Thanks for all the info - I'm not going to be fanatical about it though! Much more interested in tracking an aircraft across the North Atlantic!

The DW transmitter is still going strong, almost a year after it was deployed to the desert in February of 2021. The transmitter crystal seems to have aged upwards about 50 Hz

And it's still a fine prop beacon.

2097.3 "A" Fairly high power, an easy target even out east. Back on air Nov 2021

4086.7 dasher sends about 8.7 dashes / min, each about 1.7 sec long

4094.0 id's UFO TMP three times, after TMP two numbers are sent then back to dashes. On the air around Nov 2020

Next sends 5 slow whoops, BAT & 3 digit voltage, O TMP then 2 digit temperature, I TMP then 2 digit temperature, PV and solar panel current with values ranging from 0 to over 2000 in milliAmps.

4096.0 "Coxie" Slow dasher, about 4.5 seconds, 700 mW, Joshua Tree NP, daytime only with dead battery

4096.2 Slow dasher called Buddha, was "Phallaxy" was "Viking". About 30 mW, daytime only. On for 3 seconds, off for 3 seconds

4096.85 "Marin Dit", 24/7 5-10 mW, harmonic of 8193.77 radiates better

4106.86 About a 2 sec dash followed by a 5 sec space

4109.50 "Central Coast Slider" slow whooping beacon, coastal mountains of central CA, 335mW, EFHW antenna, solar/battery power

4175 Z

5644 Y and 2 second dash

6626.2 "Rainy" - Mojave NP, CA - daytime ditter/chirper in Mojave NP, 1.5 watts, first on-air March 2003

6627.0 Gendarme - a whooping beacon, quick-falling in-freq. deliberately the result via a 100 uF cap. on the voltage rail from the 2w panel and the freq. falls during cap. discharges on key-on. 50% duty-cycle/0.5 watts. Somewhere in the southern Great Basin... sun-only

6700.5 "HexY2k" Joshua Tree NP, daytime only, 100 mW to inv. vee, 150 mW first on-air 29 Dec. 1999

7000.65 "Stumpy" Ditter, about 0.17 seconds long, sent every 22 seconds.

7039.4 "T" beacon OK0EPB sends a marker each second, a longer one at the minute, and callsign.

7956 kHz Cry Baby 1/second dasher with chirp, 10 mW solar powered daytime only. Located East of The Continental Divide somewhere high in the Rockies. On the air May 19, 2021

7997.0 kHz dasher appears to be a 2 second on, 2 second off, dash. may be related to 4997.08 dasher

7998.3 "Shorty" sends 18 dashes starting every minute.

7998.9 Ditter, dits about 0.15 secs long, about every 0.6 secs, or about 100 dits / min

7998.9 KHz, dashes of roughly two seconds long with about five seconds inbetween dashes

8000.35 Very long period dasher, 40 or 50 seconds. Sometimes sends a broken dash that sounds more like an A or AE.

8001.2 New beacon as of Dec 20, 2015, 5 second period, frequency 8001.2 - 8001.6

8005 "Hiker", Dit rate is 60 per min. 500 mW into whip antenna.

8006.7 V5 sent 39 seconds apart

8191.9 second harmonic of Coxie on 4095.9

8193.7 "MarinDit" - 24/7 in Marin County, CA - about 80 dits/min. 10-15 mW only - on-air since spring 2000 (an "attic beacon"), this is the second harmonic

8200.15 D, repetition 3 seconds

8498.5 Fast Dasher dits are about 0.14 sec long, and about 0.6 sec apart, or about 100 dits / min

Cool. I've listened for some of these beacons, haven't yet heard one, though...
