1909 __ 24-hour broadcast of music and news — The first radio station
Charles David Herrold (1875-1948)
Comment : Charles David Herrold begins a 24-hour broadcast of music and news from the Herrold’s College of Wireless and Engineering in San Jose, California, using a 15 w spark transmitter. Herrold carried on with a regular schedule of transmissions (off and on) until 1917. His station, later known as Herrold’s School of Radio (call letters FN, 6XE, 6FX, and SJN), eventually became KQW in 1921 and then KCBS in 1949.Charles David 'Doc' Herrold, (November 16, 1875 – July 1, 1948) was an American radio broadcasting pioneer who in 1909 created the world's first radio station. Interested in radio to transmit voice signals, he began broadcasting music and entertainment on a regular basis between 1912 and 1917 to fellow radio enthusiasts, using the callsigns FN and SJN. He had the world's first regularly scheduled broadcasts, allowing listeners to tune in at a known time. However, in 1917, the US government ordered non-military radio transmissions to cease. After World War I, Herrold obtained the license for KQW in 1921, but he was unable to maintain the financial requirements, and the station was sold several times. In the 1940s, CBS attempted to buy its then-affiliate in San Francisco, KSFO. KSFO refused to sell, so CBS purchased KQW, moved it to San Francisco and changed the call letters to KCBS. (Compiled from various sources)Charles David Herrold, in San Jose, Calif., in 1909, established a radio-telephone station for experimental work and as a promotional device for a school of engineering and radio, which he also operated. 'This is San Jose Calling,' the station of the Herrold College of Engineering and Wireless, would identify itself and then, using a 15-watt spark transmitter and water-cooled microphones, broadcast music and news. Mr. Herrold's station grew into KQW in 1921 and KCBS in 1949. It's now a 50-kw CBS-owned station in San Francisco. Charles David Herrold, also a microscopist and astronomer, built his own telescopic and driving clock, an observatory, a high-speed focal-plane shutter to take photographs of the sun; produced more than 50 different electrical devices in dentistry and surgery; perfected an electrical deep-sea illuminator used by salvage companies and pearl fishers; developed electrical machinery for pipe organs and designed a high-speed turbine.
