#N1MM Logger+
N1MM Logger+ is a free contest logging program that is widely used on HF and VHF. It supports a very large number of contests, keeps your station details with each contest, and can export a Cabrillo file for submission. Because many operators use it, the way it writes entry information and exchanges is a frequent topic of questions. Articles under this tag describe how to set it up, how to export a Cabrillo file and what to check in the result. Menu names can vary between program versions, so the posts keep their steps general and point you to the program’s own documentation.
