I agree with previous posts about the TR-7. I got mine used when I became a
ham 24 years ago. It started developing an audio problem, and digial readout
problem, but removing the boards, deoxit on the pins, and reseating solved
everything. A touch-up on the alignment and it's a brand new radio. The
wb4hfn extender boards are a good buy also.
