While the new Republican-led FCC will no doubt tackle many policy issues in the upcoming months (see our article looking at some of the issues that we expect the FCC will address this year), there are also standard dates and deadlines in February to which broadcasters still need to pay attention. Here are some of those dates:

February 3 (as February 1 is a Saturday) is the deadline for radio and television station employment units in Arkansas, Kansas, Louisiana, Mississippi, Nebraska, New Jersey, New York, and Oklahoma with five or more full-time employees to upload their Annual EEO Public File Report to their stations’ online public inspection files (OPIFs).  A station employment unit is a station or cluster of commonly controlled stations serving the same general geographic area having at least one common employee.  For employment units with five or more full-time employees, the annual report covers hiring and employment outreach activities for the prior year.  A link to the uploaded report must also be included on the home page of each station’s website, if the station has a website.  At this time, these reports appear unaffected by any actions by the new FCC.  While Chairman Carr last week issued a statement suspending all DEI efforts by the FCC, that statement did not specifically mention routine broadcast EEO filings so, until they hear otherwise, broadcasters should continue to observe these deadlines. 

The filing of the Annual EEO Public File Reports by radio station employment units with eleven or more full-time employees or TV stations with five or more employees triggers a Mid-Term EEO Review that analyzes the last two Annual Reports for compliance with the FCC’s EEO requirements.  The Mid-Term EEO Review begins February 3 for these larger radio station employment units in Kansas, Nebraska, and Oklahoma.  Television station employment units in Arkansas, Louisiana, and Mississippi are also subject to this review.  Radio stations located in Kansas, Nebraska, and Oklahoma that are part of station employment units with five or more full-time employees must also indicate in their OPIFs whether their employment unit has eleven or more full-time employees, using a checkbox now included in the OPIF’s EEO folder.  This allows the FCC to determine which station groups need a Mid-Term EEO Review.  See our articles here and here for more on the Mid-Term EEO Review.Continue Reading February 2025 Regulatory Dates for Broadcasters – EEO, Comment Deadlines, FM Duplication Rule, Political Windows, and More

Until recently, to many in the industry, HD radio seemed to be an afterthought – maybe useful in feeding analog translators, but otherwise not very accessible to the public.  But there is now more and more interest in HD radio given the increased inclusion of receivers for this digital service as standard equipment in a majority of new cars.  This means that consumers have ready access to programming on digital FM subchannels that the technology allows, plus the digital sound quality that HD radio provides and the auxiliary data services that can be conveyed along with the audio programming.  This week, the FCC’s Media Bureau issued a Public Notice asking for comments on two technical proposals to enhance service to the public while minimizing interference that the service might otherwise cause to nearby adjacent-channel stations.

Comments are sought on a proposal by the National Association of Broadcasters and Xperi, Inc. (which acquired iBiquity, the company that developed the HD Radio technology) seeking adoption of an updated formula for computing the power level of the “sidebands” on which the HD service resides. The request also asks that the proposal be combined with a 2019 request that FM stations be allowed to operate an HD service with “asymmetric sidebands” without having to seek experimental authority.  What do these requests mean and why might they be important?

Last month, the FCC released a Public Notice requesting further comments on the proposal to increase the power of HD radio operations.  We have written about that proceeding a number of times, including posts here and here.  The increased power for the digital radio signals has been sought by many broadcasters who believe that current HD radio power levels do not  produce strong enough digital signals to penetrate buildings and fully serve radio markets.  On the other hand, other broadcasters fear that the increased power for the digital signals will create interference to existing analog stations operating on adjacent channels.  Today, the FCC set the dates for the filing of these additional comments – comments are due on July 6, with replies due on July 17. 

While comments have already been filed on the proposal to increase digital power, the FCC has raised a number of specific issues on which it wants comments, especially in light of the studies sponsored by NPR in cooperation with a number of other broadcasters, which seek to do a comprehensive review of the interference potential of higher powered digital operations.  NPR is shooting to have that report to the FCC in September.  The specific questions raised in the new FCC notice are:

  • Whether the FCC should wait to decide on the power increase proposal until after the NPR study is done
  • Whether current operations by radio stations operating in HD, and the various tests that have already been run, demonstrate the need for higher power operation on a permanent or provisional basis
  • Whether new standards of interference to adjacent channel stations should be adopted, and if the interference should also protect LPFM stations
  • Whether there should be specific procedures adopted to resolve any interference issues that do arise.
