I did not find the power level. Generally the .5 watt FRS are
advertised as 2 mile. 2 watt would be 4 miles. 4 watt would be 8 miles,
and 8 watt would be 16 miles. This just equates to signal level.


Your math is off a bit.

From your starting point at 0.5W and supposing 2 miles, to double the range
to 4 miles would require 2.0W (4x the power to double the distance). To
double it again would be 8.0W for 4 miles, then on to 32.0W for 8 miles.
This is based upon free space loss only, from point to point line of sight
with no obstructions. There is a bit more loss to be computed in for
atmospheric losses at 460MHz.

Well I started off OK. Perhaps I was unintentionally trying to match the
companies claims for didtance.
