One of my winter projects should be to find out how to use LOTW. I see Southgate News has a link to a guide. I must read it! Although I use eQSL, I am way behind, so need to update things.
LOTW seems the way to go in future. I may transfer some of my old QSOs when I join. I can't do them all as this could take days and days!
