Can anyone recommend the best menu setting for max discrimination among
many callers at same time?
Start with Config menu: AGC SLP= 005 and then experiment with
different values. The lower the value (down to 0), the louder the
stronger signals will be. If you go too low, you risk
I thought this was corrected in a previous firmware upgrade. This apparently
is not the case. Output power still varies in the SSB mode by as much as 50%.
This shows up on the K3 ALC display and the power output display. Roy Morris

I hope not - though it could explain a few things. Surely the radio needs to
be in TECH mode. Tuning up an ATU would reset all the calibrations
otherwise. My amplifier needs about 50W of drive and my transverter about
1mW.

Mark,
I am puzzled since you say it transmits on 40 meters, but does not
receive - and that it receives well on other bands.
There is precious little in the K2 that would create that situation.
What do you have set for 40 meters that is different from other bands?

Hi
I like to make a complete record of a qso.
With the line-out at the K3 connected to the sound card I can record the

A poor man's way of doing that would be to take a feed from the speaker
or headphone output. That will have both RX and TX parts. Just don't
play with the volume control during recording :-)

As long as you use a good socket, there should be no adverse effects -
all the signals operate near DC or very low frequencies. Long term
there is always more of a chance for oxidation between the chip leads
and the socket than with a properly soldered-in chip, so you may want to

I agree that the K3 can easily be made to transmit excellent audio,
and I've been getting glowing reports on mine. I have a question.
Exactly where in the signal chain is TXEQ with respect to Line In,
Mic In, Comp/Lim, and the sensing for VOX? The absolute best place
for TXEQ is
MIC|LINE|DVR are summed, The result is sent to the VOX detector as well
as to the Tx Audio filter, which includes the TxEQ.
If the VOX detector were driven after the filtering, there would be
delay. This way, the filter delay acts to improve VOX attack time.
Tx EQ is a global control at

Yes, but it also prevents the TXEQ filter from removing LF trash
(breathe pops, mic handling noise) that false triggers the VOX. And
I'm having that problem. For the same reason,
Compression is after the filtering. It is feed-forward.
VOX is before the filtering.
Tx EQ is inseparable from the rest of the Tx audio filtering/shaping.

Wayne,
The TX gain constant is only there to compensate for small per-band
gain variation within the K3's transmitter. If you've done the power
calibration, then you can set PWR and be fairly close to the target
level on each band. Thus the MCU won't have to adjust power very much
