On 2 February 1962, National Liberation Front of South Vietnam set up Liberation Radio (Đài Phát thanh Giải phóng) in South-controlled territory, and conducted its first airing with the title "This is Liberation Radio, the voice of the National Front for the Liberation of South Vietnam".
Due to the fierce war effort, Liberation Radio was relocated around several provinces before being stationed in Hanoi, and was operating under the aliases of "Viz 1080 Ministry of General Staff", "C55" and "CP90".[2] For the duration of the war, this station maintained broadcasting for 10 hours a day in 5 languages: Vietnamese, French, English, Chinese and Khmer.[3]
