S02 was a numbers station that had rare broadcasts and at one point was sent on a “date of the month” schedule. It used to send messages on the 9th of every month at 19:30 UTC on 4740 or 4740 kHz in 1994. Even during its highest activity of traffic between January 1989 and March 1990 it was rarely heard.
The numbers were read in Bulgarian and it played the intro music “Il Silenzio” by Nino Rossi an hour before the transmission. The station used to have a male voice at one point but also used a woman’s voice. This station has not been heard since 1996.

This variant played “Taps/Il silencio”, which was the same tune that was given the Enigma ID X01 – The Bugle.
S02c is an S02 broadcast with a 3 digit Noma / Nomer that is then reversed.
S02d was a variant that sent a 5 digit Noma / Nomer.
