FM Digital Power NPRM ‘Clarification’ Petition Sent To FCC

On October 6, 2023, the time period for filing comments and reply comments on a Notice of Proposed Rulemaking tied to the increase of FM digital power concluded. The proceeding, initiated two months earlier, would change the methodology used by digital FM stations to determine whether they can boost their HD Radio output. It would also allow asymmetric sideband operation.

Now, the Media Bureau has confirmed the filing earlier this month of a “Petition for Clarification,” submitted jointly by the NAB and HD Radio parent Xperi Inc. Why? They detected “an important ambiguity” that requires a clear-up.
