Fla. LPFM Gets Interference Notice

FCC says spurious emissions were on aviation frequencies

Federal Aviation Administration, FAA, WBVL(LP)Two radio station licensees in Florida have received notices of violation from the Federal Communications Commission for spurious emissions.

In one case, the commission believes a low-power FM station was causing interference to aviation frequencies at Orlando International Airport. In that instance, the Enforcement Bureau issued a notice of violation to WBVL(LP) in Kissimmee, Fla., licensed to Sucremedia Inc.

The commission says the Federal Aviation Administration began receiving interference to aviation frequencies on Dec. 15, 2020. The interference was reported to the Enforcement Bureau on Dec. 26. The next day, the bureau’s Miami office investigated.

It said WBVL is licensed on 99.7 MHz at a maximum effective radiated power of 89 Watts, but the FCC said its agents measured excessive spurious emissions from the station transmitter on six frequencies — 114.145, 115.850, 118.385, 120.995, 134.585 and 135.765 MHz.

The rules in this situation require that the LPFM stop operations within three hours. The FCC says it made numerous attempts to contact the station but that WBVL didn’t go off the air until at least 41 hours later.

Once WBVL was off the air, the interference to the Orlando International Airport ceased.

In a separate case this week the Miami office issued a notice to Cornerstone Broadcasting Corp. for spurious emissions on 133.0626 MHz that the FCC attributes to Cornerstone’s FM translator at 97.3 in Deland, Fla. That translator serves WJLU(FM) in New Smyrna Beach.

In both cases the FCC has instructed the licensees to provide information about the emissions and any steps they have taken to resolve the situation, while reserving the option of taking further action.
