RM-11287 is a multi-party petition that calls for the opening of the AM band to small broadcasters. Two of the five parties involved also filed the original petition for rulemaking that led to LPFM’s conception.
This has been a long time coming: citizen interest in LPAM has percolated since the 1990s, and there’s been open discussion of the idea since at least 2002. In 2003 a respected broadcast engineer submitted a proposal to the FCC which called for the creation of 30 and 100-watt “neighborhood radio” AM stations with 1-5 mile broadcast ranges. The FCC never formally acknowledged receipt of this document. In 2004 efforts were made to revive the proposal, to no avail. Building on these previous efforts with copious field experimentation led to the petition the FCC finally accepted.
