Congress Radio was a clandestine and underground radio station, which operated for about three months during the Quit India Movement of 1942, a movement launched by Gandhi against the British Raj for independence of India. Congress Radio was the broadcasting mouthpiece of the Indian National Congress, and functioned from different locations from Bombay, currently known as Mumbai. It was organized by Usha Mehta (1920–2000), a veteran freedom fighter of India with the help of ham radio operators.
