I pulled my hair out setting up my Yaesu 450D to run WSJT-X on Win 10 without a dedicated USB interface but it's up and running and I'm making contacts with FT8. What I don't understand is how to log those contacts electronically. I have just set up eQSL and LOTW accounts but don't know how to get the info from WSJT-X to those. I have confirmed a few contacts on eQSL but have zero contacts in LOTW. Some questions I have: 1. Do I have to hit the "log QSO" in WSJT-X after every contact made or does the program do that automatically? I think WSJT-X saves these in a text file but haven't found it yet. 2. I see some people are have WSJT-X exporting their logs to HDRLOG. What's the advantage of HDRLOG?
