KPBS-FM 89.5 in San Diego can now fire up its legacy site on Mt. San Miguel in the event of some failure or maintenance needs at Mt. Soledad. The FCC issued the license this week. You might remember that the San Diego State University NPR affiliate moved to La Jolla last year, increasing power and overall increasing service to its strong donor base to the north and west. It only made sense to maintain the equipment at Miguel for backup purposes since the TV transmitter remains there anyway, and that’s what they’ve done.
