LowFER (Low Frequency Experimental Radio ), the radio operating on long wave in amateur radio or by other experimental radio services.

In ITU Region 1

In the 2.2 -kilometer band of frequency range from 135.7 to 137.8 kHz is an amateur band for amateur radio available. The maximum transmit power is 1 W ERP and frequency allocation on a secondary basis allows no interference to the primary users ( maritime and land mobile ).

In ITU Region 2

In the U.S. and Canada transmitters may be operated without a license for voice, telegraphy and data transmission in the frequency range between 160 kHz and 190 kHz, where the radiated from the antenna power does not exceed 1 watt and no antenna is used with more than 10 meters in length.

As in Regions 1 and 3, this frequency range is occupied by very powerful radio transmitters ( long wave radio ), the traffic with American LowFER transmitters is there only a very limited extent. In this frequency range both the Fixed Radio Service ( entry 17001 in the Frequency Usage Plan) as well as the maritime mobile service Mobile ( entry 17001 in the Frequency Usage Plan) is provided.
