K35DG on Mt. Soledad switched to an ATSC broadcast on channel 35 on May 28, 2015, just one day ahead of an FCC-imposed deadline that would have eliminated their eligibility for spectrum auction participation as a Class A low power TV station. The flash cut was conducted by yours truly with a new Anywave 5X exciter and PA140W power amplifier from RF Specialties. The new system has an ERP of only 150 watts due to spacing restrictions and Mexican treaty limitations. UCSD is retiring its Larcan NTSC transmitter installed in the early 1990’s.
