With the recent changes in the local radio stations, I've been scanning the channels more often. KPFA has some decent classical hours and last weekend I discovered "Panhandle Country", which airs at 3:00 PM every other Sunday. (I believe it alternates with Pig in a Pen.) The host is a bit of a Marxist (so I gathered from his comments about May 1 being the true Labor Day, recognized by the rest of the world and which the U.S. will not adopt...), but the music is excellent. (What should I expect from a radio station located in Berkeley.)

Now if we could get a radio station to replace the loss of classical KDFC. (Which apparently still exists, but covers barely beyond Napa.) KDFC is no longer commercial but is listerner-supported, just like KPFA.
