Basic principles remain basic principles always, regardless when they are 
studied or analized, is it 1966 or 2006. For sure, there ARE several 
different layers of correspondents. And the layers depend of both antennae 
and location, too.

Just recalling, once I've had a very interesting observation a few years 
ago. It was right after a major international contest. I got a call from 
people located some 300 km west of my QTH. The guy was almost loughing and 
being quite sceptic saying, look, do you know your neighbour [call] who took 
part in the contest? Certailny I was and said, yes. And you know what, said 
the guy, your friend is totally deaf. We have heard him calling CQ TEST all 
the time, there was a crowd of US stations calling him but all of them got 
just another CQ in return... Is he deaf or what? Ha, ha, ha...
It was a perfect confirmation of a fact that between me (as well as my 
neighbour being the "deaf" guy) and the "good ear guys" there lays a border 
of 2 and 3 hops from the East Coast USA path. My friend, being one of the 
best CW operators I have ever seen , has been using an TS-850 + some 500 W 
and 3 ele full size beam for 40 m. I'm pretty sure, he is not deaf at all 
and he IS a great operator. But... His 3 ele plus 500 W transmitted were 
able to break another hop losses, so that the crowd of 100 W/wet noodle guys 
could hear HIM, but by return their energy could NOT break the 3rd hop power 
limit minimum required. Having had a couple of dB by, say, another element 
in his antenna array or so, he might open up another layer of asations, 
but... This is just reality. Me and my neighbour, we were at 3 hops from 
East Coast USA. The guy who were watching a crowd of callers was located at 
2 hops...

BTW I have also seen quite the same phenomenon (2 or 3 hops) having moved 
some 200 km North from the basic location.

Just wanted to emphasize the facts that there are different layers of 
potential correspondents, indeed, and even a few hundred km of difference of 
location are extremely important sometimes.
