M07 was run by the Czech military intelligence. Last heard on 8 November 2001.
M07 transmission began and ended with a sequence of tones resembling Morse characters for one minute. Between them:
|630||88||26||= =||65389 65389 40754 40754 ...||= =||88||26||0 0 0|
|3-figure recipient ID||2-figure number, purpose unknown||Group count||5-figure paired groups||2-figure number, purpose unknown||Group count|
|Repeated thrice||Repeated twice||Repeated twice||Repeated twice||Repeated twice|
The preamble and the outro were sent at 15 WPM, whereas the message groups were 20 WPM. Zero was sent as T - a single dash.
The format was similar to M10, and also the same frequencies were used, but M07 always carried only one message. M07 could have started at any 10-minute interval within an hour. Sometimes M10 messages were sent on M07 with the same headers.
M07's old intro and outro were reported to be rapid dashes, rather than dot/dash sequences.
