[FADCA] Re: Profiles for link from JAX to TLH

Chuck, thanks. These look good.

 I suspected the problem with the Live Oak to TLH path.

Doug, there is a tower in Madison that the public utility
has that might work.

It is about 30 deg 28 min30 sec N 83 deg  23 min 30 sec W
with tower height of 322' with a totall height amsl of 514'

Chuck can you try the Madison site as "site X" for a couple
of plots, LO to Madison, Madison to TLH?

If you and I both ask about it, may be we can find a  place
for what Chuck latter called "site X".

I am working on the Highlands site.

Chuck, could you run a path from the following "Penny Farms"
site to the Live Oak site (I am already on the "Penny Farms"
site below.)?

Penny Farms:

29 deg 58 min 58 sec N 81 deg 55 min 07 sec W 

antenna height 265 ' above ground. ( for info the site
ground AMSL is 150')
