It was a pleasant surprise to have JL8GFB and JA8ISU answer my CQs this morning 1000-1010z -- a few minutes before my sunrise.Both had signals peaking 569 through some QRN. Both complained of QRM there from the "Dragon" jammer. I'm not sure if this is the earliest I've worked a JA, but it's nice to have the band open. 73/Jon AA1K
