Here's a segment of the rules I downloaded a couple days ago:
******************
Rules, 1996 ARRL International DX Contest
[snip]
6) Contest Exchange:
(A) W/VE stations (including 48 contiguous United States
and does not include Canadian islands of St Paul and Sable) send signal
report and state or province.
(B) DX stations send signal report and power (three-digit
number indicating approximate transmitter output power).
7) Scoring:
(A) QSO Points--W/VE stations count three points per DX QSO.
DX stations count three points per W/VE QSO.
(B) Multiplier--W/VE stations: Sum of DXCC countries (except
US and Canada) worked per band. DX stations: Sum of US states (except
KH6/KL7) and District of Columbia (DC), NB (VE1), NS (VE1), PEI (VE1
or VY2), PQ (VE2), ON (VE3), MB (VE4), SK (VE5), AB (VE6), BC
(VE7), NWT (VE8), YUK (VY1), NF (VO1), LAB (VO2) worked per band.
Maximum of 62 per band.
(C) Final Score--QSO points X multiplier = final score.
8) Miscellaneous:
******* (F) Aeronautical and maritime mobile stations outside the US and
Canada may be worked by W/VE stations for QSO credit only.
****************************
(The above asterisks were added by me.)
It looks pretty obvious ... mainland W/VE works DX (including KH#/KL7)
and DX works W/VE. W's and VE's don't work each other.
Good luck in the contest!

Chuck, we agree on everything but style! HI Of course you need to do the
modeling to see what the exact results are, and clearly the antennas are in
the near field of each other. But I was trying to make a very simple
(simplistic was the word I used in the original note) description and that
description does fit what is observed by the many CONTEST operators who have
a two stack that can be pointed to spray in multiple directions.
It is fortuitous that for most common spray modes the antennas are pointed
at approximately right angles to each other, thereby minimizing the
interactions. Typically on 40M in the afternoon and evening they would be
pointed (from Colorado) at 35 deg (Eur) and 125 deg (Car). At midnight the
Eur goes to JA (320) and the Car goes to Eur (35). And after Europe drops
out the Eur goes to VK/ZL (230). (The choice of which antenna goes where is
a function of height, angle of radiation, and expected benefits (number of
potential qsos and mults) from one over the other in any given direction.)
Of course this works for Colorado but the pointing directions are somewhat
different for other parts of the country.
To summarize my points.
1) Two Yagis pointing in opposite directions on the same tower aren't
necessarily 180 degrees out of phase. You must also take into account the
spatial position of the phase centers of the two, in addition to the "phase
flip" on the driven elements. More easily visualized when talking about
long (in wavelengths) VHF antennas, where, when they are counter rotated the
driven elements could be multiple wavelengths apart.
2) It is a complex problem for accurate analysis and requires the use of
modeling tools but my description of what is operationally observed is
accurate. On receive, when switching from the two antennas spraying in
different directions to only one antenna there is never any dramatic
increase or decrease in the received signal from the direction of that one
antenna. Only a reduction in the qrn and qrm contribution made by the
pickup of the second antenna.
3) For DX contesting from the US, the major population and multiplier
centers are located in directions such that the antennas are at right angles
to each other and therefore have the least interaction. So it is not very
common in normal operation for the antennas to be pointed at 180 with
respect to each other.
4) Trying to explain things in simple terms, yet hinting at the complex
technical issues underlying the explanation, often results in the
sophiticated reader feeling that the answer is inaccurate or incomplete
(which it is and was intended to be). Any short, five-paragraph answer
without mathematics on a relatively complex antenna topic will always be
incomplete. I just hope the intitial answer as well as the dialog that it
has spawned is illuminating to the intended audience.

THESE ARE NOT OFFICIAL SCORES! I AM NOT A LOG CHECKER! DO NOT SEND ME ANY
LOGS!
Also if you do not mind, please do not attach summary files. It means I
have to go into a separate program to read them. Since I am doing several
contests and also have my own logs to handle, this will save me time.
Also remember when you see the FINAL POSTING on a contest that is what it
means. I will not accept scores after that. I assume two weeks is plenty
of time for anyone to get their scores on here. Remember these are only
claimed scores and not the real ones. You must remember that this weekend
is the CW ARRL DX. I will be doing scores for that also. I hope everyone
understands.

Subject: Posting of Scores ARRL DX!!!!!
Message-ID: <199602151600.LAA26932 at mail-hub.interpath.net>
Hello Fellow Contesters,
As always I will be doing the scores for the upcoming ARRL DX, both CW &
SSB. I am going to try and submit some guidelines here that will make it
I hope easier on you and me. This job does take quite a bit of time and
these are only a few pointers that may save us both time. This list has
been compiled from the other contests I have done. You can feel free to
write to me, not the reflector about any suggestions that you would like
to see. I cannot tell you I can do them but will try my best. The scores
are for you and I am trying to give you as much info as I can.
1. This will be the format for the scores sheet I will use. If you could
submit your scores as close to this as possible. The best way to submit them
is of course is just the summary sheet in CT or whatever program you
use.
CALL CLASS SCORE Q'S PTS DX
-----------------------------------------------------------------------
In this contest there are several and I do mean several classes you can
operate in. I will put you in any class you want to be in. If I get one
with no class listed or no power I will put the in the highest class I
can fine for you. All Single ops will go in the assisted class in that
case for an example.
Another thing which will save me a lot of time is where you put your
summary report. If you do not mind put your summary at the TOP of
your post. That way I do not have to look through a lot of stuff to find
the info I need
FINAL POSTING is another problem. When you see this post come out that is
what it means. You can send your scores to the reflector and let people
see them but I am not going to add them to the list. As I said this takes
a lot of time and really do not like having two going at one time. It does
amaze me that I will not get a score for over a week and post the final
and then get scores after that. Just so everyone understands this.
Breakdown sheet will also be done. I will assume that all that will be
needed on it is Q's and Multis.
Call 160 80 40 20 15 10
_______________________________________________________________________
WA4ZXA 100/20 300/12 250/100 400/240 120/128 10/5
Of course they will be put in a class.
Also all Multi-Op Stations need to submit a list of ops. I will also put
them on the sheet.
Now one of the most important things is
>> DO NOT POST ANY SCORES TO THE CQ CONTEST REFLECTOR!!!!!
This has been asked by the people who moderate this reflector. Please send
to me direct at floydjr at interpath.com or to the 3830 reflector. I believe
to subscibe to the 3830 reflector send mail to 3830-REQUEST at akorn.net and
put subscribe in the body of the text.
I hope all this helps in posting scores to go well. Thank all of you for
your thanks and all. I hope you understand I cannot reply to them all but
they are greatly appreciated. I have always felt that a person needs to
give back things to a hobby to make it work. That is all I am doing.

Thank you! I knew I had been a little out of touch lately with some
of the rule changes, but I couldn't believe the ARRL DX Test would
allow W to VE QSO's to count for any credit.
I'll never forget many years ago on 40 SSB a VO1 below 7.100 MHz
got so put out with the W stations calling on his frequency (saying listen
up, listen up) he yelled:
"Stateside guys, quit calling. We're on the same team!!"
He finally had to give up and work a few of the guys just so he
could work the DX calling him in the contest.

I just got off the phone with Billy Lunt at ARRL. The bottom line -- there
is no change. W-VE contacts don't count in either direction.
