naval.com is not even close to Chapman's calculations.
6 ft antenna on either end produced a 6 mile range according to navel.com.
Am I doing something wrong???

This made me think. SO I went to "How Stuff Works" to find the following formula:
SquareRoot(height above surface / 0.5736) = distance to horizon.
That works out to about 1 mile for every 8 inches in height. So a 6' antenna (72 inches) has a line of sight of 9 miles.
I wonder if the current Chapman's still has the old guideline? My copy is from the late 1970's.
