To be honest, the most frustrating part is not even the content, but the fact that it is the same content on every station. When I tune from 530 to 1600 KHz, it dosent seem to matter how good the dx is, I dont hear anything within the US worth listening to (unfortunately, my RX stops at 1600)
Then again, an optimist would probably say that the difficult stations between the numerous syndicated satellite repeaters are the real reward for listening, but that dosent mean hearing the same show on several frequencies isnt a little disheartening.
I hear a wide range of programming on the MW band. Daytime, I hear conservative talk, religion, sports, news, South Asian music, Korean programming, Variety talk (new age, in some cases), Russian religion, Mexican ranchero music, Spanish language religion, one classic hits station, one Country station, a fringe-signal business talker and a classic country station. At night you can add several CBC outlets and a rock station to the mix, along with one pop station, a couple stations with classic hits, and a couple more classic country stations (I'm talking dependable signals, not just intermittently received ones).
On FM, if you're talking commercial radio you're talking maybe five formats, in different flavors (pop, hip-hop, AC, rock and country). Seven formats if you add the classic rock and old school urban station. There is a local smooth jazz station but it will go away as soon as it is sold. There is a classical station that is in the commercial part of the FM band, but technically, it's not really commercial per se. Nine or ten formats on FM vs. more like thirteen or more on MW.
I understand your frustration with MW but I've been hearing the same complaints since the 80's when DXers complained about satellite and automated music networks.
