Don't get too hanged up on mirrors. There is also quite a bit of refraction -
ducting going on especially on lower frequencies. See my article at
http://www.k3bu.us/propagation.htm
one time was poo-pooed as ridiculous, now it is getting more acceptance that we
are also ducting, besides "mirroring". How do you model atmo/ionosphere between
here and Eu? Car (or animal :-) exhaust and a flashlight?
Just think, on long, medium waves and 160 you can hear the station's signals
from "here" to DX "there" and everything in between, hardly any "skip" or
bouncing mirrors, or dead "skip" zones (mostly).
Recent example from SN3R comment: "All overseas signals weak, excepting VY2ZM,
W3LPL and K3BU who was 57 one hour after my SR!" We have comparably similar
stations, able to "shoot" at low angles, yet there was not a peep from Euros
around that time - S7 vs. nil.
How many times some can not work station when it peaks on receive (keeps CQing)
and a bit later when signal is dropping, they would come back. Yes there is
spotlight, polarization shift, varying angles, but denying that there is one
way (enhanced) propagation and trying to replace the complicated
atmo/ionosphere with mirror and laser is just plain simplistic and proves
nothing.
Reminds me old argument that we had here that it is impossible to have 160m
signals coming at high angles, that way back I described, now it's OK (as well
as "long beverages are no good" and "3/8 vertical can't beat 4 sq at low
angles", etc.)
Anyway, top band records are updated, congrats to new CQ WW CW "beaters": low
power - K1PX, VP9I (WA4PGM); high power - GM3POI, W4ZV, K3BU/8. Any goofs,
please let me know. Let's hope for some decent propagation for CW weekend.
