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 Obviously most if not all of the information is 'out of date' today, but think of it as a snapshot of what the Spy Numbers scene was like in the late 1990s.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!


Morse Station M1

Morse Station M1

M1 is hand sent in the A network and the messages have a usual group count of 40 groups. The last group is now always the date the message was compiled and the group count minus one. For example a message of 40 groups compiled on the 10th of the month, the last group would be 10039. This also applies to the M1 B network.

Type of transmission is MCW using low modulation of 2 audio tones. Sent at about 17 WPM although this can vary depending on the operator

Reference   Call     Preamble           Message          Ending
 M1        197 R4   381 381 40 40 = =    40x5F   = = 381 381 40 40 000
The IDs for this group remain the same for the following months.
197 November December January February
463 March April September October
025 May June July August

Variants of M1 M1A End of Month transmissions, the last Thursday and Saturday of each Month These transmissions are an entirely different format to the normal M1 but they can vary each time. Suggest listening to them to hear the format.

M1 B Network. These are sent to individual IDs and the frequencies are changed at intervals so cannot be listed. These messages are repeated and can be the same for four weeks or more. Parallel frequencies are used, group counts vary between the low twenties and as high as seventy five. Transmissions are hand sent. Note that the last group is the date the message was compiled and the group count minus one. Unlike M1 this station repeats the same message for several weeks. This is the sister station to S21.

M1C A common format of these is listed. Several other formats exist.If a message is sent it is nearly always 10 groups.

385 385 385 84297 84297  Repeated 8 times
30 Second pause
385 385 385 86652 86652  Repeated 8 times
Can be any number of these, usually machine sent, ending is hand sent.
385 385 385 000
These can be on at any time and do not use the normal M1 frequencies so are very difficult to find.
