"Classes for U.S. AM Broadcast Stations
In MM Docket 87-267, the Commission reclassified all domestic [United States] AM stations. These classes are A, B, C, and D. Generally, all U.S. records will have both a Domestic Class and a Region 2 Class. For U.S. stations, the Region 2 Class can be derived from the Domestic Class. Therefore, we explain how to derive the Domestic Class first.
The AM band frequencies are divided into three categories: Clear, Regional, and Local channels. The allowable classes depend on a station's frequency, in addition to other variables. On the Clear channels certain stations are specifically classified as Class A stations or as Class B stations. The other stations have their class determined by their frequency.
Classes of AM stations are defined as follows:
Class A Station. A Class A station is an unlimited time station (that is, it can broadcast 24 hours per day) that operates on a clear channel. The operating power shall not be less than 10 kilowatts (kW) or more than 50 kW.
Class B Station. A Class B station is an unlimited time station. Class B stations are authorized to operate with a minimum power of 0.250 kW (250 watts) and a maximum power of 50 kW. (If a Class B station operates with less than 0.250 kW, the RMS must be equal to or greater than 107.5 mV/m at 1 km at the actual power.) If the station is authorized to operate in the expanded band (1610 to 1700 kHz), the maximum power is 10 kW.
Class C Station. A Class C station is an unlimited time station that operates on a local channel. The power shall not be less than 0.25 kW nor more than 1 kW. Class C stations that are licensed to operate with 0.100 kW may continue to operate as licensed.
Class D Station. A Class D station operates either daytime, limited time, or unlimited time with a nighttime power less than 0.250 kW and an equivalent RMS antenna field less than 107.5 mV/m at 1 km at the actual power. Class D stations shall operate with daytime powers not less than 0.250 kW nor more than 50 kW. NOTE: If a station is an existing daytime-only station, its class will be Class D."
