A in depth look at the mysterious XP polytone station and other Polytones

Below you will find some mystery sound files, the most recent is at the top.

Well its been a while since I added a 'sounder' type file and strictly speaking this is actualy a numbers station! Its our old numbers buddies in Cuba! we have become accustomed to V02a and M08 the Spanish lady and cut numbers cw stations, but in 2007 they started with a new mode BPSK-31 to be exact. If you use a decoder on this file you will see numbers and then between the messages 22222 is used to mark the end and 11111 to mark the start of the next message. The action took place on 17478 at 16:00 to 16:50 13/03/2007. Click the cigar to hear or download and click here for a picture of the decode.

Not content with passing a rare message S28 is obviously getting bored with just buzzing away day after day! so for a bit of variety it decided tonight to change its sound at 2 mins to each hour! This recording was made at 22:58 you hear the buzz, buzz change to a sort of rising and falling alarm then at 22:59 its back to the old buzz, buzz. I noted this at 21:58 as well! 16/03/2006 (update May 2006 S28 now sends this on the hour)

S28, XB, The Buzzer or Station UVB76 located in Povarovo to the north west of Moscow on 4625 is well known! However less well known is the fact that it sometimes sends voice traffic! This rare event was monitored by us at 07:57 on Tuesday 21st Feb 2006. A translations is: 75 59 75 59 <> 39 52 53 58 <> 5 5 2 5 <> <> <> <> konstantin

This is XPA the new polytone on the block! it replaced XP around November 2005. See our polytone page for more detail. This one recorded at 07:20 on 10648 AM Friday 27th Jan 2006.

27/09/2005 Tuesday from 19:08 we found what has come to be known as 'The Whale' or 'Backwards music station' this one was on 4742 USB and the clip has the added bonus of RAF Ascot 6819 calling Architect he gets no reply! This was a big signal here and sounds very much like feedback, so is it a jammer or just a open mic? The Enigma designator for this station is XM.

Well its the first of the month and here we go with another spooky sound clip to add to our collection!

This one was found on 01/07/2005 on 10305 AM, it was a very wide AM signal with a metallic quality to it, it reminds me of 'The racing car' link 11 sound that you can find further down this list. Or maybe its another rada system?

The recording starts off with the AM signal recorded just after 18:57, when we checked later at 21:16 the sound had changed. Can anyone tell us what it is?

Great, we found out what this is! its a Russian MS5 12 channel modem in idle mode, then switching to traffic. (Thanks to Japan UTE Monitor from the Wun list)

We found this today 25/05/2005 at 22:20 on 11426 LSB, at first we thought it may be a Polytone station like XP. It would be good to get a positive ID on it to save confusion later. Click this blue dot to see a picture. Good news! our friend Leif from the Spooks list tells us what this is.. "Its Algiers Ministry of Foreign Affairs using Coquelet-8 at 13.33 Bd; traffic is in French"

A recent strange noise find! six tones arranged in a definite pattern found on 15829khz at 20:10 on 23/05/2005. The sound clip starts off in narrow AM then switches to LSB CW mode. Click this blue dot to see a small spectrogram of the sounds. Great! we know what this is now, Thanks Richard. This is X06 Mazielka, a Russian selcall system.

What is this strange little sound, probably some sort of digital system, can anyone help?

This sounds like a very bubbly tummy! however some freinds from the WUN list pointed out that it is in fact a "Over the horizon radar transmitter. Bandwidth is about 20 kilohertz and it transmits 25 hertz spaced carriers in
burst of 40 milliseconds This one can be heard all over the HF spectrum and is thought to be
transmitting from Spain" recorded 31/03/05 on 18000khz at 10:30

We found this today 10/03/2005 on 13237 USB from 20:50 onwards, it sounds like a racing car changing up through its gears!
