Numbers station - XPH High-Pitched Polytone?

Caught around 6.83 Mhz (1945 UTC - 7/2/08) - I was trying to receive using 2 AM radios to simulate SSB, although I'm not sure if this was an SSB broadcast.

Missed the preamble, although the ending sounds like the XPH polytone I've heard on the Conet Project.

XPH is classed as a numbers station (i.e. the tones can each be a 'number'), and is as mysterious as it is fascinating. XPH is believed to be Russian in origin.

For those who are confused as to what a numbers station is, see http://en.wikipedia.org/wiki/Numbers_station

UPDATE: I have been informed that XPH is no longer (very) active, so this may be one of the 'other' XP stations, e.g. XPA. Bear in mind, all these classifications are from monitoring groups rather than being anything official.

what you picked up was a cell phone looking for a nearby tower. On a tv it sounds like a static d d d d d and it occurs at the freq. of 6.2 - 7.0 mhz ISM 6.78 ± .015 MHz

I'm afraid not. I would worry if phones worked this slowly.

If you disagree, please record this 'cell phone phenomenon' on your tv or radio and upload it. I look forward to this.

I got that program and it decoded the tone into numbers quite easily. Things like this interest me very much and I really want to find out more about it.

[LCduT]

There's a Yahoo group called Enigma2000 who specialise at looking into this. It's all very involved, but if you are interested it's currently the most established group of like-minded individuals.

Is it possible to decode?

[LCduT]

If you are the recipient, very easy :-)

There's also a program somewhere online to turn these into numbers, although that's not the same as 'decoding' the message.

@Letsgoherd3008 These were on the air, long, long before cell phones.

@4405486 Agreed, The brits always have the fun with shortwave stations.

@matkovicha im sure if you had the proper codec you could break a number station code. you could transmit the same code 2 days ina row each day the same code could be something completely different without the codec theres a chance you will never crack it

thats probally what techno is going to sound like in another 20 years
