When I first heard them here about a yeaar and a half ago (or whenever), they dominated 1220 for a week or two, IIRC, I wouldn't be surprised if maintaining their pattern can be problematic. They're pretty close to the 50kw 1220 in Cleveland. Especially for a 10kw facility. It;s only about a four hour drive from Cleveland to St,Catherines, And that's via a a land route around Lake Erie!
Id say it is problematic with 9 towers!
