On my 76 there is a AM/FM/8 track player which still works but not well. On AM the reception is almost non existant. I can get multiple stations on portables and other vehicle radios here but in 76 almost nothing.
On FM I get about five stations where I should be getting about 25.
I found the antenna coax on back of radio and unplugged it and reception went dead.
I can't find where the external antenna is for the broadcast radio?
I am thinking it might be broken off at the base????
Then again it might be hooked to the TV antenna which for some reason does not want to go up but have not looked at it from top to see what problem might be.
I see AS antennas on ebay and they are an external hull mount and I can't find where one of these ever was.
Being a ham radio operator I would like to get better reception.
