Hello Markus, Eddie, Paul,

Thanks for the feedback, for trying and for the results.
Very strange. Paul has excellent results (as usual) but no decode for Eddie. On 8270 Hz, the 'difference' is much less expressed. Does it have to do with local QRM only? Maybe...
Maybe Alex has detected something.

Pauls results are particularly interesting. 1+1 =3D 1 * 2 =3D 3 dB. Proves the theory :-)

The stacking would help to solve the problems it seems :-) A tool is needed...
