F.Y.I:

I ignored the problem the last weeks...but now it also occured, when
I switch on the transceiver.

I identify the relay RL1002 on the RF-Unit as the troublemaker.
When I pushed with the fingers to this relay, the receiving level
comes up.=20
The relay cover can not be removed for cleaning, so I resolder the=20
relay connections of the board. May be it is a not well done solder
point.
It was a terrible work to get the RF-Unit out of the housing.

But.....now it works. Will see how long :-)
