Believe me I was really trying to find that bad connections were the source of
the problem, but no joy. When all this started happening I went completely
through the radio (I'm not shy about taking radios apart) and disconnected and
cleaned every connector contact in the radio and then exercise each several
times during re-mate. That includes removing each board from it's motherboard
connection. All to no avail. I subsequently repeated that scenario many times
over several days thinking I just hadn't hit the magic pin/socket. But after
all the cleaning, pushing, and flexing of every connection and every board on
multiple occasions, I never detected any change or effect on the problem.
But as W2NSD used to say, Never Say Die!
