Re: LLA+ gain control


Another thing to try if not done already.

Run everything that is 12v from a car battery..see what happens..

If goes down then it’s something that can be a decent mains filter..

I assume you are running everything sdr / loop from a linear psu and not a smpsu??
It would be rather embarrassing to discover its your own psu causing the noise...

Sorry but never meet starting with may be light years ahead of me in all this, and I mistakenly think you have not tried above..if so sorry..
