The FCC denied reconsideration on the last phase of the digital television transition – requiring that all LPTV stations and TV translators cease analog operations and be operating digitally by September 1, 2015. See our summary of the original ruling on the digital conversion of LPTV and TV translator stations here. In denying reconsideration, the FCC determined that the September 1, 2015 date will hold – denying requests that the final decision be postponed while the FCC considers the repacking of the television band as part of the incentive auction process to clear part of the TV spectrum for wireless broadband purposes. The FCC also noted that some parties wanted to keep operating in an analog mode on TV channel 6, as the audio can be received by FM receivers (so-called "Franken FMs"). The Commission determined that using Channel 6 to provide an audio service this was not a sufficient reason to keep analog operations on TV channels alive past the deadline that they have established. (See our articles about these hybrid LPTV/FM stations, which take advantage of the fact that Channel 6 is adjacent to the FM band and that analog TV used an FM audio system, here).
The Commission did note that, in response to some petitions for reconsideration, that any LPTV station or translator moving to Channel 6 for digital operations be required to protect noncommercial FM stations that would be operating on adjacent frequencies. While the Commission does not expect that such interference will occur frequently, they made clear that LPTV and TV translators are secondary services, and they cannot continue to operate if they cause interference to primary services, including primary noncommercial FM stations.
