Picked up a 95 SC Riv recently and this forum has already helped on what I thought was a cooling fan issue which turned out to be normal. My problem is radio reception. Antenna goes up and down, but I get only one station and it is very weak. If I unplug the antenna the station goes away. I am thinking/hoping that something is bad in the antenna and it not being the head unit. I plan to try a spare antenna to see if that fixes it. Has anyone had this issue.
