Howard Barnett has asked me for information on Radio Belarus' schedule and programmes. They use just the two shortwave frequencies for all of their language services. The transmitter switches in at 1100 UTC and runs through to 2300 UTC on 11730kHz, while 6155kHz is on from 1705 and also stays on air until 2300 UTC. English is from 2100-2200 (from 2020 UTC at weekends). My favourite programme is probably Music box, which plays a mix of modern and folk music every Monday. Postcard from Belarus is an interesting historical and tourism programme and Unlimited Nature explores the wildlife and countryside.
Schedules change 31 March.
