CBX Lacombe Alberta signs on

In 24 August 1948, at 10:00 a.m., CBX Lacombe, Alberta, signed on, although the official opening was not until September 8th. The CBC hoped to repeat 1939's success with CBK-540, which provided local-like coverage to both Saskatoon and Regina, as well as serving almost all of the rest of Saskatchewan. They really did try hard, using a North-South directional pattern that pushed more of the 50,000 watts to Calgary and Edmonton than a single tower, non-directional pattern like CBK's would have. And twin 5/8 wavelength towers almost exactly half way between Edmonton and Calgary. But CBX's 1010 KHz frequency had nowhere near the groundwave coverage of CBK's lowest possible frequency, 540 KHz. Not to mention Alberta's more difficult terrain as well as larger buildings in the larger cities of Edmonton and Calgary.
