Fishnet beacons, also known as Drift Nets and Fishing Buoy Transmitters, are low power transmitters which periodically send [[CW]] identifiers followed by a carrier. The average repetition rate is about 4 minutes. They are battery powered and use fairly small and  inefficient [[antenna]], however they can be heard for hundreds or even thousands of miles. Fishnet beacons are can be found between 1.6 and 4 MHz, and are most often found in and above the 160-meter [[amateur radio]] band.

A typical driftnet radio buoy Radio Buoys

Fishnet beacons, also known as Drift Nets, Fishing Buoy Transmitters, Radiobuoys, Radio Buoys, Radio-Buoys, and Fishnet Buoys are low power transmitters which periodically send CW identifiers followed by a carrier. The average repetition rate is about 4 minutes. They are battery powered and use fairly small and inefficient antenna, however they can be heard for hundreds or even thousands of miles. Fishnet beacons are can be found between 1.6 and 4 MHz, and are most often found in and above the 160-meter amateur radio band (1800-2000 kHz or 1.8-2 MHz) They are typically used by fishermen to locate nets, hence the name.

There are reports of similar beacons operating in the 26-30 MHz range (including inside the 11 meter CB band and 10-meter amateur band). They follow a very similar format, transmitting a varying-number of characters ID with low power.

Typical transmit power is in the 3 to 10 watt range.
