Channel 200 is 87.9; 201 is 88.1, and so on up to 300 which is 107.9.
There are two stations in the entire U.S. on channel 200: KSFH, a high-school station in Mountain View, Calif., and K200AA, a Calvary satellator in Sun Valley, Nev. In addition, Federal Signal Corp. has an experimental license for WA2XNX in Brazos, Tex., but I have no idea if this station is operating.
Channel 200 is reserved for non-commercial, class-D stations which have been "bumped" by a primary station from their previous channel, and for which no other FM channel would be technically permissible. I suspect this rule was made specifically for KSFH, which was for many years the only station on the channel; K200AA was just recently built.
