CBKST Saskatoon signed on the air October 17. It operated on channel 11 with an effective radiated power of 325,000 watts.

When CBKST had its licence renewed, the following rebraodcast transmitters were also renewed (this list may not represent all of CBKST's transmitters as some licences may have been renewed on other dates): CBKST-1 Stranraer and CBKST-2 La Ronge.

1990
On March 28, CBKSTT was authorized to add CBKPT Patuanak to its list of rebroadcasters. It had operated as a transmitter of CBKT Regina. 

1991
The CRTC approved the CBC's application to change the program source of CBKST to originate from the studios of CBKT Regina. While CBKST would no longer produce any locally-originated programming, the CBC would continue to operate CBKST as a contributing bureau and maintain master control facilities in Saskatoon allowing the station to continue to broadcast station identification (including call sign channel designation and location) as required by the Department of Industry, as well as public service announcements, occasional specials and commercial messages. 

On July 23, the CRTC approved the application to amend the broadcasting licence for CBCS-TV-1 Meadow Lake, by changing the program source from CKSA-TV Lloydminster, Alberta to CBKST-3 Leoville, Saskatchewan. MidWest Television Ltd., licensee of CKSA-TV expressed concern for the loss of the service provided by its station to viewers in Meadow Lake and suggested that the interference problems affecting the programming feed from CKSA-TV could be resolved at the CBC's expense.  The CBC responded, noting that the proposed change of program source would offer viewers provincial programming content reflective of Saskatchewan issues, and eliminate time zone differences. The CBC further stated that the intervener had acknowledged that the costs associated with a microwave or fibre-optic link were prohibitive and that its proposal should result in a signal of improved quality. 

1994
On November 23, CBKST-2 La Ronge was authorized to increase power from a transmitter power of 8.9 watts to an effective radiated power of 190 watts. The increase would provide service to an additional 500 residents.

2005
