My radio has started on what I assume to be the decline, because suddenly every single FM station I try to play is inaudible. I know it is picking the stations up, because I can barely hear them when I crank the volume to max. The radio picks up AM great, so I checked both ends of the FM antenna and both are secured nicely and do not appear to be severed or loose. What could be causing the sever lack of sound for FM stations? Thanks.
