History
In the 1990s, S25 had a daily schedule at 08:00 UTC. The station broadcast on 14890 kHz during 08:00-08:20, and then on 11270 kHz during 08:20-08:40. Each broadcast had four sections instead of two, were 10 minutes long instead of 4, and ended "615 615 615 000" instead of "00000 00000." The 3-digit ID was always "615." In 1998, this schedule changed from daily to Monday only, and then disappeared completely in 1999.
In September 2004, S25 was revived using the current format. It is now mostly unscheduled and heard at random times. However, between at least 2014 and December 2017, there was a regular schedule using the ID 104.
