Hi Garey and a few others, Many thanks for your help sorting this out. I exchanged C320 on the TX-exciter board and made sure all the grounding is in proper order. The carrier is still audible but a lot weaker then when I started! I think C320 had the main effect, however if I measure it it reacts as a normal electrolith... The carriersuppression is now in the order of 45 dB down and I think this is as good as I can get it.
Thanks again, this list houses some REAL hams :) 73, Dick PA2DW
