I have found now the circuit at the elecraft ftp server.

Found out also that there is a brocken pin at the PA board at jumper at P68A male connector. This brocken pin still remains in the according female connector. So lots of problems.

I don't know this module but Elecraft "keys" some connectors by removing a male pin and plugging the corresponding female pin.  Are you sure what you are seeing is not intended keying?

Andy,
yes indeed I had a closer look and it seems that the left pin on P68A is by factory. I compared pictures of the pa board at google and there it is the same depend on board revision.
