My workshop/gunsmithing/reloading is inside a 30x48 metal building. Metal doors, no windows. FM reception is a bit spotty. I had an old FM/AM/ cassette sort of boombox that worked well, but it eventually died. The AM/FM/CD/shelf stereo I have now sucks if the doors are closed, even with an outside antenna. Any recommendations for a radio (really all I do is listen to FM) that has one heck of an antenna/tuner and works well inside a steel box?
