1946
In November it was announced that CKOK was expected to go on the air soon. The station would broadcast on 1450 kHz using a Marconi 250 watt transmitter. In the early going, program service would be carried by landline from CKOV in Kelowana.

In December CKOV engineer Fred Webber was busy getting CKOK ready for operations. The station did begin operations this month and was owned by Okanagan Broadcasters Ltd.

1947
A formal reception marked the opening of new studios and offices for CKOV (Kelowna), operated by Okanagan Broadcasters Ltd. CKOV had first gone on the air 15 years earlier as amateur station 10AY. CKOV had what was likely the first satellite commercial station in Canadian radio with CKOK Penticton. CKOK opened as a repeater of CKOV and its purpose was to provide a signal in the Penticton area which had been isolated especially at night by the mountainous terrain. The only difference between the two stations was the call sign. That difference was handled with the flick of a switch from the Kelowna studios.

1948
In May, the CBC approved the conversion of CKOK from a satellite of CKOV Kelowna into an independent station. The licence was requested and approved in the name of CKOK Ltd., with control held by J. Reg Beattie, formerly with All-Canada Radio Facilities Ltd. and CHML Hamilton.

CKOK applied to move from 1550 to 800 kHz. Power would remain 250 watts. The CBC recommended the application for approval.

Harry O. Watts was manager and Jean G. Griffiths was commercial manager.

CKOK moved to 800 kHz with a power of 250 watts.
