I'm repairing a Lincoln for someone. Fixed a load of problems with it but one has cropped up just when I thought I had it in 100% working order, that was not there before I started all the work.
The control buttons channel, band, indicator etc do not respond. The frequency dial is OK. The rig will TX when the mic is keyed. If anyone here has one of these radios, can they experiment with simulating a stuck button to see if they get the sort of problem I am describing?
