Log4OM

Hello,

I have the following problem:

When I perform a QSO on 20 in USB, in log4Om the display of the mode field changes several times during the transmission (RTTY, FM, CW, etc.).

When I release the microphone the field displays USB.

For information, during the transmission the TX is in USB and the rest during the entire transmission.

The problem appears on the 20m band and beyond.

I don't have the problem on the 40m band.

Do you have an idea, advice, a solution to solve the problem

This sounds like stray RF in the shack

Add Ferrite to all leads and cables to pc and a common mode choke to your coax

Good idea.
I order ferrites from amazon.
It only remains to wait to verify the hypothesis.
have a good night.
