"Look For The Label!" Make sure that transmitter is certified.
The recent situation at KLIE-LP has drawn attention to the unique aspect of the LPFM rules where a lab-tested certified transmitter model is required in the service.
The certification requirement dates back to the 1990s prior to the establishment of the LPFM service with the surge of pirate radio operations that took place following the passage of the Telecom Act of 1996 which opened the door for the relaxing of the national ownership rules. The certification requirement was to assure that unstable pirate equipment was not used in the licensed service.
