The good news for classical music on radio is that New Orleans has a new classical outlet at 104.9 FM. It's only a translator--not a full-power station--but it's a start.
The bad news is that commercial classical station WBACH in Portland, Maine is no more. It was rather unceremonially pulled off the air over the weekend.
