Well, the coil (filter) made no difference at all; alternator whine is still there and drives me crazy

Couple of things to check.
First remove the redundant ground. The two ground connections can develope a feedback between them (can't remember the "big" words for this offhand). It's best to use only one ground. In my opinion the shorter the better.

Second check and make sure your antena wire is in all the way. If you had to add an adapter check that too. but I think the first is your problem.
