Hi Willie, Yes the 9700 has that function but when I did that the problem didn’t happen. It does seem quite random and intermittent. I suspected it might have been rfi as when I moved the 432 MHz ant in the roof the problem seemed to go away. But i have seen it back again and I haven’t altered anything.
I suspect something to do with the usb as another has reply has suggested.

Then you’d at least know which side of the audio/RF divide to look at… 73, Willie N1JBJ > On Jan 30, 2024, at 7:25 AM, Nic Sears via wsjt-devel > <wsjt-devel@lists.sourceforge.net> wrote: > > Hi there, Nic G3YEG here. > > I have been using wsjt for quite a few years both ft8 (hf, vhf and uhf) and > q65-60b on 432 eme and have never consciously notice the power output of any > of my previous rigs varying during ft8 or q65 tx cycles. > > Recently I Started using a new laptop with much higher spec than old machine > and also changed over to rc3.
