Most, but not all, third-adjacent separation requirements for LPFM stations set to go away as of June 4, 2012.
For those of you keeping score, the third-adjacent channel separation requirements for low power FM (LPFM) stations are about to be history – like they were back in 2000, before they were reinstated in 2001, at Congress’s express direction. But last year Congress had second thoughts, and so it’s “see ya” once again to the third-adjacent protections . . . except that some will still be with us.
As previously reported, the Commission has recently devised a complex Rubik’s Cube approach to sorting out the longstanding stalemate between FM translator applicants and the LPFM Insurgency (since LPFM is by definition a not-for-profit undertaking, it’s hard to call it an “industry”). But that was only part of the FCC’s recent LPFM-related work. In a separate decision – formally titled (deep breath first) the “Fifth Report and Order, Fourth Further Notice of Proposed Rulemaking and Fourth Order on Reconsideration” (5th R&O) – the Commission has complied with Congress’s “unambiguous” direction and has tossed the on-again-off-again third-adjacent channel separation requirements applicable to LPFM stations.
The resulting rule changes, set out in the “Report and Order” portion of the 5th R&O, have now been published in the Federal Register. That sets the effective date for those changes. Mark your calendars: the changes are scheduled to take effect on June 4, 2012. (The “Further Notice of Proposed Rulemaking” portion of the 5th R&O contains a welter of proposed rule changes. Those have not yet been published in the Federal Register. We’ll address them in a separate post.)
The changes that have just been adopted are relatively narrow.
In the Local Community Radio Act of 2010 (LCRA), Congress told the Commission to get rid of the third-adjacent minimum spacing requirements between LPFM stations and other FM band occupants (i.e., full-service FM, FM translators and FM boosters). How hard can that be? Just hit the Delete button every time “third adjacent” shows up in the LPFM rules, right?
Not so fast.
While Congress “unambiguously” wanted the Commission to deep-six third-adjacent protections, Congress also wanted to protect radio reading services (RRS) that operate on subcarrier channels which are particularly susceptible to (wait for it) third adjacent interference. So if you eliminate all third-adjacent separation requirements, which Congress wants, you threaten RRS operations, which Congress doesn’t want. Oops.
No worries. As it turns out, the Commission’s rules already included extra protections for stations carrying RRS on their subcarriers. Those rules, initially adopted back when the FCC first abandoned third-adjacent protection requirements for LPFMs in 2000, had become “redundant” when the requirements were reinstated the next year (at Congress’s insistence). Despite their redundancy, the Commission never got around to deleting the RRS protection rules. Good thing, since they will come in handy now that Congress has ordered those protection un-reinstated. As a result, Sections 73.807(a)(2) and (b)(2) of the LPFM rules will continue to contain some third-adjacent limitations on LPFM stations.
Oh, one more thing. Third-adjacent channel protection requirements applicable to LPFM stations in border areas will also remain in place. Treaties with Canada and Mexico impose such requirements, and nothing in the LCRA suggests that Congress intended to unilaterally revise those treaties.
While prospective LPFM applicants can presumably figure out fairly easily whether they’re close enough to the border to have to worry about the residual third-adjacent limits, the RRS question is another problem entirely. The FCC generally doesn’t regulate, much less keep track of, subcarrier use. As a result, figuring out what stations are actually carrying RRS on their SCAs may be a tad problematic.
Bottom line: Consistent with the will of Congress, third-adjacent minimum distance separation requirements for LPFM stations have been tossed . . . except (a) in border areas or (b) when the third-adjacent full service station happens to be providing RRS. The elimination (or, more accurately, semi-elimination) of these requirements is set to take effect on June 4, 2012.
