"The Federal Communications Commission received a complaint from 
Allegheny County Pennsylvania Emergency Services (Allegheny County) 
concerning interference to its 911 emergency communications channel 
operating on 470.4375 MHz in Pittsburgh, Pennsylvania.

"On July 30, 2025, Agents from the Columbia Office of the FCC’s 
Enforcement Bureau (Agents) conducted an investigation and determined, 
using direction finding techniques, that the source of the interference 
to the Allegheny County system was a signal emanating from the residence 
of David O. Knudtson (Knudtson), licensee of amateur radio station KD3ASC.

"After the Agents notified Knudtson of the interference issue, he 
produced a handheld radio (identified as a BTech UV-Pro). An examination 
of the radio determined that it had been modified to monitor the 
Allegheny County channel, and its “Audio Relay” feature had been 
activated. This feature turned Knudtson’s radio into a simplex repeater 
that was re-transmitting the Allegheny County channel.

"Knudtson surrendered the radio to the Agents. Subsequently, the Agents 
verified that the interference to the Allegheny County system had ceased."
