I was using a 3-element SteppIR at 60ft. With the condx like they've been lately, I think it would be possible to work all over east Asia and Pacific if guys are active out there and there are decent antenna and power on both ends.

Now you're talking. Working JA on 10M sounds like something I'd like to try soon.
With the restricted space many JA's have to deal with, 10M Yagis are a viable alternative for them.
Good going.
