History Organized radio broadcasting began to gain prominence in Canada in early 1922. Initially there wasn't a formal licence category for stations providing entertainment broadcasts intended for the general public, so the earliest stations operated under a mixture of Experimental, Amateur, and governmental authorizations. One of the most prominent pioneer broadcasters was William Walter Westover Grant, who during this time installed radio communication equipment for the Canadian Air Board's Forestry patrol. In 1921 these operations were established at the High River Air Station in southern Alberta. Grant constructed government station VAW at this site, and, in addition to the forestry work, began to make a series of experimental entertainment broadcasts, believed to be the first in western Canada, that were audible approximately 50 miles (80 km) away in Calgary. (In May 1922 Grant founded CFCN (now CKMX) in Calgary.) In the spring of 1922 the Calgary Herald began to publicize the topic of radio, including Grant's broadcasts. In late April the newspaper installed what it called "the most complete receiving set in Western Canada" at its headquarters, and reported that it had successfully picked up High River concerts on April 27 and April 28. During this same time the Canadian government announced the formal creation of a radio broadcast service, which included the establishment of a "Private Commercial Broadcasting" licence. In late April 1922 an initial group of twenty-three commercial broadcasting station licences was announced, including one issued to the Herald for operation on 400 meters (750 kHz), with the randomly assigned call letters of CHCQ. CHCQ's transmitter and studio were located in room 1006 on the tenth floor of The Herald Building. The primary technical work was performed by G. J. J. Jermain and S.
