6832khz

I am very new to amateur radio and am messing around with the websdr here :

http://websdr.ewi.utwente.nl:8903/

I heard the end of a number station broadcast on 6832khz at about 16:15 GMT, very clearly, English, male voice, reading out 5 figure groups of numbers, ending in zero zero zero, zero zero zero. I only heard about 10 seconds of it then it finished.

How can you tell that it is not amateurs messing around?

Has anyone else heard this? Will continue to monitor.

Just after hearing my first number station, found another - and after scrambling around a bit, managed to record some of it on my phone (hence the sound of me typing in the background). Found at 6923kHz recorded on 17:15 GMT

After a bit of googling, I found out that this is the Polish number station E11A.

Various conspiracy theories abound as to why these numbers stations (as they are known) exist, but the most accepted one is that these transmissions are for folks with portable sw receivers and one time pads that decode to messages for spooks. These folks are sometimes reported arrested and they mention the fact that they had a 'SW Radio' and a 'pad full of numbers' in the lay press.

There's a whole sub culture of folks that study and map this stuff. Many countries do this - particularly the British, Cubans, Isrealis and many more

Yes, I read all about them - quite happy now I've actually heard and recorded one now, albeit through websdr rather than a radio..
