When W&J College, in Washington, PA, 25 mi. south of Pittsburgh, 40 mi. north of Morgantown,a nd 30 mi. east of Wheeling, were looking to move into the non-comm band, 91.7 was our best choice.
We had to protect, and essentially direct away from, WYEP/Pittsburgh at 91.3. Our antenna couldn't go NE of WashPA, and we had to direct our signal, or adjust so that it didn't interfere with WYEP.
Interestingly though, we didn't have much to worry about with WCVS (now WCAL) in California, PA--about 25 mi. east of WashPA. They're at 91.9 and 3kw.
I guess what this means is that, unless you're and old-school short-spaced non-comm allotment, you have to protect existing non-comm channels as you would commercial channels. If it means directionals, or Class A power, so be it.
