"arc fone" radiotelephone, he produced a system with good quality audio—colloquially described as "shaving the whiskers off the wireless telephone"—although relatively low powered. A number of successful tests for the U.S. Navy were reported, however, a conflict soon arose between Herrold and the company, and in late 1913 he both resigned and sued NWT&T on the grounds that he had not been fully compensated for his time and effort. NWT&T counter-claimed that it had met the terms of its contract and moreover "most of the improvements made by Herrold were ultimately abandoned by the company". The judge sided with NWT&T and denied Herrold's claim. In addition, despite his attempts to create a transmission system that didn't infringe on the Poulsen arc patents, there were doubts that he had actually achieved this goal. Concurrent with his work for NWT&T, in July 1912 Herrold began making regular radio broadcasts on a weekly basis from his San Jose school, with an initial broadcast featuring phonograph records supplied by the Wiley B. Allen company. Herrold's wife at the time, Sybil, later recounted that she participated in the Wednesday night programs, where she broadcast recordings from the Sherman, Clay record store that had been requested by "the little hams" (amateur radio enthusiasts) who comprised her audience. Herrold's ultimate transmitter design employed a water-cooled microphone connected to six small arcs burning in liquid alcohol. A review of a Christmas 1916 concert complimented the good audio quality of the "Herrold-Portal aerial system of telephony", reporting that "It was as sweet and beautiful as if it had been played and sung in the next room". Despite the popularity of the broadcasts, they drew only local attention, and were largely unknown outside of the immediate San Jose area. Moreover, the broadcasts came to an end on April 6, 1917, when all civilian station operations were suspended as a result of the entry by the United States into World War I. After dismantling the station, which included removing the antenna system from atop the bank building, Herrold relocated his school to 467 South First Street, a site which also included retail space. World War One Although during the war the school no longer had an operational radio station, there was an extensive need for radio operators, so recruits were trained using Omnigraphs for Morse code instruction. Herrold would later advertise that the school's "war record" consisted of "200 Men Trained—130
