Well, when the signals go over the poles they get cold and sometimes freeze up. (hi hi) Joe W4JSI

I don't live far from you and despite having directional antennas (including a 5 element monobander on 20 meters) I too have a lack of over-the-pole Q's in my log compared to non-polar paths. Generally speaking, I think part of the HF polar mystery is the shorter window of opportunity we have to work those paths compared to others during certain times of the year. In winter, the W1-to-Japan path sees less solar radiation than in summer so the MUF peak in winter doesn't seem to last as long on the mid to upper HF bands. On the lower bands, it's more an absorption issue and that's controled mainly by sunlight. The polar ionosphere is also more sensitive to magnetic storms, but there are many more quiet days than there are disturbed so this is probably not as big a factor as we think it is the majority of the time. As far as the DX you find easier to work, a lot depends on the global distribution of the electron content in the ionosphere. The high concentration of electrons at low and mid latitiudes would make it easier to work the countries you mention on the mid to upper HF frequencies. It's interesting to look at an MUF map to see how the MUF falls-off with electron content with a peak near the equator to a low at the poles. This tends to be true regardless of where we are in the 11 year cycle. You can see one of these maps at: http://www.spacew.com/www/realtime.php As others mentioned, propagation software can be very useful as a guide to determine the best times to work Japan. But keep in mind that the predictions are based on statistics and the ionosphere can vary by the minute. It does not react to small daily variations in the 10.7cm solar flux. Best Regards...
