High Pitch Polytone (ENIGMA XPH)
This is a copy of The Numbers Racket CD-ROM, which I prepared back in 1998. I am presenting it here, unedited, for historical purposes. Obviously most if not all of the information is 'out of date' today, but think of it as a snapshot of what the Spy Numbers scene was like in the late 1990s.
Like what you see here? Help support my work by taking a look at my software , and buy something of interest :) It's all available for download before purchase, so you can try it out.
Enjoy!
The carrier generally appears on the frequency about five minutes before the start of the transmission. Each transmission lasts about three minutes, the short length makes the station rather elusive.
The following schedule has been reported:
0600 9394 0620 11494 0640 13394The station appears to follow a monthly schedule.
The call-up appears to be four tones repeated (identification?), followed by two tones (group count?), then into tone groups.
The call-up tones are 1 second long each.
There is then 2.5 seconds of a warbling tone, indicating that the message is about to begin.
This is followed by 10 pulses, each 133 milliseconds apart. This appears to be for timing purposes, to get the receiving equipment synchronized with the data about to be sent.
Then the data is sent, each tone is 133 milliseconds.
