X06 Logging Week 21st to 28th March 2011 The Enigma2000 X06 Team are looking to Spooks members for some help in a concentrated Logging Week for 7 days commencing Monday 21st March 2011. We hope that you will join us in trying to track down more of these elusive signals, both those on known and unknown frequencies. A little background may help. The Enigma2000 designator for the Mazielka series is X06. Mazielka is thought to be a selcall system used by the Russian MFA to alert out-stations, in advance, of forthcoming messages to be sent out in Crowd 36 or similar. Up to 95% of these signals are sent out at random times on up to 350 different frequencies. The signals take the form of a repeated series of 6 tones (at 840, 870, 900, 930, 970, and 1015 Herz) sent in under 2 seconds and in any sequence, producing 720 variants. The signals are usually transmitted in AM but are, generally easier to spot in USB. Each transmission usually last 4/5 minutes Apart from the 720 variants, there are other Mazielka tone combinations of simple 2, 3, 4 and 5 tones which you may hear and, of course, the frequency list covers only those frequencies where we have already logged transmissions. You can also expect to find Mazielka signals all the way from around 4 MHz up to 25 MHz but their random nature makes them difficult to pinpoint Identifying a Mazielka signal is simply a matter of reading the tones in order. For example 840 Hz (lowest tones) is designated as "1", 870 Hz as "2", 900 Hz as "3", 930 Hz as "4", 970 Hz as "5", and 1015 Hz (the highest) as "6". Chris Smolinski has kindly provided a Wiki page at <http://www.hfunderground.com/wiki/X06> http://www.hfunderground.com/wiki/X06 and this provides information you will need such as a typical example of the Mazielka tone sequence 164532, at <http://www.hfunderground.com/wiki/File:164532.mp3> http://www.hfunderground.com/wiki/File:164532.mp3 and a spectral image at <http://www.hfunderground.com/wiki/File:164532.jpg> http://www.hfunderground.com/wiki/File:164532.jpg Also on the Wiki page is a list of the currently known frequencies. X06 signals are widely heard in Europe and the Mediterranean area and also regularly reach Argentina and occasionally the United States and Australia. If you could spend some time in the Logging Week or indeed at any time, searching for these signals we would be grateful for your help. Please post any logs to either p <mailto:pe...@bmsona.co.uk> e...@bmsona.co.uk or <mailto:jochen.schup...@gmx.de> jochen.schup...@gmx.de Please include date, time logged, frequency, tone sequence (if possible), your location and a short sound file. It would also be useful in terms of the whole exercise if you could estimate roughly how much time you spent on the project. Many thanks for your help and good luck with your logging!! ______________________________________________________________ Spooks mailing list Home: http://mailman.qth.net/mailman/listinfo/spooks Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Spooks@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
