S17c was run by Czech Military Intelligence (Czech: Vojenské zpravodajství). Last heard on June 19th, 2007.

Transmission format:

Intro Preamble Message Outro
555 313 05 313 42 05 Pozor, Pozor 52027 Pozor, Pozor 42 05 Konec, Konec
3-figure arbitrary ID             Single 5-figure group, middle digit always "0"        
Repeated thrice Repeated thrice   Repeated thrice Repeated twice Repeated twice   Repeated 10 times   Repeated twice Repeated twice  

The general format was the same as S10d, but the recipient ID, the 2-figure number in the preamble and the amount of groups were constants.

S17c was sent out daily at 12:50 UTC, and each transmission lasted about 7 minutes. Up until February 1st, 2007, it was transmitted on two frequencies simultaneously, and only one frequency afterwards. Until February 2nd, 2007, the arbitrary ID was only 555 - then until the station's demise random triplets were used, but not 555 anymore.
