KALW
KALW (91.7 MHz) is a non-commercial FM public radio station, owned by the San Francisco Unified School District (SFUSD), and serving the San Francisco Bay Area. Its studios are in Phillip and Sala Burton Academic High School off Mansell Avenue in San Francisco. KALW operates as a community public station, incorporating volunteers in its news and music programs. The station's programming is also streamed on its website.
KALW is a Class B1 FM station and one of the oldest educational FM stations in the U.S. It has an effective radiated power (ERP) of 1,900 watts. The transmitter and tower are on Twin Peaks.
KALW is an independently-operated National Public Radio (NPR) member station, carrying content from NPR, American Public Media, Public Radio International and the BBC World Service (heard overnight). KALW also produces its own local news, music and interview shows, including the live weekday call-in program Your Call and the morning news magazine Crosscurrents. It had offered a weekly two-hour live variety program West Coast Live!, broadcast each Saturday morning. But it ceased production in December 2018. National shows produced at the station include Inflection Point with Lauren Schiller.
On weekdays, KALW carries popular NPR news shows: Morning Edition, All Things Considered and Fresh Air. Evenings and weekends, one-hour weekly public radio specialty shows include: Splendid Table, Hidden Brain, The New Yorker Radio Hour, Le Show, This American Life, To the Best of Our Knowledge, Reveal, Big Picture Science, Science Friday, Radio Lab, Snap Judgment, It's Been A Minute, Living on Earth, Hearts of Space and Wait, Wait, Don't Tell Me.
As a part of its affiliation with the San Francisco Unified School District, KALW carries broadcasts of its monthly board meetings. There are also daily listings of school lunch menus, which are occasionally read by celebrities who come to the station for interview shows.
In the late 1930s, San Francisco was a major center for radio development in the Western United States. In 1939, General Electric established a powerful shortwave radio station in conjunction with the opening of the Golden Gate International Exposition on San Francisco Bay at Treasure Island, San Francisco. In August 1940, the Radio Corporation of America (RCA) gave a demonstration of the then new technology of frequency modulation (FM) broadcasting at the National Association of Broadcasters convention being held in the city.
In May 1940, the Federal Communications Commission (FCC) announced that effective January 1, 1941, it was establishing a broadcast band for FM stations, operating on 40 channels spanning 42–50 MHz, with the first five channels reserved for educational stations. That same month the San Francisco Unified School District filed an application to construct a new educational FM station, operating on 42.1 MHz with 1,000 watts. The original station application, filed May 24, 1940, specified use of General Electric transmitters, but this was changed in January 1941 to specify an RCA FM-1-B transmitter.
KALW was constructed at Samuel Gompers Trades School and began test transmissions on March 10, 1941. It became the first FM station to operate on the West Coast. It was also the second U.S. educational station to begin broadcasting on the FM band. The station entered general service providing instructional programming on September 1.
