Radio Sultanate of Oman began broadcasting on a 1KW transmitter on 30th July 1970, just one week after HM Sultan Qaboos bin Said came to power, from a small station at Bait al Falaj in Ruwi, near Muscat. In the following year, transmissions began from Salalah.

In 1972, a new medium wave station was inaugurated and in 1979, the Muscat and Salalah stations were linked by satellite. The number of Arabic transmission hours increased from four hour per day in 1970 to round-the-clock transmission from 1 November 1998.

The transmission frequencies are 1242 kHz from the Muscat station and 738 kHz from Salalah, while the relay station in Haima transmits on 576 kHz medium wave. Arabic programmes are broadcast via Radio Sultanate of Oman's own channel on the Arabsat satellite, Egyptian Nilesat, and to Hot Bird 4 satellite as well as via the internet.

English FM programmes are broadcast 15 hours each day on frequencies 90.4 MHz from Muscat and Salalah, and 91.3 MHz from Thumrait.

In April 1999, the FM English language programmes began broadcasting via Arabsat 2 satellite, located at 26 Deg East. These programmes may be heard through receiver setting frequency 4140 MHz, audio frequency 7.74 MHz, analogue reception system.
