Usha Mehta, Freedom Fighter against British Rule in India At 22, she helped establish the underground station Congress Radio, which amplified Mahatma Gandhi's message of rebellion. - By Geneva Abdul When Mahatma Gandhi gave his famous "Do or Die" speech on August 8, 1942, galvanizing Indians to demand the end of British rule, Usha Mehta heeded the call. With the help of other activists, Mehta, who was 22 at the time, secured a ghost transmitter and started an underground radio station to amplify Gandhi's message. "When the press is gagged and all news banned, a transmitter certainly helps a good deal in furnishing the public with the facts of the happenings and in spreading the message of rebellion," Mehta recalled in a 1969 interview.
