1380 kHz

 

The AM frequency of 1380 kilohertz is defined by the FCC as a Regional Channel Class B or D frequency.  In Idaho there are no stations on 1380, but we include this frequency because KSRV in Ontario, Oregon serves the western part of the Treasure Valley. Across the US, however, there are over 60 stations assigned to this frequency, several in Canada, and several  in Mexico and other North American areas.  It is for this reason stations on this frequency either reduce power or switch to a directional antenna (or both) at night to reduce interference.    Some stations on 1350 operate only during the daytime hours.   (Information updated March 2014)
