Re: SOLVED Re: [BITX20] Bitx40 low volume oscillation squeal

 

Graham,

I figured out the squeal issue on my board. I was working on getting rid of the PTT noise that is annoying me.

If you interchange the VOLUME control wires RED and BROWN then when the control is low or zero then

the audio stages become unstable.

Cheers
