[Dx-qsl] RE: What is the correct ITU zone for Latvia?

[Phil Florig]

Hi Bill and group,

List at:
http://www.arrl.org/contests/announcements/prefixtable.html
However this does not break out the various zones for certain countries.

I asked a similar question before:

Subject: [Dx-qsl] Grid Sq to CQ/ITU zone converter

Hi all,

Don't know where else to ask this, so pse excuse the bandwidth.

Looking for a software or url for a program to convert
grid square/log-lat to CQ/ITU zone.

For example:

4K1D is Antarctica and no zones are indicated.
Qth is shown as 70-46S  11-51E
This converts to JB59WF
Now I need the zones.

I did find going to the link:
http://www.cq-amateur-radio.com/wazlist.html
that 4K1D is zone 36.

However I couldn't find R3RRC/ANT at grid EB90MA.

Tnx in advance for any suggestions.

DXView will do that. If you enter a gridsquare or latitude/longitude, it
will plot the location on a world map that optionally displays CQ zone
boundaries, or ITU zone boundaries.  DXView is free, and available via
www.qsl.net/dxview .

Phil, DXView will indeed show you the ITU zone or CQ zone for a
particular grid square:

1. click the Map panel's "World" button so that the world map is visible

2. enter a gridsquare designator in the Grid box and strike the enter
key - DXView will place a blue dot on the world map identifying that
square's location

3. in the World map window, click the "CQ Zones" or "ITU Zones" radio
button - DXView will draw and label the specified zones on the world
map. Note the zone containing the blue dot, and you have your answer.

Using this technique with gridsquare EB90ma, you will see the that CQ
zone is 12 and the ITU zone is 74 .

Unlike grid squares, neither CQ zone boundaries nor ITU zone boundaries
are geometrically specified, so a simple algorithmic conversion is not
possible. One must either populate a table for each grid square, or
digitize the zone boundaries and use pixel-flooding to determine the
zone enclosing an arbitrary location.
