On January 20, the CRTC approved the application for a licence for a French-language FM radio station at Sorel on the frequency 101.7 MHz, channel 269, with an effective radiated power of 3,000 watts. The licence would expire September 30, 1990. Radio Richelieu (1979) Ltée already operated CJSO-AM in Sorel and submitted this application to operate an independent station. According to the applicant, the replacement of its AM station with an FM station would improve the reception quality of its local service and enable it to overcome the technical problems it had encountered for a number of years. Consistent with the applicant's proposal, this approval was conditional upon the surrender of its licence to operate radio station CJSO. The Commission noted that the station would be operated in the "Group I" music format, with a vocal-to-instrumental ratio of 80/20, and would broadcast at least 65% French language vocal music. The applicant proposed to devote 12% of its weekly broadcast time to programs in the foreground format. The programs would be locally produced and consist among other things of public affairs and music (Category 5 - Music - general). The news broadcast would have a 30% local or regional content. The applicant would allocate two full-time journalists, one part-time journalist and two stringers to its news service.
