Check 40 late at night....less rag chewers. I worked 15 countries on forty meters during the CQ contest couple weeks back in about 1 hr 45 minutes....it was good and my antenna was resonant on 10 meters only without the tuner. With my power level and less the stellar antenna system, if I Had planned to operate 40 and put up a wire or ? Antenna I think it might have netted more than 10 meters? (55countries). 12-15-17 have been open here, less it seems to me than a couple weeks ago but I've not been on as much. 20 seems weakest here.
Some of the rare expeditions are multi band operations...if I hear them on 10 Then I look for them on 12-15-17 many are on at the same times, the pile up seem smaller.
This morning as the sun came up so did Europe .... Noonish came S America Canada Iceland and the USA ....330 to 530 cst Japan , Alaska then a couple ZL-ZK. Japan was very strong....Australia New Zealand weak signals. No Tahiti or oceanic stations heard. Seems ZL-ZK guys should be stronger? I only listened on 10-12 no antenna. Yet for 15. Down.
