Currently they are on air for the morning transmission only on 4895 at 0055-0400 (Sat Sun 0430).
After about 10 days they will be on in the evening hours also on 4895 at 1130-1700 (Sat, Sun 1741)
After about 20 days they will be on the daytime frequency of 7230 at 0620-1030
The transmitter is of 50 kW but it is being operated now at 30 kW
