Desert Beacons, etc.

2097.38 kHz - 'A' - central, Arizona (20 watts - the "Power Beacon") - 'A' ident., 24/7 in summer, prone to shudown due to depleted battery in winter time at about 0300 local time.

4079.39 kHz: '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

4088.8 kHz: about 80 dits/minute, Death Valley N.P., 24/7, 500 mW to inv. vee. dipole - hrd in Canada - radiates especially well into southeastern Arizona.

~4060 +/- kHz (VFO): Inyo County, Calif., (occasional) 'TR' ident in CW when op. goes on trips; AM music when op. takes bike rides, etc. plays music some mornings around sunrise or a bit after for a while, 250 mW carrier - 500 mW PEP to inv. vee. (was 6710 formerly). (This beacon on average drifts 2-3 kHz night to day with temp. swings inside house).


Mojave Desert 4096 kHz cluster:

4095.82 (night) kHz: 4.5 sec long dashes (about 13 dashes per min.) Joshua Tree N.P.- big signal - north-facing dipole ('Coxie') 24/7 hrd in Canada in 2001 by myself, and west Texas in 2006, along with the other 4096 dashers. The 4096 nightime trio gets out well even to Maryland. Heard during the winter of 2008 with oddly shifting carrier frequency up at around 4096.0 in the mid-morning.

4096.24 kHz: 1 sec dash (about 30 per min.) Joshua Tree N.P., 400 mW to inverted vee, 24/7 ('Hexie') hrd in Canada, MD, etc. This was first put on-air December 1997! Hexie has a very reliable signal.

4096.59 kHz: 2 sec. dash (about 16 per minute) Mojave Nat. Preserve-400 mW to inverted vee, 24/7 ('Kelsie')

4097.25 (centered) kHz: 55 dashes per minute with downward freq. chirp when sun is low; day-only, Inyo County, Calif. near DVNP at 5300 ft. elevation ('Inyo-whooper'), inv. vee., 0.75w


4102.4 kHz: '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. hrd in Canada and in Maryland.

4103.8 slow "O" (night only) ~15 mW output on 12 volt alkaline-D-cell-battery pack. Near Boundary Peak, Nevada. Hrd in w. NM; s.e. CA

5205.3 kHz: 100 dits/min - Saline Valley, Death VlY N.P., morning-sun-only to noon., no nights. 0.5 watts ('Sally') - suffers bad QRM from 'sweeper.' Hrd all over California, AZ.

5484.0 kHz: 'SD' so. California - intermittent - when op. goes on trips (or is not DXing), then 24/7.

5499.1 kHz: s.e. Washington - The SE Washington dasher on 5499.1 is reportedly 85 mW; hrd in Oregon.

6626.2-.3 kHz: fast 'drippy' sounding dits about 100/min., Mojave N.P., sun-only, 1.5 watts ('Rainy') - really gets out well.


the 'Rainy' MNP 6626.5 kHz beacon

6626.2 kHz: HIGHLY VARIABLE - a "trill" of very fast dashes - 40 per second sometimes., Inyo COunty, Calif. near DVNP, sun-only, ~200 mW ('Rocky') - DIT RATE VARIES WITH SUN-INPUT ON 9v PANEL. Fast keying rate due to bad keying (RC) cap. in the circuit. Still, it gets out well sometimes.


A new spectrogram of the 6626 pair.


Spectrogram of the daytime-only 6626 KhZ desert beacon pair ("Rainy and Rocky").

6700.4 kHz: about 62 dashes per min., 24/7, Joshua Tree N.P. (Hexy2k) - not as high ERP as the 6626 pair.

8000.5 kHz: 'S' s.w. Arizona, sun-only, 1 watt. strong signal daytimes all over the West (Fixed 05 April 2009)

8211.6 kHz: "OR" - n.e. Oregon 24/7, good sig. 200 mW max.-hidden in forest.

most of these beacons get out well... most employ dipoles of various configurations.





~4089 kHz Death Valley N.P. - heard in w. and c. Canada well too..




(former) NVIS beacon (fast dasher 250/min, 4096.4 kHz) - relocated and freq. changed since these 2005 pics. were taken...




4096 LSB mode - 19 July 2005, Kenwood R-1000, recorded near Mt. Whitney

All less than 400 mW (A1-mode) powered by the desert sun!
