Newbie here, not an EE, just an old Air Force electronic tech from the 70's...please be gentle. :)
I recently installed a noise suppressor inline to the 12v on my 70 Lincoln AM/FM radio. It cleaned up the "whining" noise just fine - but one interesting side note is that my FM stations come in a LOT stronger, not just clearer. Before I would loose my favorite FM station on the way to work in the same spots each time. After the noise suppressor I get the station strong the whole way.
This is creating a bit of a problem as the grey matter in my head can't seem to come to grips with why this could be.
The only thing I can think of is that the power is totally unfiltered in the radio and the "noise" on the line affected the tuning circuit. I don't have access to a schematic for this radio.
What do you'all think? Why do the stations come in much stronger now?
Thanks in advance!
