Whine in headset
After installing a new radio, audio panel, and stereo headset jacks, I have introduced some sort of electrical whine into my audio system. The tone seems to be RPM dependent - high RPM = higher pitch. The whining sound seemed to be intermittent, but there wasn't anything apparent that made it cut in and out. Could be heard through both Lightspeed and Bose headsets in pilot & co-pilot jacks.
Reading some old posts, it sounds like it is likely related to the alternator? Some have fixed their problems by replacing diodes or noise filters (that's getting above my current knowledge level at the moment)? I did all of my own wiring on the upgrade, and I think it is more likely that my inexperience has somehow caused this than rather something failing on the alternator coincidentally.
What else could I be potentially looking for? While researching and learning, I kept reading about ground loops. What does that actually sound like? I am currently under the impression that a ground loop is more of a static sound than a whining sound.
