I have a basic Vans 60 amp alternator with the built in regulator. I also have a stereo intercom with several music sources. I get the typical alternator whine in my headsets most noticeable when listening to music but also present on COM and just plain intercom. The strength of the whine depends on how much the battery is being charged or how much current the alternator is generating. It is loudest immediately after engine start or when I turn on ALL my lights, strobe, nav, landing and taxi. The battery is new and this is really a fairly typical problem in aircraft but it is annoying and I would sure like to eliminate it if possible.
What I?m looking for is advice from someone who has personally experienced and SOLVED this problem. I appreciate suggestions but I really don?t want to try this and try that, etc. I suspect a filter on the alternator output may be the solution but there are many types, capacitors, inline filters (chokes/capacitors) etc. I?ve dealt with similar problems on old cars and I know you can spend a LOT of time trying different solutions and sometimes never really solve the problem therefore I?m asking for someone with firsthand experience to share their solution.
