LIST OF RADIO STATION CLASS CODES
An unofficial list for use by DXers This list is mainly derived from ITU, US NTIA & FCC and ERO documents but is a modified form for use by DXers in the classification of radio stations. |
| TERRESTRIAL RADIOCOMMUNICATION SERVICE STATION CLASS CODES |
|||
| Land Stations are not intended for use (to transmit) while in motion. Mobile Stations are used (to transmit) while in motion or during halts at unspecified points. Repeater Stations consist of a radio transmitter, a radio receiver, and coupling between the two so as to retransmit unchanged in intelligence the received signal. A -R suffix added to any code indicates a repeater. Some codes already contain the R Repeater suffix. |
