You're probably right, but their coverage is horrible (and pretty much always has been), compared to 88.1, 88.9, and 89.7. If the power was anything above 500 watts, at that height, I'd still take the leap. I think I was once quoted a price of around 10 grand to purchase the band filters, to be part of the system (that was in the early 90's). I will always regret not pursuing that, as an option.
