[BC] Re: Franklin Networks

WTMJ is just up the road from our 1130.... we have the filters to prove 
it ;-)

WTMJ doesnt run sectionalized.  They have 4 towers that are 90 degrees, 
and two they add at night that are about 70 degrees.

We are certainly in tower land.... WTMJ with six and ours with nine.
