[BC] 9th FM harmonic causing interference

Couple things here...

The 2Ghz transition delays were largely the result of broadcasters
equipment not be available to install.  The manufacturers were swamped
with orders and they could not meet those deadlines. Then came not enough
tower people qualified to do the work.  Then came the one or two laggard
broadcasters who's managers didn't believe it applied to their operation
and then were literally forced to move and convert kicking screaming.

I agree that MANY Nextel (Nexhell) people are idiots, including some top
managers. And there are an equal number of bone heads at Sprint too. But
in this case, the people I worked with were decent folks who wanted to
solve a real problem impacting their LICENSED operation.  I simply
eliminated the obvious and let them go searching for less than obvious.

Who was it that said, "When in doubt, eliminate all the possible options
and the solution will be obvious."

I see nothing wrong with that regardless of who they work for if the work
is a genuine and honest effort.  In the end well have the share the
spectrum. And I'd rather not be seen as a "pecker headed broadcaster".
