G. Thomas Desjardins was granted a licnence for a new AM radio station at La Pocatiere, near Quebec City, on the south shore of the St. Lawrence. The station would operate with a power of 100 watts on a frequency of 1200 kHz.
CHGB signed on the air in August.
Under the Havana Treaty CHGB moved from 1200 to 1230 kHz (Class IV) on March 29. Power was 100 watts.
CHGB was added to the CBC French network.
The station was granted a power increase to 250 watts and that power level was adopted later in the year.
CBC Quebec Regional Network Supplementary Stations: CKCH, CHGB, CHNC, CKRN, CHVD, CHAD.
CHGB had a relay station at Murray Bay.
G.T. Desjardins was manager.
CHGB moved to 1350 kHz and daytime power increased to 1,000 watts. Night power remained 250 watts.
CHGB applied for permission to operate a shortwave station. The application was denied.
In the past, the CBC Board approved the formation of a second French radio network - the French Radio Association Ltd. The six stations in the network were now (late 1950) broadcasting commercials for a dozen national sponsors. The stations were CKVL Verdun, CKCV Quebec, CHLT Sherbrooke, CHEF Granby, CJSO Sorel and CHLN Trois-Rivieres. There were also two supplementary stations - CHRL Roberval and CHGB La Pocatiere. The network signed its first commercial contract in October of 1948. In 1949, the group broadcast 44 hours of commercial programming and 132 1/2 hours of sustaining programs.
CHGB became a member of the Canadian Association of Broadcasters.
By this time, CHGB was owned by CHGB Ltee. (G. T. Desjardins 98.8%, A. Dube 0.4%, Ross J. Desjardins 0.4% and A. Treve 0.4%) and was an affiliate of the CBC's French language radio network. Georges Desjardins was president and general manager.
CHGB increased power to 5,000 watts.
CHGB was now operating on 1310 kHz. Power was 5,000 watts. G. T. Desjardins was President of CHGB Ltee. P. E. Hudon was CHGB's manager.
CHGB-FM signed on.
CHGB received approval for an auxiliary studio at Baie-Saint-Paul.
On May 28, CHGB Ltee was given approval to increase CHGB 1310’s day-time power to 10,000 watts from 5,000 watts. Night-time power would remain 5,000 watts. CHGB would continue to operate with a directional pattern at night.
Radio La Pocatiere Ltee. was given permission to purchase CHGB-AM and FM from CHGB Ltee on December 15.
On June 14, Radio La Pocatiere Ltee received approval to operate an AM station at St-Pamphile.
CHAL 1340 St-Pamphile signed on the air. It was a part-time rebroadcaster of CHGB.
Radio La Pocatiere Ltee. purchased CHAL St. Pamphile. On the air since 1973, CHAL became a part-time rebroadcaster of CHGB.
The CRTC approved a share transfer for Radio La Pocatiere Ltee (CHGB-AM-FM and CHAL St. Pamphile).
CFVD signed on the air in Degelis and rebroadcast some programming from CHGB.
CFVD Degelis stopped airing programs from CHGB.
On August 15, Radio La Pocatiere Ltee was given approval to delete approximately 16 hours a week of local programming on CHAL St-Pamphile and substitute it with programs from CHGB. As a result, CHAL would become a full-time rebroadcaster of CHGB. Approximately 15 hours of programming a week on CHGB (and as a result of this decision, on CHAL) originated with CJFP Riviere-du-Loup.
On January 11, the CRTC renewed CHGB-FM's licence until September 30, 1985.
CHGB and CHAL became full-time rebroadcasters of co-owned CJFP Rivière-du-Loup.
The corporate name changed to CIBM-FM Mont-Bleu Ltée.
CIBM-FM Mont-Bleu Ltee was given approval to move CHGB to the FM dial. It
would broadcast some programs originating in the La Pocatière and Cap-à-l'Aigle studios and some received from CIBM-FM Rivière-du-Loup and CITE-FM Montreal. The CRTC did not accept CHGB's proposed use of 105.1 MHz with an effective radiated power of 7,900 watts. The applicant was told its signal must not cover Rivière-du-Loup. CHGB and its rebroadcaster, CHAL St-Pamphile, would have to continue as Radio-Canada affiliates for another year. During that time, the CBC would have to find a way of continuing its French network coverage in the area.
The licensee later proposed to operate what would now be CHOX-FM on a frequency of 97.5 MHz with an effective radiated power of 25,160 watts. The transmitter site would be re-located to Saint-Onésime to ensure the 500 uV/m contour excluded Riviere-du-Loup and surrounding area. The CRTC approved the changes.
On April 23, CHOX 97.5 replaced CHGB and CHAL. The AM transmitters left the air on June 19 when their licences were revoked by the CRTC.
CHOX-FM was given permission to add a transmitter at Baie-Saint-Paul, operating on 94.1 MHz with an effective radiated power of 7.9 watts.
Approval was given for CHOX to add a transmitter at Sainte-Perpétue, operating on 101.1 MHz with an effective radiated power of 16.1 watts.
On April 28, CIBM-FM Mont-Bleu ltée was given approval to add a transmitter for CHOX-FM at Saint-Aubert, operating on 100.1 MHz with an average effective radiated power of 12 watts.
On August 14 the CRTC renewed CHOX-FM's licence until August 31, 2015. The renewal included rebroadcast transmitters CHOX-FM-1 Baie Saint-Paul, CHOX-FM-2 Sainte-Perpetue and CHOX-FM-3 Saint-Aubert.
