And speaking of Santa Barbara, KDB-FM is #4 in the latest ratings. It's a straight simulcast now of KUSC Los Angeles. In the ratings both stations combine for #4. But at one time, KDB-FM was one of the last commercial classical stations. So I guess that leaves four commercial classical stations in the U.S.
WFMT Chicago (owned by a non-profit company)
WRR Dallas (owned by the City of Dallas)
KLEF Anchorage
WFCC Cape Cod
In Canada, the CBC Music stations play six hours of classical music in middays. And there are four commercial classical stations:
CFMZ Toronto (always in the top 10 of the ratings)
CFMX Cobourg (serves Ontario between Toronto and Kingston)
CJPX Montreal (in French)
CJSQ Quebec City (in French)
