It’s only anecdotal, but I was in a 6M QSO where we both were receiving each
other with 20dB+ signals. I adjusted CMP from 0 to 30 and the difference heard
by the other station was 6dB. It definitely works.

There's always something new...
Our clubs went to 100W this year, after being leaders in QRP for some years,
up to #2.
We wanted new hams and the SSB crowd to have more fun.
I operated CW with one of my two K3, which worked fine, as usual.
But I experienced something never seen before.
The filter has been spoken for.

Hi Wilson,
The K3 looks for "reverse power" coming back into the antenna jacks in receive
mode. This is possible if there's a nearby transmitter, typically when the
antennas are in each other's near field. On 40 m this could happen even at 100'.
If reverse power becomes excessive, the K3 will

I used my K3S on 6M extensively on FT-8 over the Field Day weekend. I
used WSJT-X with the Radio Mode set for Fake IT .
For the radio I have DATA MD set to DATA A. I think this is band
specific. There should be no difference in the set-up for 6M being the
same for 160M - 10M.

There is a good chance your battery came with, or should have, advice to
charge the battery every six months or less to keep it alive.

The surprising part is that tuning was disabled during the strong signal

OK, got a massive problem that just cropped up this evening that is far

After restarting the PC, suddenly I cannot communicate with the radio using

It is possible the parameters set in the computer after reboot don't match
those set in the program. Check the port and baud settings.
Generally xom port settings need to match for communication to occur.

I am pretty sure I know the answer. I was sleeping when you called earlier

I think we may be in the territory of the difference between a circuit

It's possible (and I'm guessing somehow likely), but darned if I know what
