Using version 7.0.8. I have had several complete contacts that failed to log. When I looked in the VarAC Log file for the most recent failure I see messages like: 01/04/2023 22:50:04 - Unable to log QSO with XXXXX ,missing information (I changed the real call to XXXXX for this example) Upon further research, I noticed that RST-S was not filled in during the contact, even though I sent a report (just before a QSY request). When I entered the RST-S number I was then able to log the contact using the LOG button (ADIF file and UDP to my logbook). Even though it didn't have the RST-S number (maybe that is the bug), it seems like it should have logged the contact anyway? Or provided an on-screen error message? 73 Bill WT0DX
