AM radio stations that want to improve their service area with a clearer signal can do so by using an FM translator, which receives the AM signal and re-broadcasts it on an FM frequency. This is particularly useful for the many AM stations forced to reduce their power at night, since the FM translator can operate at the same power 24 hours a day.
At issue is a current FCC rule that may make finding a location for these translators unnecessarily challenging. Under the old rule, an AM station could place a rebroadcasting FM translator either within its daytime service contour or within a 25-mile radius of its transmitter, whichever distance was less. The new rule allows the rebroadcasting FM translator to be located anywhere within the AM station’s daytime service contour or anywhere within a 25-mile radius of the transmitter, even if the contour extends farther than 25 miles from the transmitter.
The Commission first authorized AM stations to rebroadcast over FM translators in 2009. In 2016, two filing windows opened that enabled more than 1,000 AM stations to acquire and relocate FM translators to rebroadcast their signals. Because of these actions, nearly 2,000 FM translators are currently rebroadcasting AM station signals, allowing many AM stations previously forced to reduce or eliminate nighttime power to now provide 24-hour service to their communities.
The Commission stated that Thursday’s Order furthers its efforts to assist AM broadcasters in providing vital radio service to consumers throughout the country.
The National Association of Broadcasters thanked the Commission for changing the rule that will make life easier for some station owners. “Broadcasters appreciate chairman Pai’s leadership on the issue of AM revitalization, and we will continue working with him and commissioners Clyburn and [Michael] O’Rielly to strengthen the AM radio band,” it said in a statement.
