The FCC has dropped a Sept. 1 deadline for low-power TV and translator stations to convert to digital broadcasting. While full-power stations were required to go digital-only in 2009, LPTV/translator stations have been allowed to stay in analog -- though many have switched to digital voluntarily. The FCC said it is dropping the deadline because the impending spectrum auction could force some LPTV/translator stations to make more technical changes or leave the air completely. (Class A stations, which transmit with the same power levels as LPTV but get extra protections in exchange for compliance with many of the same rules as full-power stations, will still have to meet the Sept. 1 deadline.)
