Didier, that ought to be just about in your back yard!! I did some consulting
for one of the Dothan TV stations last year (what's amazing is that the
transmitter is actually in Florida!). Anyway, on my way there from a military
reunion in Texas, we stopped in Shalimar to visit my old roommate that didn't
make the reunion. If I had known then where you live, I would have stopped by to
see you... He's probably about a mile from your place!

DJ,
Actually, you are closest to the Malone, FL LORAN, about 30 miles due
south of Dothan, AL. They run 800kW into a 700 foot monopole array. For
more info see http://www.uscg.mil/d8/lorstamalone/default.asp .
