radio
 

I have a 1985 380sl that I just purchased, does anyone know anything about the radio system? I can
only get 2 local stations on FM and on AM I receive nothing. I checked the connection to the
antenna,it appears to be fine. I also can tell when the radio is first turned on the signal gets better as the antenna goes up, this makes me think it is not a problem with the antenna but rather the tuner in the radio, any comments?
