Herb,
Of course the VI should be counted as DX. You are 1000 miles further from
the ConUS than me, and I count as DX (C6AGU), being only 200 miles from FL.
It is not logical that you should compete on the same level as the guys in
the middle of the country, with everybody all around them. But, on the
upside, you will be able to work me with ease!
73, GL and CU in the Contest,
George,

That's correct but under these rules, the VI is not DX and counts the same
as a W/VE two-pointer. Navassa which is certainly rare, especially on 160,
is counted as KP2. Desecheo KP5 is counted the same as KP4. Sort of weird
wouldn't you agree? This is unfair when VP2V on 5 miles from KP2 is
counted as DX. Also, all the rare DXCC US entities in the Pacific like
NMI, Wake, American Samoa, and Guam all count for Hawaii. The ARRL is set
in their ways and claims the 160-meter contest is supposed to be like SS
for 160. They only add DX contacts when ARRL President W0DX and VP2VI
demanded he should not be excluded from operating in a contest he
envisioned in the first place. The bottom line is that the statins in the
U.S. Territories cannot be competitive and are seriously discriminated
against by the Contest Committee who refuses to visit this issue. I
challenge you to look up the results over the past two decades. Stations
in the U.S Territories are never even mentioned no matter how well they
have done in the ARRL 160 contest.

Herb,
Correct me if I'm wrong but I thought I read the rules for the ARRL 160
and saw where US possessions can work US VE and DX?

Subject: Re: Topband: Polarization on 160m
So is the 70-year-old Collins 74A4 with its mechanic filters and single
conversion method. Many times you could just roll the IX into a deep hole
with the bandpass control and the signal would pop out of nowhere. Wish I
still had mine to run comparisons. I have now a modern (expensive) Flex
6600M that allows true dual diversity with 2 RX antennas with separate RX
audio in each ear. I will try it out in the ARRL 160 contest although the
ARRL has the VI as non-DX which is always has been a real bummer.
