Jim,
thanks for help.
AGC off, RF-Gain full open, 40dB preamp and so strong signals...

Cheers,

Hello all,

 I have traces of a 3rd station just above 137700. Who is that?

Dear Hartmut, LF Group,
I think that is an intermod, probably in the IF or audio stages of your RX.
It seems to be 2x(G3AQC's frequency)-(RN6BN's frequency); you can see the
frequency shifts in the faint lower signal are the mirror image of those in
the upper signal from RN6BN. If you reduce the RF gain a little it will
probably dissapear.
Cheers, Jim Moritz
