History
Radio 1 was launched on July 3, 1939, as Radio Toralaq Domestic Service, which was meant to serve the locals. The station only broadcast for 3 hours and was only available in Tottomic. In 1941, Radio 1 fell under the umbrella of Toralaq Broadcasting Corporation. It started broadcasting on FM radio in 1948, and its transmitters were moved to newly constructed Feederet.

In 1950, Radio Toralaq Domestic Service was renamed to Radio Feederet Local Service. After the communist takeover in 1956, the station was renamed to Local Voice of the Communist Party of the Toralaqian Socialist People's Republic, part of the renamed Voice of the Communist Party of the Toralaqian Socialist People's Republic. It was reverted back in 1968 because the name was too long to be memorized.

In 1979, with the launch of Radio Toralaq Secondary Domestic Service, the station was renamed to Radio Toralaq Primary Domestic Service. It started to focus on mostly educational and current affairs programming, meanwhile, the Secondary Domestic Service aired music.

In 1999, Primary Domestic Service fell into the ownership of Voice of YinYangia, renaming it to Voice of YinYangia Primary Domestic Service. It mostly simulcasted with the international service.
