Have Clark on a couple of bands now. Always fun to get western China. He’s in the same call zone as JT. Although, he is much easier to get. Seeing his antenna setup and QTH pics on his QRZ page, it’s no wonder :-).
He hangs out on 15 and 17m a lot during our evening hours--if you have not worked him. Last night he was easy. He has confirmed via LOTW within a short time on both calls.
