'89 sabre - static on radio while...

[od1exx]

-opening/closing the Windows.
-honking the horn.

other than that the radio stations come in perfectly clear.

also, when i try and use my iPod w/ iTrip in the vehicle I cannot get a good signal (i could in my other vehicle so i know its not the iTrip or iPod) no matter what station i tune it to. when i grab the iPod w/ iTrip in my hands though the static seems to dissipate somewhat.

all of this seems like a grounding issue to me but i am really not too sure, if anyone knows what this could be caused by plz tell me and inform me on how to fix it! thx.
