Rádio Muda, Radio station at University of Campinas, Brazil.

Rádio Muda is a student-run radio station based on the University of Campinas campus, broadcasting through FM frequency and online platforms. The station features diverse programming including music, cultural shows, and student-produced content throughout the day.

Rádio Muda has broadcast for over 30 years from inside the water tower of the State University of Campinas (Unicamp). Its origins are passed down orally between programmers: engineering students who built the transmitter, early transmissions at the Taba, and the theft of the transmitter during a DCE election are told in conflicting versions. A collective makes the decisions, and the station's structure changes with each new intake of programmers.

The station serves as a platform where local musicians share their work while students gain hands-on experience producing and hosting shows. This role connects university life with the surrounding community through shared programming.

You can tune in through the local FM frequency in the Campinas area or access streams online from anywhere with internet. Reception works best when you are near the campus or when streaming through a reliable internet connection.

Rádio Muda broadcasts at 88.5 MHz, a frequency far from the 118–136 MHz aircraft band, so it cannot interfere with aviation. Its transmitter uses a low-pass harmonic filter with rejection above 40 dB, verified by Unicamp electrical engineers with a spectrum analyzer.
