In 1995, S02 had one schedule - 9th of each month at 19:30 UTC during DST in CET timezone, and at 20:30 UTC otherwise, on 4740 kHz[1]. An hour before the transmission, the first few bars of "Il Silenzio" would have been played; this was dubbed "the Bugle", or by the ENIGMA designator "X01" (initially "S02b"). On the variant S02a, however, it would have been played right before the transmission.
