Ejection Handle Pulled
This is one of those situations where it would be good to have a handheld in the flight bag. I have had a Sportys handheld (the older model without the ILS) for years, and needed it only one occasion flying IFR from the Charlotte area to Raleigh. The audio panel had a freak out, but I managed to talk with Greensboro approach on the handheld and within 15 minutes, the Nav/Coms were back up and working fine (wound up being a bad diode or something like that). Anyway is was handy to have. The radio still works fine, I just replace the AA batteries the same time as annual every year and do the occasional radio check.
I had a similar issue. Both coms went down within 5 min. Of each other for unrelated reasons!? Anyway, I had a handheld but it would not turn on, which was frustrating to say the least. Turns out that the battery connections had developed an invisible oxide coating. So now I put a light coating of dielectric grease on the connections. Now it always turns on.
