(619 kHz) was reserved for broadcasting official weather and other government reports. On May 4, 1922, the Detroit Free Press newspaper was issued a license, with the randomly assigned call letters of WCX, for operation on both broadcasting wavelengths. WCX made its debut, broadcasting from the Free Press Building, on the same day it was licensed. The inaugural broadcast included an address by Michigan governor Alex J. Groesbeck. 1922 saw a rapid expansion in the number of broadcasting stations, most sharing the single entertainment wavelength of 360 meters, which required progressively more complicated time sharing schedules among stations in the same region. The Detroit News, which operated station WWJ, bristled at having to suffer the "handicap" of being required to give up some airtime to WCX, which had, in the words of the News, decided to "break in". In late September 1922 a second entertainment wavelength, 400 meters (750 kHz), was made available for "Class B" stations, which had higher powers and better quality equipment and programming. Both WCX and WWJ qualified to use this new wavelength on a timesharing basis, and WCX ended use of the 485 meter "market and weather" wavelength. In early 1923 the United States further expanded the broadcast station frequencies into a band running from 550 to 1350 kHz. The Class B frequency of 580 kHz was designated for use by qualified stations in the "Detroit/Dearborn" area, and both WCX and WWJ were assigned to this frequency. On December 8, 1924, WCX opened studios atop the new Book-Cadillac Hotel in downtown Detroit, with transmitter facilities on the roof. Hometown poet Edgar A. Guest and the Jean Goldkette orchestra participated in the program. In January 1925, WWJ's reassignment to 850 kHz left WCX as the sole station remaining on 580 kHz. WJR-WCX On August 20, 1925, the Jewett Radio & Phonograph Company received a license for a new station, WJR. The company also took over WCX, consolidating operations in Pontiac, Michigan, as WJR-WCX on 580 kHz. Goodwill Station ownership On January 1, 1927, the station was taken over by George A. Richards, a local Oakland-Pontiac automobile dealer. Richards would later also assume control of WGAR in Cleveland and KMPC in Los Angeles. WJR adopted the slogan "The Goodwill Station" and on May 9, 1927, began carrying programs from the recently formed NBC Blue network. In mid-1927 the joint stations moved to 680 kHz. On November 11,
