Numbers Stations

Postby Assassin of Silence » Sat Sep 09, 2017 8:53 pm

Got chatting to a guy yesterday who mentioned numbers stations. I wasn't sure what he meant but since looking into it I really am intrigued. As a newcomer to scanning I don't really know where to start searching for them. I'm using a 75xlt with a R881 antenna. Do I need anything else / better than my current set up ? What frequencies should I target ?

I'd love to know more about these transmissions so I'd welcome any stories, help, tips etc

Many thanks in advance for your advice folks, much appreciated.

A snag here - numbers stations are all on HF - so you really need a different radio and antenna system - sorry about that. Most are SSB or AM.
Have a look at these that have been collected over the years.

You will see they are LSB, USB (which depends on frequency) AM and even Morse Code. They use different bands because the way HF works is that things bounce of the ionosphere and there is a frequency limit which changes continuously, and going above it means transmission go through, off into space, and below it they reflect back down. A band that works at 10 in the morning can be useless in the evening and vice versa. Even more confusingly, the paths from A to B might work, but C to D won't. Hence why HF is kind of magic. Antenna wise, probably a long wire down the garden will work, and a radio capable of tuning between 1.6MHz and 30MHz at the top.

The numbers, of course are meaningless, but there's a branch of our hobby who search out new ones - mainly because as you have discovered, it's the probably communication method of getting signals and messages to people somewhere in the world secretly, in a way unlikely to leave evidence. It's been the subject of a pretty dire movie - where the facts were twisted quite a bit, but the sound of them is very spooky. I first came across them during the cold war, when their significance was extremely worrying.

Your radio, sadly, just isn't the right thing to listen to this stuff on at all - sorry about that!

Thanks for your reply, much appreciated. I really wasn't sure about my scanner which is why I was asking.

It's certainly an intriguing subject and one I'd like to explore further. Can you recommend a radio to look out for that would serve the purpose ? Ive discovered that a couple of meters of speaker cable would make an adequate aerial but not sure about the actual receiver.

Try the online receiver at University of Twente in the Netherlands. It's free to use & will allow you to listen to what ever you want.

Yeah, that's what I'm using now. It works really well.

http://priyom.org/ Is a useful site too. It lists the times and the frequencies of the next numbers stations broadcasts too. Some interesting info there aswell.

Fascinating....
