The polar opening was also on 10 meter ssb/cw last nite with 9N7AA in Nepal, JT1CO in Mongolia and several HS hams in Thailand, 9v in Singapore, a half dozen Indonesians a 3W1 in Vietnam, a dozen central China hams and even some long path to Finland on 10 CW with amazing true 59/599 signals for over an hour and 45 minutes with all these occurring after 0200UTC and best of all no FT8 required.
In 48 years of 10 meter operation I have never heard Nepal nor Mongolia on any analog modes let alone them being on CW/SSB and only recently have I worked both of these countries on 10 meter FT8 which wasn't a real challenge but last nite on 10 cw and ssb it was for sure the best 10 meter I have experienced.
After working them on FT8 last week It was nice to do a Digital Detox and get away from FT8 and work Nepal and Mongolia on SSB/CW to confirm it wasn't a fluke.
My equipment was a K3s at just 12 watts into a 4 element OWA yagi at 30 feet for 10 meters.
