For many, radios evoke deep nostalgia—once the lifeline of music and stories in Indian homes. In Kolkata, 66-year-old Amit Ranjan Karmakar, the 'Radioman of Kolkata,' preserves this legacy. His shop in Kumartuli houses more than 200 vintage radios, revived each Mahalaya to echo tradition. Amid streaming's rise, Karmakar keeps the heart of radio culture alive.
