About
N1MM Logger+ is a free, fully-featured ham radio contest logging application and the most widely used program of its kind worldwide. Designed for amateur radio operators participating in contests, it supports all major operating modes including CW (Morse code), SSB phone, RTTY, PSK, and WSJT digital modes. The software covers hundreds of supported contests spanning HF, VHF/UHF, DX, DXpeditions, and QSO parties, with dedicated setup workflows for each contest type. Key features include a streamlined QSO entry window, programmable function key message macros, customizable keyboard shortcuts, audio setup, multiple window skins, and DX cluster integration with live spot reporting. N1MM Logger+ supports direct radio interfacing for frequency and mode control, and accommodates everything from single-operator stations to fully networked multi-computer, multi-operator club setups. A built-in User Defined Contest (UDC) editor lets operators create custom contest definitions beyond the extensive built-in list. External UDP messaging allows integration with third-party software and accessories. The program is continuously developed and updated, with an active community forum, comprehensive documentation, how-to videos, and a dedicated support system. N1MM Logger+ runs on Windows and is completely free to download and use, making it the go-to choice for both new and experienced contesters.
