Coded numbers or letters stations.

There are lots of these examples where Hams have recorded the transmissions. Here is the time and freq for one I heard the other night: Can't make any sense out of it, of course. 0400 Eastern AM 9063khz female voice transmitting 5 letter code sequences.

  1. These coded signals have been around for ages. Our guys record them 24/7.

  2. Yeah, I remember listening to them when I got my first shortwave and wondering what they were. Matt wanted to hear them and I don't know if he has a short wave or not, so I put this you tube clip on here. Seems odd people would still fool with such antiquated communications, doesn't it?

    1. Indeed, antiquated it is, but then again the camel riders, for the most part, probably use very old equipment in their caves. There is, or was, one division within NSGA that solely worked to break the codes and they were very good at their jobs.

    2. Seems like it would be damned hard to break a code that consisted of number sequences, because there are so many variables the code writer could employ. The first digit could stand for a page in a decoding pad, for instance. But I know there are people who can do it, the Poles broke the Enigma Code. Or so said a magazine article I read, though I always thought the Brits did.

    3. It was the Brits, but they didn't break all of them. A few of the remaining have been broken with distributive computing the last several years.

  3. If I'm up that early some morning I'll tune in. :)

    1. Give it a shot. It's just repetitive sequences, but it is kind of interesting.

  4. Those are an interesting oddity of SW. Always wonder who is signalling what to whom.

    1. I have tried to find out from time to time, but there's really not much solid information on the internet about it. It would almost have to be espionage type stuff, I think the cartels use much more sophisticated communications media.

  5. I'm markbeermonster, number stations are just plain odd.
