[Elecraft] K3 PRE function question

[David Ferrington, M0XDF]

My God - if we had a lake, it would be ~ 1/8 acre per property, if you were lucky - 3-5 people per property.

I live in a medium sized town 30 miles from the centre of London, population ~ 250,000 in < 70 sq-mi :-(

I really hate this damn machine, I wish that they would sell it.
It never does just what I want, but only what I tell it!

Density = 4200/160 = 26 people per sq-mi.  But that is not accurate for my nearby density around a lake with average property size of 2-3 acres and 2.5 persons per property.  Probably 200-300 within a mile.  All have wireless devices and consumer electronics galore.  Many are line of sight across the lake.  I do have buired utilities in the near 1/4 mile but overhead wired beyond that.  Internet is phone line DSL and TV by satellite.

Another city of 7500 lies another 11 miles south to the first so in 30-mile radius we have a pop of about 30,000.
