I have been wondering about 830 AM for a little while -- for quite a while I have heard a Spanish-language station beating up on WCCO at night in eastern Iowa. Sometimes WCCO comes booming in as usual, sometimes I hear the Spanish language station in the background, sometimes it replaces WCCO altogether. I wouldn't care, except that aside from DXing, WCCO is actually one of the few remaining AM stations I actually enjoy listening to at night. (Let's face it, the dial is full of syndicated crap.)
I had assumed this was WGUE Memphis, but that can't be right. WFNO New Orleans has a Mexican regional format, but only 750 watts at night supposedly directed primarily out to sea, according to radio-locator.com. I didn't think that 830 AM was one of the frequencies haunted by Cuban stations at night, but on the other hand, the programming I'm hearing doesn't sound Cuban; it sounds Mexican. Does anybody know the story?
