LowFER

LowFER (Low-Frequency Experimental Radio) is a license-free form of amateur radio practicised in the United States and Canada on frequencies between 160 kHz and 190 kHz. LowFER-transmitters may not use antennas longer than 20 metres or powers more than 1 Watt. Telegraphy modes are the most common transmission modes, but speech transmission via Amplitude modulation (AM) or Single-sideband modulation (SSB) is also allowed. In Europe the LowFERs band is used for broadcasting and is unavailable for amateur use.
