hummed'.
I turned the radio off, then back on, rechecked all of the settings, and kept
going.

Try going into the Config and setting your AGC THR down to 003 and see if that
improves. I had mine too high at one time and it caused stronger stations to
distort.

I'll discuss this with Lyle, KK7P (our DSP engineer). I don't think
this has anything to do with desensing if a narrow filter is being
used. I can't imaging
