"DO NOT ANSWER": 5 Mysterious Radio Signals and Numbers Stations

In 2012, a number of radio listeners in America heard a mysterious transmission that would prove, as investigations unfolded over the following years, to have wide-reaching geopolitical implications.
The frequency usually broadcasts nothing but static silence. However, on this occasion, and at intervals thereafter, a masked voice was heard. The voice was that of a woman, robotically distorted, reading seemingly random numbers in Spanish.
This was followed by a number of digital tones…
… which then faded away. The recorded message came in waves, repeating strings of digits, for about 20 minutes before they ceased and were replaced by the crackle of yet more static.
The most popular explanation for the signal is that a government agency was distributing coded messages to spies. Spies with the key to decrypt the messages would receive their orders by listening in and deciphering the patterns of numbers.
Investigations found that the signal was being broadcast by a station codenamed HM01, which is indeed owned by a Cuban intelligence agency. However, it remained unclear what the messages meant or for whom they were intended...

⁠@@heroscapewarrior4217Spies and saboteurs going back to WW1 are at times given something called a “one time pad.” The pad is essentially a key to decrypt messages being sent as “random” number sequences by the station. The coded messages being sent are theoretically unbreakable because the key (the one time pad) is a completely random pattern, it can only be used once, the message and key are always the same length and only the sender/receiver have copies of the key itself.

When I was in US Army Signal Corps, an instructor told us that these stations weren't broadcasting any real data...the strange sounds and other audible features were a means for the station to authenticate itself. "The real message comes the day the station goes dark and stays dark." The exact time and date would correspond to a 'code book' entry informing agents what to do next.

[@jaket2k927]

I suggest starting cheap and affordable for radios and scanners as a hobbyist myself. You need UHF, VHF, ULF, SW, to pick up generally everything. But here's the catch. You have to understand the environment you're in too and be familiar with interferences. Like your car for example has a "Filter" on the alternator because you could hear it on older radios. My Grundig 750 picks up machinery and equipment. Case in point one DXing session I had I was scanning and the deck depot on my ship turned the lights on, the electronic noise sounded like a screaming parrot. My chief laughed as I got up swearing like crazy and rubbing my ears. So here's what I have picked up. Alaska (At sea): CNR-1, Public radio in St.Petersberg Florida, Brother Stair (He's a meme for being hellfire and brimstone) VOA in French. BC (at sea): CNR-1, BBC Australia. Washington State (land): CNR-1 Radio Havana, Radio Havana English, NHK, Radio Pyangyang (Korean) Oregon (Land): Art Bell Coast to Coast FM, Pirate Station ran by White Supremacist, South Asian Music. California (at sea): Jungle Public Radio Brazil, CNR-1, couple HAM stations. The thing is that this is very limited with lots of electronic noise or bad locations. But I encourage you to hit up the DXing (that's the hobby is called) forums and learn more. It's pretty cool and fun. I got started DXing SW when I was in trade school and remembered Oregon has a ton of little weird radio stations.

In the 70s I would play my electric guitar through a pedal and this stuff came through my amplifier late at night. I would call my band mate and have him listen through the telephone. I think either the pedal or the pickup acted like a sort of antenae. We figured that it was some kind of spy stuff. Jeff Tweedy named his album Yankee Hotel Foxtrot after these Irdials that he picked up. The album The Conet Project collected a bunch of these Irdials.

[@oldschooljack3479]

Worked with a guy who had been in a branch of the US armed forces... Army or Air Force, don't really remember as It's been 7 years ago... Anyway, we were working in Illinois and he knew I was from Oklahoma. He asked if I had ever heard of a particular small town. I had heard if it and had actually been there. He told me that he and a handful of members of his unit had been sent there to set up a listening post. Said they were there for a few weeks listening to radio traffic from another country... North Korea, China, someplace like that... Again, I don't remember. But something about that area around that little town allowed them to receive a good enough signal to monitor comms from somewhere across the world. Pretty wild stuff. I'll have to see if I can get ahold of that guy and fill in the details of my foggy memory.

[@janemiettinen5176]

You woke up distant memory in me. Im a Finn from Helsinki, Estonia and Tallinn is situated right behind Baltic on the South, pretty much just like you and France. My grandpa worked his whole life in radio (Yleisradio, our BBC) as technician or mechanic in the link tower, and loved both tv & radio deeply, in all forms. He had the first Beta-video I ever saw, later he bought VHS too and used both daily. He set his tv to catch Soviet era Estonian tv, he even learned some Estonian from it, but he also tinkered with radios. This is very faint memory, I must’ve been really small (prob 1980ish), but Im sure he phoned to one of his radio enthusiast buddies and said he heard something weird, coming from Estonia. There was a sense of urgency or discovery, unusual or weird things were going on. I wanna say he gave the “coordinates” (frequency?, no idea what they are called) over phone and told the other guy to check it out, almost like “can you hear it too?”, but this part Im not as sure. I only remember sitting on the kitchen floor with my puzzle and the slight worry, surprise or excitement in his voice. What a weird, long buried memory decided to surface, thanks to your post! Now Im left wondering was he just really super into all things transmitting or was my mild mannered and stoic gramps possibly a spy :)

“Skyking” is the callsign for all SIOP (Single Integrated Operations Plan) assets which includes nuclear capable bombers, missile silos, communications aircraft (e.g. E-6 Mercury and E-4 Nightwatch), and support aircraft and crews. These take higher priority over EAMs and Force Direction Messages. Because EAMs and FDMs cannot be decoded without the key, it’s impossible to determine if a message is an EAM or FDM. It’s also impossible to know if the encoded message is gibberish just meant to throw off hostile nations who might be listening all the way to a true nuclear launch order.

[@mycroftsanchez901]

Would be useful to have the frequency of each of these channels listed and mode of transmission (AM, FM, USB, LSB etc). Regarding the 'zombie' satelites as a radio ham we had one of our OSCAR satelites come back to life a few years ago but only whilst the solar panels were in sunlight so we realised the onboard batteries had gone open circuit and it was operating only by solar power as are the others.

[@kilodeltaeight]

AO-7 is my personal favorite zombie satellite, not least of all because of how we got it back: after it failed in the early 80s, Polish resistance fighters discovered it would sometimes work in sunlight, and used it to communicate with different cells across communist Poland and the west. Given that the government had seized most radio gear, and monitored everything, AO-7 was one of the only ways to freely communicate. After the fall of the USSR, some resistance fighters wrote about it in their memoirs, and it was largely forgotten - until a ham read them in 2002, realized the implications, and did some tests to determine that it still worked! AMSAT made an announcement, and to this day it’s one of the oldest working satellites up there.

There was a rumor as far back as the late 90s that amateur enthusiasts were actively seeking to use some of the older, barely functional communications satellites like the old Inmarsat (British) and a few others for long range amateur communications. It was also speculated that the "zombie satellites" are often tapped for their functioning components as stages for test signals and other non secure communications. Also as emergency backups for satellites with failing X and Ku band transmitters. This is usually older satellite communications, as more modern satellites and antennas receive the stronger S Band. Also, there are a few zombie Iridium Satellites that Motorola lost communications with that are "spewing" as well.
