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.

There is a message board where listeners can report reception of beacons, it is also useful to see what other folks are presently hearing: HF Beacon Loggings

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 (back on the air, recently reported on 6 April 2009)
3450 OK OK
4011.8 FL Dasher
4062 C Very drifty, but slow drift, logged form 4052 to 4063. Its morse is not timed correcctly, it is probably sending a C with a short first dah (longer than dit, shorter than dah), but it could be an ER with a long dit, or a TR with a short dah. 24/7 Location: SW, probably CA
4078.14 WW 300-400 mW Inverted L night time only Location: Colorado
4077.27 MO Solar 200 mW 118ft end fed wire 24/7 Location: Oklahoma
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
4094.2 PA Solar power 200 mW Dipole 24/7 Location: Arkansas
4094.8 Dasher Sputnick - 60 dash/min, night only Location: West Virginia
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
4097.4 KX "KX" ten times, then "TEMP IN F", then the temp (three times) inside the enclosure, then "TEMP OUT F", and the outside temp, again three times.
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.
4194 MX Xtal controlled milliwatt beacon operated occasionally in europe. Sometimes sends straight carrier instead of ID.
4608 MXC Xtal controlled milliwatt beacon operated occasionally in europe. Sometimes sends straight carrier instead of ID. Sister beacon to MX.
5157.6 Dasher BLINKY 200 mW Dipole 24/7 Location: Florida
5484 SD San Diego, CA
5499.13 WA Dasher
5678.4 Dasher PIKE solar/battery 100 mW Dipole 24/7 Location: Colorado "Honker"
6549.3 FL 300 mW Dipole 24/7 Location: Florida
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)
7998 UFO CW Tone Modulated
8001.5 S S.W. Arizona, sun-only, 1 watt. strong signal daytimes
8003 Dasher Solar/battery dipole 24/7 Location: Colorado "Pike JR" 84 dashes/min
8188.7 W Solar/battery 100 mW dipole daylight /7 Location: Colorado
8211.7 OR
8261 F 250mW into a 1/2 wave inverted vee, 1400-0500, location: Western Canada
10236.7 FL Dasher
11002.7 CO Solar battery 300 mW dipole 24/7 Location: Colorado
