KICR is 172 watts from a tower that is 1,844 feet above average terrain, several hundred feet taller than the Empire State Building. KICR plays country music and is licensed to Coeur D'Alene in Northern Idaho. My guess is, that's what folks in Northern Idaho listen to, not to one of Spokane's two country stations.
Northern Idaho is fairly rural and agricultural, great for a local country station. In the Spokane market, a listener in Northern Idaho counts as much as one in downtown Spokane. So while KXLY-FM and KDRK are the country stations for Spokane and Eastern Washington State, KICR is the country station for Northern Idaho, where country is a way of life.
Admittedly, KICR's ratings do wobble. In the 3's in January, in the 5's in March. That's probably a function of where the diaries are. Perhaps this time around, more diaries came from Northern Idaho. I notice the rock station for Northern Idaho, 94.5 KHTQ in Hayden, also wobbles. Since January, it's gone from the 4's to the 2's. So maybe some folks in Northern Idaho are recently listening more to country, less to rock.
