WEXP opened its studio at La Salle University in 1972. Initially, the radio station could only be heard inside the Student Union building, and the start-up price for the station was around US$7,500 ($1,000 of which came through a donation from U.S. Ambassador to Britain Walter H. Annenberg). Airing on 640 AM, “EXPlorer 64” was founded as a co-curricular activity, and was tied directly to the Marketing Department and the English Department’s Speech and Drama course. Much of WEXP’s early programming featured commentary opposing the Vietnam War, and oldies music. Coverage of La Salle basketball was also aired live from as far away as Arlington, Virginia. The station only aired from 10 a.m. to 3 p.m.
