My Narco Mark 12-D Aircraft Radio Test

[@jerrydaugherty3781]

When I had a share in N3628S we had Narco MK12 Nav/Com radios worked great, the plant closed and several pilots started pushing the panic button worried about future service, as far as I know several avionics shops kept right on servicing them to this day.

100% correct you are Jerry. The display's were one of the weakest issues but the good news is Vishay still makes them and they are relatively easy to replace.
