MCI Internet is messing up mail again, I tried to post this 
yesterday. I hope this makes it:

Thank's Bill for the relay from YB0ARA. At 1030Z I could plainly hear 
him calling about S5-6 through S9 QRN but only copied a partial call.

I'm testing antennas in the mornings with VK's and ZL's, comparing a
dipole (broadside east-west) at 260 feet height with the 4 square 
(110 ft in-line spacing with 120/240 degree phasing) and an omni- 
3/8 wl vertical. The four square points due southwest or northwest, 
and the dipole feedline and the 260 ft tower located 500 feet due 
west of the omni- and 4 square puts a null due wes. This null located 
due west hurts the verticals about 8 dB.

(I detuned the tower a bit better yesterday evening, and the west 
null affecting the vertical antennas is about 2-3 dB deep now) 

I'd appreciate reports from distant stations (even via e-mail) of 
signal changes when I send 1, 2, or 3. Be sure to mention date and 
time, because I change antennas to different switch position numbers 
once in a while (and sometimes skip one antenna and do two numbers on 
the same antenna) to do a control check.

Please e-mail me directly with reports during a 1, 2 ,3 switch beyond
2000 miles or so west. If any Europeans or Africans would like to try
my sunset (0100Z), I'd like to do some sunset antenna and propagation 
tests also.
