Known counterpart stations M10

S10d was ran by Czech Military Intelligence (Czech: Vojenské zpravodajství). Active from 1996 to June 20th, 2007.

Like its predecessors  S10 and S10b, S10d often sent more than one message in one transmission to more than one recipient. In that case, in the intro, the ID's and the group counts were included for all the messages, in the same way as the first one. Then the preamble, the message and the outro except "Konec, konec" followed for each message. The last message ended the transmission with "Konec, konec".

From 1996 to 2006, the arbitrary ID was only 555. Then from 2006 until the station's demise random triplets were used, but not 555 anymore.

S10d could have been heard daily, but it had way smaller amount of schedules than M10. S10d could have started at any 5-minute interval within an hour, and was usually, but not always, transmitted on two frequencies in parallel. S10d's schedules were mostly in the morning, afternoon and the evening. The messages were usually repeated later in the same week at the same times and on the same frequencies.
