Shortwave station VONH began operation to rebroadcast the programming of VONF St. John’s.


Newfoundland joined Canadian confederation as the country’s tenth province. Stations of the Newfoundland Broadcasting Corp. had their call letters changed April 1 when the Canadian Broadcasting Corp. took over operation of the stations as a supplementary group to the Atlantic region of the Trans-Canada network. VONF St. John’s was now CBN and the shortwave outlet became CBNX.


The “CB” call letter prefix had always been assigned to Chile and not Canada. Under special agreement, the CBC had been allowed to use that prefix for its stations. As CBNX

was operating on an international frequency, the call sign was changed to CKZN in 1965.


On March 11, the CRTC approved the application to amend the licence for CKZN St. John’s by increasing the power of the shortwave transmitter from 300 watts to 1,000 watts. The CBC indicated that the increase would improve service in remote areas of Labrador.


CKZN began offering part-time programming from CFGB Happy Valley-Goose Bay, in addition to what was already being offered by CBN St. John’s.


CKZN became a full-time rebroadcaster of CFGB. No more programming originated from CBN. The station continued to operate at 6,160 kHz in the 49 metre band. On Canada’s west coast, the CBC also operated station CKZU on the same frequency, rebroadcasting the programs of CBU 690.

Effective September 1st 2019, we will only be adding new material to these station histories in exceptional circumstances. Our intent to chronicle the early days of these radio and television stations has been achieved, and many new sources and technologies, from the CRTC website to Wikipedia, and others, are now regularly providing new information in these areas.
