CHYK and its Sudbury and Nipissing sister stations CHYC, CHYQ are the only francophone commercial stations programmed entirely in Ontario. Apart from commercials and separate morning shows, the three stations in fact simulcast the same programming at almost all times, although all three stations produce a portion of the shared broadcast schedule.
History
The station was originally established on December 23, 1951 by J. Conrad Lavigne, with the callsign CFCL at 580kHz. It operated as a private affiliate of Radio-Canada's French radio network, and was one of the few private affiliate stations of a CBC radio network anywhere in Canada. CFLH in Hearst began broadcasting the same year. In 1956, Lavigne also established CFCL-TV, a private CBC Television affiliate, in the city.
Trichlorofluoromethane, also called freon-11, CFC-11, or R-11, is a chlorofluorocarbon. It is a colorless, faint ethereal and sweetish odor liquid that boils at about room temperature.
Uses
It was the first widely used refrigerant. Because of its high boiling point (compared to most refrigerants), it can be used in systems with a low operating pressure, making the mechanical design of such systems less demanding than that of higher-pressure refrigerants R-12 or R-22.
Trichlorofluoromethane is used as a reference compound for fluorine-19 NMR studies.
Prior to the knowledge of the ozone depletion potential of chlorine in refrigerants and other possible harmful effects on the environment, trichlorofluoromethane was sometimes used as a cleaning/rinsing agent for low pressure systems.
