so ive been going back and forth on this for a while now and cant really settle on a workflow that doesnt drive me crazy. right now i use WSJT-X for FT8 obviously, and i have it set up to log to Log4OM which works fine most of the time. but then when i actually do a contest i switch over to N1MM and everything is in a different place and i end up with two separate logs that i have to merge after the fact which is kind of a pain.

the adif import into Log4OM from N1MM exports has been hit or miss for me, sometimes the band gets imported wrong or the mode shows up as something weird. not sure if thats a Log4OM thing or how N1MM is exporting. anyone else deal with this or have a cleaner way to do it. i dont want to abandon N1MM for contests because honestly nothing touches it for that, the band map and the rate display and all that is just way better than anything else ive tried. but the post-contest cleanup is getting old

yeah this is basically the same situation i was in for like two years. what i ended up doing is just accepting that N1MM is the contest logger and Log4OM is the shack log and treating them as separate things. then after every contest i do a careful adif export from N1MM, open it in a text editor real quick to check the MODE field looks right, and then import. the band issue you mentioned is usually because N1MM uses FREQ in MHz and sometimes the adif parser in Log4OM gets confused if the frequency is slightly off for whatever band - like if you were on 14.074 it should map to 20m fine but ive seen it choke on 60m entries before.

the other thing worth checking is whether your WSJT-X is also trying to log to N1MM over UDP at the same time. if you have that enabled and you're not running a contest it can sometimes create duplicate or weird entries in N1MM that then get exported later. i just disable the N1MM UDP connection in WSJT-X when im not contesting and life got a lot simpler after that

honestly i just use N1MM for everything including regular logging and gave up on Log4OM. probably not helpful but the merging thing sounds like more trouble than its worth to me. N1MM's regular logging mode is fine enough for day to day stuff and it handles the WSJT-X UDP feed pretty reliably in my experience
