Comments Due Jan. 12 on NAB, Xperi Digital FM Petitions

Comments are due Jan. 12, replies Feb. 13, in docket 22-405 on petitions from NAB and Xperi for changes to limits on digital FM power levels, said a public notice in Monday’s Daily Digest (see 2210270061). NAB and Xperi want the FCC to adopt an updated formula to allow increased FM digital sideband power levels and combine the proceeding with a 2019 rulemaking requested by NAB, Xperi and NPR on “blanket authorization to originate digital transmissions at different power levels on the upper and lower digital sidebands (asymmetric sidebands).” The proposed changes “will serve the public interest by improving digital FM signal quality and coverage while minimizing harmful interference to adjacent-channel stations,” according to the petitioners.
