Guess I had better try a 10m repeater tomorrow for @hamchallenge HC09. My closest is ~80 miles away, a distance at which I have never had a 10m QSO. Given the conditions I'm half wondering if I should try for a repeater in eastern US/Canada, which just seems insane.
Yep, as I thought, the best 10m repeater for me to try is on another continent. While I didn't join in, I heard a UK-Jamaica QSO this afternoon on VE3MMX, Ontario Canada.
@hamchallenge HC09 still open, may try again from home another day.
