I found this little gem that VE3DVY put together on Field Day and using N1MM:
This video is a great introduction to logging with N1MM. It only goes over using N1MM while logging and leaves out all the N1MM configuration info that you don’t need to know for field day. If it still seems too complicated, don’t worry, it’s not. We’ll walk you through it this weekend when you show up to operate. You are going to be there to operate, right?
Probably the most important and hardest thing to remember is pressing CTRL+o and entering your callsign when you sit down at the station. This signs you into the software and will let everyone else on the network know that you’re on that particular station and it assigns your callsign (or name if you don’t have a callsign) to each log entry. When you are finished operating at that station, it’s always a good idea to press CTRL+o again so the prompt is waiting for the next person who comes by to operate and so that they won’t log QSOs under your call.
See you all at School Street Park in Agawam this weekend!
