Along with Libia Lobo Sardesai, whom he later married, he ran an underground radio station, Voice of Freedom, that transmitted across Portuguese Goa from 1955 to 1961, advocating the cause of the Goan independence movement.

Vaman Balkrishna Naique Prataprau Sardesai was born to Bhalchandra Desai on 5 May 1923 in the village of Vadi, Ponda taluka, Goa.

There, he worked with Ravindra Kelekar to publish Konkani language poems in their fortnightly publication Meerg, writing under the pseudonym of "Abhijeet".

Sardesai, Libia Lobo and Nicolau Menezes, a Goan freedom fighter who had been living in hiding in Bombay, came together to form a team.

This grew to be the Voice of Freedom radio station, through which Sardesai, Lobo and Menezes would transmit news and important information to Goans.

On December 17, 1961, the station transmitted a direct message from then Defence Minister of India, V. K. Krishna Menon, requesting the Portuguese Governor General to surrender.

[4] Sardesai was among the first three senior officers from Goa to join the Indian Administrative Service and was given significant responsibilities, serving as director of various departments such as Industries, Information, Sales Tax Commissionerate, and District Collector.
