Warning: war story. When I was in the Air Force, was stationed for 3 years in Roswell, NM. At night, we usta listen to KOMA, Okla City, on AM. Would come in for awhile & fade out, then back in. Music they played was better than local Roswell station KBIM. (How do I remember that after 50 plus years...) Also listen to Wolfman Jack, XERB, out of Mexico. Both those stations had powerful AM at night. I think we also picked up a Chicago station, WGN??? We do have a local Phoenix AM station that plays oldies but moldies in the day time. Can't remember listening to AM at night, probably cuz I'm home watching Velocity channel.
