I have been having constant radio static with both of my radios about 10 mins or so after takeoff. I've been doing flight to troubleshoot and talked to my mechanic, he said it could be an alternator interference issues. So I pulled the alt breaker and the static went away. With that said, he said it could be the diodes and not the actual alternator. Is that a costly fix as far as parts and labor? Just trying to plan it out.
