The Enigma 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 in [[Crowd 36]] or similar.

Up to 99% of these signals are sent out at random times on up to 350 different frequencies.
These signals take the form of a repeated series of 6 tones (at 840,870,900,930,970,1015 hertz) sent in 2 seconds, and in any sequence of 1-6, producing 720 variants.

These signals are largely transmitted in AM but are, generally, easier to receive in USB. Each transmission usually lasts for around 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 signals.

You can 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 tone) 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".
A sound file of 164532 can be found at [[File:164532.mp3]] and a Spectral Image is available to the right on this page. [[Image: 164532.jpg|thumb|300px|right]]

X06 signals are widely heard in Europe and the Mediterranean area, and also regularly reach Argentina and occasionally Australia.
