Dear members, after more than a decade mothballed, the reactivation of my former properly runnig Lincoln failed. There is no frequency readout and no answer to the PTT-Switch. Without measurement-equipment, my first guess is a problem around the CPU/PLL-Board. HF/IF-Stage seems ok due to slightly increased noise when connecting an antenna. This problem seems not to be unique. Other users also have reported trouble after longer periods of QRT. I disconnected and reconnected all plugs to the PLL/CPU-Board with no effect. Any suggestions? mni tnx in advance, Dirk.
