Currently Active Beacons
« on: January 02, 2013, 2108 UTC »
As it can be confusing to keep track of the various active unlicensed beacons by reading the various messages, I thought it would be useful to keep an up to date message as a "sticky" at the top of this forum. These are for unlicensed (read not legal) beacons. Ham, Part 15, and military beacons are not included. 

As new beacons are discovered, or old ones disappear, this message will be updated. If you think a change is needed to a beacon status, or to suggest an additional beacon, post a message as a reply to this one. Replies will probably be deleted after being acted on, to keep this message tidy (and so we know it's been done!).

I've made several changes to the list. Please let me know if there's any beacons I have missed.

to me the numbers for B seemed to be Battery voltage, but I could be wrong   ;D

4102.74 Windy sends W followed by dits for the wind speed, every so often it sends TMP and the temperature, then B and the barometric pressure.

HI Chris and all,

Some updates 30 October 2018.  I know that the two 2.0x night-only dit beacons shown on the main list are not on air anymore.  I know the gent whom put em in...

"Y" 5644 was only temp.  It is off air -- just a test for a spell of time.  The xmtr is re-crystalled on 6283 and is AM music (maybe 600-700 mW PEP AM mode for desert hiking...

New Super MedFER:

A "Tribute to INE" super-medFR is in 521.48 kHz and hrd. in 5 states so-far, incl. TX, since 2015.  It is dusk to dawn presently - 1500 mA ant. current.  33-35 watts input to an IRF-540N MosFET p.a. (class - E- switching -- highly efficient and cool running - series tuned so if the ant./loading-coil variometer is out of tune, p.a. current (DC) drops too).

It will go this DX season dusk to dawn sans outages for listening.  - MF is wonderful nowadays with exc. solar-minimum, long-haul DX reception, with Asian MW stations in well by 1200 UT (good audio 774, 972, 828, 1566, lotsa hets elsewhere)...  Since we miss INE as many's first hrd. NDB, "R" with a 5.1 second ident cycle, like an NDB, runs in the absence of 521 INE-MT now QRT.   It is also a **tribute** to the big, longtime "A" beacon of which I have met the op. and thee description of "A" 2097.3 is way cool. Now a lower-MF one to try for... the (CW) A1A mode-ERP is way-less than "A" be aware, as it is just a 23 ft. vert. with cap. umbrella and minimal ground radials/screening... 73-MB

2 suggestions about the listing of the "Rocky" beacon at 6626.4 kHz. 

  • 1. Rocky beacon might better be described as an "AM variable tone beacon" rather than a "buzzer beacon".
  • 2. The observed average center frequency of Rocky this year has been 6626.4 kHz, rather than 6626.2 kHz.

It appears that the transmitted tone modulation frequency is possibly related to temperature.
The hotter, the lower pitched the audio tone.
The colder, the higher pitched the audio tone.

When observed on a hot day in August, the frequency was 56 Hz, and it indeed sounded like a buzzer due to the lower pitch of the audio tone.

However, when observed during colder days in November, the audio tone modulation frequency was running between about 700 Hz ~ 1000 Hz, and it didn't sound at all like a buzzer, but more like a triangle wave or square wave oscillator, listen:

PLAY AUDIO 6626kHz Rocky AM tone beacon 2018NOV 2324UTC

We wonder whether the suspected temperature tone variability is intentional?

If indeed the temperature vs tone frequency is an intentional feature of this beacon, then this beacon might be described as an
Amplitude Modulated tone temperature telemetry beacon

Isn't that fascinating? :)
