Well guys, we¡¯ve cracked it, with all your help and suggestions.

?

The culprit was indeed the filter electrolytic C2061 connected to VCC on Mo2002 VCO. It had gone short circuit. I reckon that had dragged down the switching pair Q2016 which in turn had failed.

?

Anyway, I¡¯ve managed to work John on 2mtrs across the shack..... it¡¯ll never be a candidate for the million-miles-per-watt award but we are dead happy.

?

Many thanks again all for your help.

Hi Charles, thanks for that, well I hope you are right, I certainly don¡¯t want to try and source that VCO. I¡¯m going to try and find time tomorrow to check that out, its an easy smd part to remove so it should be a quick check. I¡¯ll let you know.

Thanks Charles.
