A generic term for an unlicensed beacon that does not follow government regulations for operation (such as Part 15), and are technically illegal.

There are many of these beacons, quite a few are run as propagation experiments. Due to their nature, the exact location of these stations is generally not known, although many are believed to operate from remote locations in the deserts of the southwest USA. Likewise, these stations tend to suddenly appear and disappear from the air. Most run with very low power levels of just hundreds or even tens of milliwatts of power, and are often solar powered, so they can be hidden in open areas. Some are switched via a photocell, so they only operate at night, running off of a battery that is charged during the daytime by a solar panel.

Reported High Frequency Beacons

Freq (kHz) Station ID Operation Notes
2097 A Arizona (15 watts) - 'A' ident or malfunctions as series of dits - 15 watts max., 24/7 (not on air July 08 - needs new battery)
3450 OK OK
4011.8 FL Dasher
4077 MO Photocell switched
4079 TMPnnn The TEMPERATURE BEACON - Temperature in deg. F. in s.w. Arizona - sends 'TMP' then 2 - 3 digit temp. in CW every 10 seconds. 1 watt
4089 . About 80 dits/minute, Death Valley N.P., 24/7, 500 mW to inv. vee. dipole
4094 PA
4096 6 dots 1 Dash
4096.1 Dasher 4.5 sec long dashes (about 13 dashes per min.) Joshua Tree N.P.- big signal - north-facing dipole ('Coxie') 24/7
4096.25 Dasher 1 sec dash (about 30 per min.) Joshua Tree N.P., 400 mW to inverted vee, 24/7 ('Hexie')
4096.6 Dasher 2 sec. dash (about 16 per minute) Mojave Nat. Preserve-400 mW to inverted vee, 24/7 ('Kelsie')
4097.2 Dasher 55 dashes per minute with chirp when sun is low; day-only, Inyo County, Calif. near DVNP at 5300 ft. elevation ('Inyo-whooper'), inv. vee., 0.5w
4102.3 W... The WIND BEACON - sends 'W' ident and series of dits - each dit correlating to a turn of its anenometer, so if it is windy in the s.e. California desert, it sends lots of dits; and no wind, no dits.
5499.13 WA Dasher
5678 CO
6626.2 S About 60-200 dashes per min., Inyo COunty, Calif. near DVNP, sun-only, ~200 mW ('Rocky')
6626.4 Dits Fast 'drippy' sounding dits about 100/min., Mojave N.P., sun-only, 1.5 watts ('Rainy')
6700.4 Dasher About 62 dashes per min., 24/7, Joshua Tree N.P. (Hexy2k)
8001.5 S S.W. Arizona, sun-only, 1 watt. strong signal daytimes
8211.7 OR
10236.7 FL Dasher
14418.3 CO
