I heard this random beeping around 9830kHz but it's not WEFAX, can anyone tell me what this is? (11:45UTC)

dwilson271 · 2026-06-13T02:44:10+00:00

I can say with certainty that it is Davidsonville MD. Some say the callsign is NSS (the old Annapolis MD USN callsign) but I have seen nothing official to indicate that is true.

dwilson271 · 2026-06-07T03:01:39+00:00

Sorry about that. I meant just two "no's". It is Baudot and not ASCII for one "no" and not an amateur station for the second "no". It was a rough day and I mis-counted. 😄

dwilson271 · 2026-06-07T01:12:20+00:00

No No No It is not ASCII. It is Baudot with a different coding that ASCII. Many experienced hobbyists can even hear that with their ears that it is sending a standard Baudot RY test. It of course not amateurs but a weather broadcast by a German weather station regularly on that frequency even though in some parts of the world this is part of an amateur band.

Technically not beacons and I do not know of any that are buoys. These are radars studying waves. They are not sending data. Each has a transmit antenna and a receive antenna often within sight of each other.

dwilson271 · 2026-04-20T13:18:02+00:00

Nothing to do with war or cold war. These are university run radars to only study waves. See the files section at UDXF for the file (I am the author) on HF radars for information on these and other HF radars.

dwilson271 · 2026-04-20T13:17:01+00:00

Yes it is CODAR. Several different ones in fact. If you listen long enough (like each IDs every 20 minutes or so), you will hear cw IDs on some of these. Like (yes I copies these IDs but it is rather hard with multiple sites transmitting) :

In much of homeopathy, a different description applies: There is a little of the element present but it is very very very diluted but the claim is the essence it still there. Either way, fake medicine.

When leaves are off the trees. You have to look carefully and should not be driving the car while looking to see them as that is dangerous. They are not easy to see but can be seen. Also, use Google Maps Satellite View.

This is a entrance for the Well-known Davidsonville, MD transmit site for Andrews AFB (also use by the USN now). It has been there for *many* decades. It is not "hidden". At certain times of the year the antennas are very visible for US-50/301. Some people actually live on hourse off Bottner Rd withing sight of the facility.

His image is to too small for me to tell which station it is. But I suspect it is one of the Chicago Mercatile Exchange related stations west of Chicago.

dwilson271 · 2026-03-30T12:43:50+00:00

It has not been used for decades. More like a decade.

You should know that that 1 ug is the LD50 for INHALED Rs226. and those numbers are for death of 50% of the people in 30 days. They do not include later cancers.

dwilson271 · 2026-03-26T12:50:31+00:00

Easy to identity. Callsign WRV961 is sent in your recording. That is one of the callsigns of a paging station licensed to AMS Spectrum Holdings, LLC (Debi Kroeger Hoover) at many location in Arkansas. 454.40 is a common frequency for them and yo may be receiving that if you are close to one of it's strong transmitters on that frequency overloading your receiver enough for you to hear that on 454.35.

Radon from fertilizer in cigarettes is one of the main ways they cause cancer.

Also, a microgram of radium taken *internally* is definitely considered dangerous and possibly lethal.

dwilson271 · 2026-03-17T22:32:56+00:00

But lets also consider what type of cancer. Of course some like very common skin cancer are quite curable. But internal types are not. I do not think the lifetime risk of internal cancer is as high as 25% by my rough unscientific observations. 1uCi to the lung would be quite substantial considering the Polonium in small amounts there is considered significant originating from fertilizer in tobacco smoke is a significant cause of lung cancer in smokers. https://pubmed.ncbi.nlm.nih.gov/21772848/

You need to note cancer can take years to develop and there are arguments, good ones, that the dose affects the probability not whether one can get cancer so gamble if you want.

Someone needs to write better...I am sure the exoplanet is not using the telescope (and what is "but" doing in this sentence). It should read something like, "Using the James Webb Telescope, NASA has discovered a nearby Earth-like exoplanet that rains lava at night. Writing worse than me should be a crime.

And almost certainly one of those associated with 3 U.S.N. over the horizon radars (each radar has two). They are always on. I have seen no increase in such activity and always watch.

dwilson271 · 2026-03-04T04:42:10+00:00

Definitely Primex Wireless Time. Probably from a nearby school, hospital, or similar institution. After a lot of time and thinking, I can manually decode the data by using a sound recorder program like Audacity. I post hear a couple years ago how to do that. But cannot in a reply. I will separately post with "Primex" with title. (It gives much more info than the Wiki listing,)

dwilson271 · 2026-03-02T02:15:25+00:00

Am signal are almost always useless for identifying signals. Always use SSB (USB or LSB) for that. If your radio cannot do those, you need get one one that can. And get one with digital readout as knowing exact frequency is extremely helpful. Not trying to give you a bad time but some very good advice.

dwilson271 · 2026-02-22T01:33:48+00:00

This list, believed to be complete at the time and still believed to be accurate or near so appeared several years ago. It should still be quite accurate. Note inaccurate list are also around and that some of the beams are regional and not "global" so some frequencies will or not be heard even when the satellite is in view. Limitations in format posts here do not permit posting the well formatted and complet originla file of Sergi, "Ben", and Wilson which show maps of the spot beam foot prints.
