I'll watch your signals a while later today.... turn A on .... there might be something with the A amplifier channel.... or your have a very unusual noise,... it might be a cold solder joint or something on the amplifier board on one of the ICs ... perhaps the A amplifier might be going into oscillation.   I'd think you'd have some crossover signal into the B channel if it was external...
Meantime, remember what Thomas said above... your station is working pretty darn good!

hi Mike channel A is  now on  .. still run into Manuel mode

I will sent you via PM  my url   for the controller ,,, you can play with it  if you have the time ?
maybe you see something
but I now what you will see   ( a wave into the noise   )  

greetings  Gert

 Hi Gert... sent you a quick PM reply with additional thoughts:
Click the below video to play... I've a suspicion this is something arcing...
the video shows the FFT for your A channel E amp, and the signal and FFT for B...
this thing has harmonics around 10-12 kHz throughout the bandpass, but does not show that much on H field, which makes me think it's an arc, electrical, of some type... see the PM....

Hope it's minor, but see if you can track it down...

Respect, and Cheers!
Mike
