Exactly what I thought. Been doing a lot of testing and found below 130 watts or so the problem goes away. Will order some clamp on ferrites and keep the power down. 73, Bill

Also just noticed the mode switches between USB, where I set it, to LSB and then back again. This is where the VFO display is. Weird.

please? What rig do you have and what options have you selected for
WSJT-X "Settings->Radio->RIg", "Settings->Radio->PTT Method",
"Settings->Radio->Mode", and "Settings->Radio->Split Operating"? What I see is the VFO A frequency in Commander goes to 00 during transmit then back to my selected frequency when the rig is toggled to receive.

If so, the tx freq will change as RIT gets removed for TX.... Looks like I am getting RF via the CAT cable into DxCommander. When transmitting the VFO frequency will drop to 00 then go back to the selected frequency when in receive. WSJT-X and the rig's frequency does not change. What mix clamp on ferrites should I use on the cable?
