DWHI (100.3 FM), on-air Radyo Siram 100.3, is a radio station owned and operated by Hypersonic Broadcasting Center. Its studio is located along Rizal St., Brgy. Sagpon, Daraga, Albay. Its transmitter is located at Mount Bariw, Brgy. Estanza, Legazpi City.[1]

It was formerly known as Z100.3 Zagitsit News FM from its inception on October 30, 2015 to November 8, 2021, when it went off the air due to violation of some policies for provisional authority in broadcasting, which were dismissed by the management as politics.[2][3]
