First off, I was wrong (also rather rude) to criticize Joe for not
sending the "normal" zone for Wisconsin and I apologize for that. I
didn't realize it then, but there are several instances where ITU zone
borders don't match at all with state boundaries. I was wrong, period.
The feedback I have gotten thus far from the ARRL says that I should
adhere to the official ITU boundaries.
In my case, the ITU zone boundary does not even match the U.S./Mexico
country border. See
The reason this topic has a familiar ring to it is because it surfaces
over and over again without a firm resolution. I can find comments well
over ten years old on various web sites that question just what a
participant should use in any ham radio contest that calls out ITU
zones. Here are three links that all originate from the ARRL that all
say a different thing:
1. The July 7, 2010 ARRL Contest Update suggests that IARU participants
might consider the RSGB ITU zone list at
http://www.rsgb.org/spectrumforum/hf/hfawards/witu.php , which simply
specifies that all of Arizona is in ITU zone 6
2. However, the June 10, 2010 version of the ARRL Contest Update
references a link provided by K1DG that is the same official ITU map
that I referenced above, clearly showing the southern Arizona border
region to be in zone 10.
3. The archived ARRL link identified by N4OGW/5 (
) just a few reflector posts ago shows a different zone for Arizona
depending upon whether the station is east or west of longitude 110 but
says nothing about the southern border region.
Contrary to your comments, the situation is not as simple as just
copying what is sent. It also applies to sending the proper zone;
otherwise people could just pick one of their own choice. I should be
held accountable for adhering to the rules and sending my proper zone
designator, or risk disqualification if I don't. The rules very plainly
tell me to use the official ITU zone boundaries and that puts me in zone
10, but nobody ... even the ARRL ...expects me to actually use zone 10
in my exchange. Do I use zone 10 for the potential advantage it gives
me within the rules, or do I take the safe route by (ironically)
disobeying the rules and use zone 6?
I just find all of this to be needless ambiguity, and for me a bit
frustrating that nobody is willing to make an official declaration on
the issue after all these years. I'm pretty sure if I checked carefully
(more carefully than I did before shooting off my mouth about WB9SBD)
that I could find similar situations elsewhere, including internationally.
