Hi I was at 369.0kHz at the time of my post. It was repeating, so I grabbed it. It's only a few seconds long but it was pretty clear.
I was scanning the band and tuned into it. I like the fact that we can record onthe fly.
Do we hve an easy way to upload a clip directly here, or does it need a host?
Cool find! S&F to the OP.
For many years I have been fascinated by Numbers Stations and have done a considerable amount of research into them, and the philosophies behind them as well. Even without knowing what they're saying, it's still a quite interesting area of research.
Here are ten interesting facts for those interested...
1. As another poster noted, the reason you can receive the signal one hour and not the next is because of the way High Frequency, or "HF", broadcast signals propagate through the atmosphere. It is for this same reason these stations are difficult if not impossible to accurately locate. The signals from these HF stations bounce ("skip") off different portions of the atmosphere so reception is not a matter of line of sight. An HF signal can be heard anywhere in the world. Sometimes, a signal originating on the other side of Earth can be heard better than one originating just 50 miles away.
2. Through the use of a 'One Time Pad' on the remote end, the same numbers can be broadcast over and over again for years, but mean something completely different each time they are broadcast. There are slight variations in the number sequences on some stations which just heighten the intrigue. If implemented correctly, the code associated with a true One Time Pad cannot be deciphered, not even by the multi-billion dollar code cracking computers of the NSA and MI-6. Each pad is different, and is never repeated (ever).
3. Numbers Stations are as much 'mind games' as they are official communications mediums, and this is part of the strategy using them. The listener has no idea how many people the number sequences are being broadcast to. It could be thousands, or none at all, but the numbers just keep on going...forever. Today the numbers could be being broadcast to 200 people, tonight just 5 people, tomorrow morning none at all and that afternoon to 3,000 people. You can't tell from just listening.
4. Numbers stations can be used to play mind games on an adversary. Let's say I start broadcasting sequences of numbers which can be heard in your country, does that mean I now have spies deployed there...or is it that I just want you to think I do?
5. Consequently, I can make my adversary spend time, resources and money on trying to figure out what I'm up to, when I might be up to nothing at all other than trying to distract my adversary...and make him spend time, resources and money. However, because I keep doing broadcasting, relentlessly, day after day, month after month and year after year I might equally be saying something really important. I might be setting up an elaborate underground network for an uprising, an attack, an assassination or a coup d'etat...and because you don't know, you can't ignore it.
6. As Numbers Stations evolved most countries employing them moved to automated voice generators. These remove any potential for unintended give aways like having a sense of urgency in your voice, etc. The numbers are just an endless string of monotone sequences of usually (5) numbers, but sometimes (4) or (3). Generally never more than (5) numbers at a time though.
7. Numbers Stations don't turn on when there's a message and then turn off when there isn't a message because this would be a dead giveaway.
8. Numbers Stations many times do broadcast other things like music and sounds (the buzzer in the OP's example etc.). More recently there are also squeeks and squawks which are clearly bursts of digital data (but for what?).
9. Strangley, most Numbers Stations are broadcast in English. There are some in other languages like Spanish and Chinese, but the vast majority are in English.
10. There are other mysterious radio stations out there which broadcast all sorts of other weird stuff like odd sounds over and over again. They have some purpose, but no one really knows for sure what that purpose is...only the originator knows the purpose and the audience. The rest of us just have to sit and wonder.
edit...BTW, there are lots of resources out there on the Interwebz where you can find out more about these mysterious radio stations. It's a very fun and intriguing thing to look into.edit on 3/19/2014 by Flyingclaydisk because: (no reason given)

Would it be possible to broadcast a broken message on more than one frequency that would then require a person tuning into those frequencies simultaneously in order to hear the actual message?
What you are describing is called "Broadband"
Yeah but a manual broadband. Like you would broadcast several sequential bits of audio on different frequencies and I would listen to all of them, collecting the information. Meanwhile, maybe you would also flood about 100 other frequencies with noise during that broadcast so I would have to know exactly which combinations of frequencies to listen to in order to even understand the message.
Just a thought. This has been going on since the 70's so I'm just trying to think of ways a pioneer in the field may have been clever. That one piece of word I got while listening is what made me think of it in the first place.
Mrs Lamar got there way ahead of you. What your talking about actually is what is called Spread-spectrum or Frequency hopping. Although you are describing a manual version of it. Most modern military radios and many civilian radios task a processor with the jumping from one frequency to another following a complex pattern to prevent simple evesdropping on a signal. Combined with encryption it's very diffcult to break. Even civilian radios using a digital signal but non-encrypted are difficult for civilians to pick up and monitor.
So... do you think that's what this is?

How, Kiev hasn't been allowed to do anything.
Of course not they the fascists in power in Kiev know whats going to happen if they try to pull something stupid.

I'm replying to you, specifically, because you have experience in this. I just tuned in to this about 5 minutes ago and only heard an intermittent buzz. Until I heard a voice. It sounded like only a part of a word, like it was cut off.
Riddle me this, Overlord: Would it be possible to broadcast a broken message on more than one frequency that would then require a person tuning into those frequencies simultaneously in order to hear the actual message? Sort of like old-school encryption or like a radio paper shredder?
