Hey...looks like the FCC will accept a model instead of a field proof of 
performance (at least in some situations)

"Back in September, after a 19-year wait, the FCC approved the 
much-anticipated rules that will permit computer modeling of AM 
directional arrays as a means of directional antenna performance 
verification. The NPRM came out early last spring and generated a lot of 
hubbub at the NAB spring show and through the summer. Now, the rules 
have been approved by the FCC and are slated to become effective in 
February."


and, by the way, the rules about structures owned by licensees within 
some distance and notifications, etc., have been in place for some 
years, specifically  47CFR 22.371 and 47CFR 27.63 (I found an article 
from 2003 that talks about it).  So this new rule might be the computer 
modeling aspect.  It might also only apply to some services and not 
others.  (For instance, does it apply to the operator of a construction 
crane, or the builder of a multi story building?  )
