"This is CBC Radio One. 98.9 FM in Yellowknife" was the rather unexpected announcement on 1280 kHz one evening in November last year. CBQT Wrigley is one of CBC's low-power repeater stations, and the only one on 1280. An email from CBC North confirmed my reception, thanks to Ole Forr who first spotted it. The distance is 4975 km, so even 40 watts can travel great distances when propagation is right.
Wrigley has around 130 inhabitants, and is the end point of the Mackenzie Highway. There is even an air strip at the east bank of the Mackenzie River. Canada MW verie #220.
