With 100 000 QSO uploaded to LotW, I have an almost 26% hit rate. That was only about 18% a year or two ago. Still I wish there were more users to the LotW system. That might be achieved if the ARRL would finally open up the system for other awards (WAZ, IOTA etc).
And a more flexible user interface where you could edit previously uploaded contacts. That way we’d be able to deal with the busted call issue in an elegant way.
