rookie Posted October 7, 2016 Report Share Posted October 7, 2016 After a summer of being grounded due to radio problems my frustration has reached a high point. At the end of June I prepared to fly only to find my radio would not power up, everything else was fine but no radio. After a couple of weeks I received it back from the factory and went to fly again, radio worked but had this static that sounded like what is referred to as alternator whine. It would increase or decrease with engine speed. Didn't get very far trying to trouble shoot because a week later it wouldn't power up. Back to the factory where they say it bench tested fine . After wringing out the harness to prove to them it was okay they agreed to send me a loaner to see if it would power up, it did. Back to the factory again, in the mean time I tried flying with the loaner but it too had the alternator whine. Waited to get my unit back since I still didn't know if it was a radio problem or engine. Finally received my unit back and whine is stil there, checked connections and replaced capacitor with much larger unit.No joy!!!! Only thing that works is to turn the radio off. Turning alternator off or intercom down has no effect. For what it's worth this radio has never been a problem and reception has been excellent. It appears that the whine and not powering up happened at the same time although not necessarily connected. Anyone had a similar experience or a clue of what I can do now. Missed all of the summer and maybe the fall, by the time I get back in the air I hope I can still fly the bird. Al Meyer Link to comment Share on other sites More sharing options...
