Enigma 2000 Control list description

6 tones, repeating sequence. (Mazielka)
Russ selcall system for FAPSI* stations, many variants.
Uses basic tone mapping, as follows, to produce the figures 
1 - 6, giving a possible 720 unique combinations, but far fewer heard.
Usual format:-
A long single 'lead in' tone, then:-
1 = 840Hz,  2 = 870Hz,  3 = 900Hz, 
4 = 930Hz,  5 = 970Hz,  6 = 1015Hz
Observed that the X06 stations have a close, but not yet fully defined, 
association with CROWD36 stations.
(* Note that FAPSI, per se, closed in 2002 - confirmed 2003 - but the system
 is still in use by other "owners")
[Data & CW sigs sent after the tone sequence which ceased mid 2003, 
turned up again on 11 May, 2006]
Starting in Newsletter 58, page 10 (May 2010) the concept of 'Alert Signals' 
was introduced for some 'repeated scale' transmissions.
Extensive research work by the E2k 'X06' sub group has culminated in a significant
'Commentary' being published in Newsletter 62, page 7, (Jan 2011).
Those with a specific interest in the 'tone' stations should  consult.

X06 is a Russian selcal system dubbed Mazielka (Мазелка). It uses six tones believed to mean numbers, as described below:

Tone (Hz) Number
840 1
870 2
900 3
930 4
970 5
1015 6

After X06 usually follows transmission using CROWD36 data mode, which can be either on same frequency (rather rarely) or more often on other. Other times, speech communications, radio teletype, ect, have been heard after the transmissions.

This station is very hard to catch, however, it is starting to be apparent that the station runs on a very loose schedule.
