A little background:
When I bought my airplane, COM #1 was a Narco MK12d+ TSO. Worked fine. After many months, it started to have some intermittent transmit problems, carrier only, but would receive fine. It worked sometimes and not others and eventually just stopped working (meaning it would receive, but would transmit carrier only).
I bought another radio, used of course, stuck it in and it worked great! I got about 30-45 days out of it before it burned up. Nasty smell, no receive, no transmit, but screen lit up.
So, at this point I've got two radios that seem to have gone from working to not, in that slot, inside of a relatively short period.
I sent the second radio off for repair and it came back yesterday repaired. Bunch of capacitors blown, holes in the board, etc. All fixed now and an 8130 and yellow tag. But, I'm afraid to put it in!
Right now, I'm running COM 2 for most of my needs and the Narco that will receive only as my "ATIS getter". Works OK.
I'm afraid to put the freshly repaired unit in only to have it burn up again. For those with experience in these matters, does it make sense that the mounting tray and/or wiring in the airplane is leading to these two broken radios? If it was one, I wouldn't think anything of it. But, it's two radios in as many months it seems.
What due diligence can I do to the wiring and mounting tray before sliding in the repaired radio on which I just spent over $600?
