Great examples of poor directional calling. What the ops usually mean as opposed to USA ONLY is NA ONLY (USA, Canada, Mexico, etc.). Also JA ONLY usually means, JA, JT, HL, UA 9/0, and other Asia.

I imagine almost any location will have areas where propagation only exists for a short time to those areas and other areas where they have propagation over a much longer time period. For instance, DXpeditions to VU4, VU7, BS7 etc. only have a short time when they can work this part of the USA. They probably can work JA's for half a day on the same band. It would make sense for them to call "USA only" during that hour or so and work JA's when they don't have limited openings to this and other areas. DXpeditions to the mid-Pacific have propagation to EU on the low bands till the sun rises in EU. They have propagation to the USA during part of this time but they continue to have propagation for another 4-6 hours to the USA. After the sun rises in USA they still have propagation to JA. It would make sense to work only EU till they lose propagation, then USA till they lose propagation, then work JA's for a while. Some past DXpeditions didn't do this. Clipperton Island is in an interesting location. It appears it's in the same region that has Mountain time in the USA. The sun rises there before it does in California. So on the low bands they would want to work both USA and JA's till their sun rises. So maybe non-directionsl CQ's are the best bet under those circumstances. It definitely takes some planning and study of propagation charts to make most DXers happy. 73, Zack W9SZ On Sun, 16 Mar 2008, Peter Dougherty wrote: > At 10:52 PM 3/16/2008, Charles Harpole wrote: >> Many recent DXpeditions have, in my opinion, over-studied the data to serve >> "under served areas", have propagation charts, and be extra aware of their >> "important position" as the only (last?) hams to be at that locale.
