JA 13998.0 24/7
CO 11002.7Khz 24/7
Pike Jr. 8067Khz 24/7
Pike Dasher 5678.4 Khz 24/7

(e. Colorado Rockies area)

--------------------------------------------------------------------------------

(~ means I forgot exact freq. - I have it somewhere - you figure it out ;] )

~2097 kHz - 'A' - central, Arizona (15 watts) - 'A' ident or malfunctions as series of dits - 15 watts max., 24/7 (not on air July 08 - needs new battery).

3450.5 OK - strong into Colorado and clear freq...(Oklahoma beacon - good for Eastern DXers too) wattage unk. - see right below for alt freq.

4007.5 'OK' Oklahoma - heard at night in AZ - other data unk.might have qsy'd - see new beacon on 3450.5 (above) ident "OK" - strong into Colorado and clear freq...73 friend (via reporter in CO)

~4079 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

~4089 kHz: about 80 dits/minute, Death Valley N.P., 24/7, 500 mW to inv. vee. dipole - hrd in Canada.

~4060 kHz (VFO): Inyo County, Calif., '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).

4096.1 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.

4096.25 kHz: 1 sec dash (about 30 per min.) Joshua Tree N.P., 400 mW to inverted vee, 24/7 ('Hexie') hrd in Canada.

4096.6 kHz: 2 sec. dash (about 16 per minute) Mojave Nat. Preserve-400 mW to inverted vee, 24/7 ('Kelsie')

4097.2 kHz: 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 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.

(qrt) 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' OTH-b radar. NOT HEARD SPRINGTIME 2008 - OFF AIR NOW due to unk. reason - probably animal damage.

5484.0 kHz: 'TSN' so. Arizona - intermittent - when op. goes on trips then 24/7.

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

~6626.4 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 - about 60-200 dashes per min., Inyo COunty, Calif. near DVNP, sun-only, ~200 mW ('Rocky') - DIT RATE VARIES WITH SUN-INPUT ON 9v PANEL

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.

8001.5 kHz: 'S' s.w. Arizona, sun-only, 1 watt. strong signal daytimes

8211.6 kHz: about 62 dashes per min., n.e. Oregon 24/7 - new, good sig. 200 mW max.-hidden in forest.

most of these things get out well...

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

good and very simple HF dasher-bcn schematic
