[Spooks] NOT X06!

[Jochen Schäfer]

Hello J. Murphy et al,

the station you heard is definitely NOT X06, although it sounds similar - 
that's trou. But X06 has breaks after the 6 tone scale, which repeats over 
and over. This station is a kind of Polytone, which uses a similar system 
like X06, but the tones are changing more often. But if you listen to usual 
X06 recordings, you'll notice the breaks and a repeat of the scale till the 
end of transmission. There are also X06 variants, which have less than 6 
tones (X06b) or 3 x 2 = 6 tones like "121212" (this is X06a) or the 6-note 
rising scale (X06c). Most X06 transmissions have scales from 6 different 
tones. We describe them with "1" as lowest and "6" as highest tone, for 
example "463125", one of the most frequently used scales of X06.

Best 73
