The NPRM proposes a one-time filing window for AM licensees and permittees, “which will allow each to apply for one new FM translator station to fill in its service area,” she said. It proposes to relax the AM daytime community coverage rule “to allow existing AM broadcasters more flexibility to propose antenna site changes,” she said. There also is a proposal to eliminate the AM “ratchet” rule, which requires an AM station to “ratchet back” its nighttime signal to reduce interference to certain other AM stations, Clyburn said.
