I do not mean to trash your posting but that 7 mile range from 2 watt units is under the absolute best of conditions meaning straight line, tall antenna, no obstructions.
It is not unusual for a 5 watt radio to have problems with hills and obstructions at only 2-3 miles.
Just don't want anyone to be unhappy.
Still, these go much farther than the old cheapo units we all used to use.
