The OP has a radio that works sometimes, he provided a little information, and I asked a few diagnostic questions. There is no point in sending the radio away to be fixed until the diagnostic questions are answered. It isn't remotely clear to me that the radio is broken at all. His description sounds more like a loose ground than anything else. The Europa (one piece, circa 1971) is a robust unit and usually works just fine, compared to some of the higher-end Becker radios. I have never had one that failed in the manner that the OP has described, leading me to believe that the radio is not broken but rather it is a loose wire.
