KSJS (90.5 MHz) is a college radio station that broadcasts 24 hours a day from the campus of San Jose State University in San Jose, California, USA. It went on the air on February 11, 1963, with only 85 watts of power. The studio is located in Hugh Gillis Hall, easily accessible to RTVF majors. Originally, its transmitting antenna was installed atop the Walquist Library Building on campus, but broadcasting range was adversely affected due to the nearby Bank of America Building's superior height. Today, however, its transmitter atop Coyote Peak broadcasts 1500 watts, allowing the station to be heard by the entire Santa Clara Valley and much of the San Francisco Peninsula. Currently, the station features five musical formats: urban, electronic, subversive rock, rock en Español, and jazz. It also has a variety of specialty broadcasting, including Radio Ethiopia, Mecca One, Celluloid Dreams, and the Disco Funk Explosion. The station is almost entirely student-run, and was one of the first radio stations in the nation to stream its programming over the Internet.
KSJS carried regular news programs produced by San Jose State's Radio-Television News Center, which had been started by Professor Gordon Greb in 1957. The programs in the 1960s included a world and national news program, broadcast shortly after the daily sign-on, and "Spectrum," a college news program with emphasis on San Jose State news.
From the 1970s through the early 1980s, KSJS was heavily-formatted, with students learning to "talk up" records, play public service announcements at appropriate times and even "backtime" songs to a top-of-the-hour newscast from Mutual News. In recent years, the station has taken on more of a free-form approach. KSJS has been named "Station of the Year" twice by the National Association of College Broadcasters.
