The CBC has taken a different approach to AM in the Canadian west. It 
recognizes that the huge signals from CBW, CBR, CBX and CBK effectively 
cover enormous swaths of emptiness that would be economically impossible 
to replicate with FM transmitters. So it's leaving those signals (and 
CBU Vancouver, too) on AM, but it has put "nested" lower-power FM relays 
on the air to provide FM service to the core of each urban market. In 
Winnipeg, it's CBW-1-FM, running 2800 watts on 89.3 from a rooftop 
downtown.
