Sixth Report and Order: Difference between revisions

Once the Commission receives a bona fide complaint of interference from an LPFM station operating pursuant to a second-adjacent waiver and notifies the LPFM station of the complaint, the LPFM station must “suspend operation immediately” and stay off the air until it eliminates the interference or demonstrates that the interference was not due to its emissions. The FCC concluded that an LPFM station may demonstrate that it is not the source of the interference at issue by conducting an “on-off” test. “On-off” tests have been used by the FM translator and other services to determine whether identified transmissions are “the source of interference.” In addition, the Commission specifically authorized LPFM stations to use “on-off” tests for determining “whether [third-adjacent interference] is traceable to [an] LPFM station.”196 As the Commission did in that context, they will require the full-service station(s) involved to cooperate in these tests.
