Radio ignition noise
« on: July 16, 2010, 08:00:07 AM »
Both radios in my A36 (E632), are experiencing what sounds like ignition noise that varies with RPM.  I hear the noise in the #1 radio, a Garmin 530, only when I receive a transmission.  However, I hear the popping noise anytime the #2 KX155 is turned on.  My mechanic grounded some of the ignition wires & cleared up about half of the noise.  Any thoughts on a diagnosis? Thanks & I hope to see you in Oshkosh.
