The first university radio station in Bulgaria, ALMA MATER, was established on June 15, 1993, at the Faculty of Journalism and Mass Communication of Sofia University. In 1998, it began broadcasting on 87.7 MHz, and after 2001, on 88.0 MHz.

Sofia University "St. Kliment Ohridski is a public media service provider and holds Individual License No. 1-062-01 for the provision of radio services. It began broadcasting on January 11, 2001, with local coverage in Sofia on FM frequency 88.0 MHz. The Radio Alma Mater program has a multi-thematic profile.

Radio Alma Mater has a multi-thematic profile. Here, students have the opportunity for professional development. The radio is a place for free expression of opinion, critical thinking, and creativity. The program is diverse in terms of topics and genres.

The conceptual idea behind the programme development is for the radio station to be an alternative to the existing multi-thematic radio programmes in Sofia, not only because it is public, but also because it is the radio station of Sofia University St. Kliment Ohridski.

Most of the radio programs broadcast in Sofia are aimed at the mass audience, neglecting the interests of intelligent young people in our country. The programs on Radio Alma Mater are geared towards their lives, interests, and hopes.

The musical concept of Radio Alma Mater emphasizes new Bulgarian music, as well as hit performers and bands.
