FCC GMRS Interference Notice Details Southern California Investigation
Back to Radio in the NewsAn FCC GMRS interference notice issued Nov. 4 orders Jerry Lee Seehaas, KG6UMF, to stop unauthorized transmissions and harmful interference. Agents traced repeated siren signals on two Southern California repeater inputs to radios in his vehicle in El Segundo, California, the notice says.
The enforcement notice required a response within 10 days describing steps to prevent further interference. It does not impose a fine.
Seehaas, of Oceanside, California, holds an amateur radio license, but the FCC says he had no valid GMRS authorization on the investigation date.
FCC Agents Traced Signals to a Vehicle
The investigation followed complaints from a General Mobile Radio Service repeater club about interference affecting operations on 462.700 and 462.675 MHz. On July 27, 2026, agents from the FCC’s Los Angeles field office detected repeated siren transmissions lasting about six seconds on 467.700 and 467.675 MHz, the repeaters’ input frequencies.
The agents traced the signals from a moving vehicle to handheld radios inside the vehicle after it stopped in El Segundo. According to the notice, Seehaas returned to the vehicle after agents identified themselves. The agents verified that the interfering transmissions stopped shortly afterward.
The FCC GMRS Interference Notice Cites Two Violations
The notice cites Section 301 of the Communications Act for unauthorized operation and Section 333 for willful or malicious interference. It also cites the individual GMRS license requirement in Part 95.
The letter warns that violations may lead to monetary penalties, seizure of radio equipment and criminal sanctions. The Enforcement Bureau says it will consider Seehaas’s response and other relevant information in deciding what further action, if any, is required.
FCC Records Show Two Expired GMRS Licenses
The FCC says its records showed no license authorizing Seehaas’s GMRS operation on the date of the investigation. His two former GMRS licenses, WPQM265 and WQHR501, expired in 2005 and 2012, respectively. Neither his amateur license, KG6UMF, nor his role as trustee of amateur club station KG6OPA authorized those transmissions.
