Just to clarify: I only have the .QSO files from back then, and need to convert them to .ADI format. Pete, K2PS Hello all, I was an NA user back in the early 90's and have a bunch of .QSO files that I'd like to move to DX4WIN in preparation for LoTW. Is there a conversion routine out there that would help me do that? Thanks es 73, K2PS
