I really doubt that Clear Channel is going to let Bonneville put an FM antenna on one of their AM towers. Anything extra attached to an AM tower is a loser anyway. It's a problem. There is a newer tower in Wilder just above I-275 if you're going east. That looks like an incredible site for an FM, but you'd have to get an entirely new study doen, and since it's not too far from Taylor Mill, the result is probably the same or maybe NOT as good becasue that small amount of distance could cause an overlap.
If there's any potential gain from an upgrade, I'm sure they'd do it. But watch for Country on 94.1 or 96.5 if the rock format suddenly takes a dive. B105 is hurting Warm and WGRR. That's gotta be stopped if you're Cumulus. Even if Country stays on 97.3, it's such a non-factor it won't matter. Maybe they'll move it to 94.9 again? That wouldn't piss anybody off!
