Which, incidentally, goes a long way toward explaining why the northeast 
in general and New England in particular drew so little in the way of 
X-band allocations. Being on the edge of the country, few New England

stations elsewhere. I'm surprised 930 in Rochester qualified; it's 
easier to see how 980 in Troy did, given the interference it generates 
to stations such as WCAP and WTEM (WRC).

I believe that loophole actually specified "only broadcast facility," 
which might explain why WJIB couldn't use it - WMBR and WHRB, as well as 
WLVI, also being licensed to Cambridge. (I believe, also, that the 
loophole has since been closed; I had an idea a few years back about how 
it might have been exploited in another location and found it wasn't
