[Dx4win] Prefixes/Zones for Spotters

[Megin Murphy]

I would like to filter the spotters to include only US spots.  I found the
field under the Packet 1 tab for Prefixes/Zones for Spotters but when I
enter the zones 1 through 6 in every format I can think of, they don't
filter actually, all of the spots turn gray.  What format should the zones
be in?

Thanks,
Megin, K5IJ
