Acting on complaints from a General Mobile Radio Service repeater club in southern California, the US Federal Communications Commission has sent a notice of unauthorized operation and harmful interference to a radio operator whose two GMRS licenses have long since expired.

According to the FCC, the licenses WPQM265 and WQHR501 were not valid on July 27 of this year when agents say Jerry Lee Seehaas repeatedly transmitted siren sounds lasting 6 seconds each on the repeater input frequencies of 467.675 MHz and 467.7 MHz. The FCC notice sent to him on the 4th of November said that agents from the FCC's Enforcement Bureau in Los Angeles traced the sirens to handheld radios he had with him inside a vehicle in El Segundo, California.

FCC records show that Seehaas is the holder of an active amateur radio license KG6UMF. He is also listed as the trustee of callsign KG6OPA on QRZ.com, where the callsign is associated with Seacoast REACT, a nonprofit public-service group that provides emergency communications and assistance at community events.

He was given 10 days to respond to the notice.
