S06s follows the same transmission format as the Russian GRU station S06, possibly it runs on equipment donated by that agency. However, its operation habits are radically different from S06.
S06s has a specific protocol for its messages. It sends the same message for the first two weeks of the month, then changes to another one for the next two weeks. On the fifth week, only null messages are ever sent, though repeats of messages from the previous weeks have been noted, presumably as a mistake. The messages itself are believed to be composed out of instructions from a code book, as the same groups and strings are seen very frequently in messages spanning several years, sometimes even with only one digit changed. In valid messages, the first digits of each transmission before the message (the ID, the 3-figure group, the amount of groups) are always unique. In valid messages, the 3-figure group only starts with either 2, 4, 5, 8 or 9. Most of the messages are 5 to 9 groups long, rarely 10 and even more.
S06s runs on schedules with two sendings each, the second always follows 10 minutes after the transmission (the sole exception is ID 374 on Tuesday, which repeats 15 minutes later). The repeat frequency is either higher or lower. The frequencies are usually changed seasonally - one frequency is used from November to February, another from May to August, and yet another for the remaining months - though some schedules with the same frequencies all year round are being noted. The frequencies are normally reused on a yearly basis, but sometimes they are changed.
The S06s transmissions usually start a few seconds early or a few seconds late, and this changes over time due to lack of synchronization with the time reference. S06s has two main transmitters, which differ by the way the lower sideband is suppressed. On the first, the LSB is heavily suppressed, but can still be noticed if the signal is strong enough. The other one has only about -10 dB suppression. S06s also has a third transmitter, with perfect A3E modulation, which is used for backup only. The audio is usually heavily overmodulated. On 3 November 2014, S06s was heard in LSB + carrier mode with suppressed USB using the second transmitter.
S06s runs off a computer running Windows XP, as on Friday, 10 October 2014, S06s was followed by the Windows XP USB disconnect sound.
S06s started in May 2004. S06s at the time was reportedly using the same male voice as S06, but it also had a female voice, which was provided by the same person who also voiced the sister station E17z.
Up until July 2004, S06s repeated one message for the entire month, then it was changed to send messages only for the first two weeks of the month, then null messages afterwards, but has later reverted to the previous behavior.
The current voice started in October 2005.
In May 2009, the current message protocol started.
