KALX (90.7 FM) is an FM radio station that broadcasts from the University of California, Berkeley in Berkeley, California, United States. KALX, a community and student-run radio station licensed to the university, broadcasts in stereo with 500 watts of power. The station employs three full-time paid staff members, but is largely run by its nearly 300 volunteers, including Berkeley students and other members of the local community.
The station originally began broadcasting in 1962, as a carrier current station. By 1966, KALX (then known as Radio KAL, the call letters being derived from Berkeley's nickname "Cal") had moved from Berkeley's dormitories to Dwinelle Hall on campus, and Berkeley administrators began investigating the possibility of applying for a broadcast frequency for the station. KALX received its broadcast license and made its first FM broadcast, with 10 watts of power, in 1967. The studio in the basement of Dwinelle was modest, a small chamber sequestered off from a sizable library of albums.
In the 1970s, KALX was taken off the air for a short period by the faculty oversight Radio Policy Board after the station manager and friends had abused their use of university automobiles for private use and run up large bills for long distance phone calls to their contacts in Los Angeles and elsewhere. After an investigation, the station was put back on the air in 1975 under new management, led by Andrew Reimer who had previously been manager of KUCI, the radio station at UC Irvine. The station progressed from a 10 watt part-time operation to continuous operation in 1977, to a higher transmitter site in the Berkeley hills in 1978.
In 1981, the station began a successful fundraising drive to boost its power level to the present-day 500 watts, a level that was reached in 1982.
