N3FJP is a suite of amateur radio software tools developed for logging, contesting, emergency communication, and station management. The package integrates with common shortwave radio interfaces and supports interoperability with popular logging standards used by ARRL, CQ Amateur Radio, and regional associations. It is maintained by an individual developer widely referenced in ham radio communities and intersects with many community projects and organizations.
N3FJP provides a collection of standalone applications and utilities aimed at amateur radio operators, contesters, and emcomm volunteers. The suite interfaces with hardware from vendors such as Yaesu, Icom, Kenwood (JVC Kenwood), and software ecosystems including DXcluster, Logbook of The World, eQSL, and Club Log. It supports logging formats compatible with ADIF, CABRILLO, and integration with third-party tools like HRD Logbook, DXLab Suite, WSJT-X, and Fldigi.
The developer released early versions in the 1990s coincident with the rise of Windows 95 and affordable PC-based logging. Over time, the suite evolved alongside milestones such as the adoption of ADIF by multiple logging projects, the emergence of packet radio clusters, and the proliferation of digital modes exemplified by PSK31 and FT8. The software has been discussed in publications and forums frequented by members of American Radio Relay League, Radio Amateurs of Canada, and international contesting bodies including IARU and RSGB.
The suite consists of several modules addressing separate tasks: contest logging, general logbook management, award tracking, and utilities for DXpedition coordination. Modules have been used in conjunction with event software for contests such as the ARRL Field Day, CQ World Wide DX Contest, NAQP, and regional competitions organized by entities like Pennsylvania QSO Party organizers. The projects have interoperability with databases and services maintained by eHam.net, QRZ.com, Ham Radio Reviews and aggregators like DX Summit.
Key features include multi-mode logging, real-time radio control using CAT protocols from manufacturers like ICOM, Yaesu (Vertex Standard), and Kenwood (JVC Kenwood), and export utilities for submission to contest sponsors such as CQ Magazine and ARRL. The applications support serial and USB interfaces common to FlexRadio Systems, Elecraft, and Kenwood transceivers, and integrate with station automation suites exemplified by MicroHam and Rigblaster. Logging capabilities include award chasing for programs like Worked All States and DXCC, and support for digital-mode exchanges used in ARRL RTTY Roundup and CQ WW RTTY.
Users of the software are active across forums, mailing lists, and clubs including QRZ.com, eHam.net, QRZ.ru, and regional amateur radio clubs such as Quarter Century Wireless Association and Northern California Contest Club. Operators participating in contest clubs and ARRL-affiliated groups often coordinate via web forums and social media groups linked to state and national organizations like American Radio Relay League and international bodies such as IARU Region 2.
The software has been employed at on-air events including ARRL Field Day, IARU HF World Championship, CQ World Wide DX Contest, regional QSO parties such as the California QSO Party and Pennsylvania QSO Party, and emergency drills organized by groups like ARES and RACES. Its use in DXpeditions and club multi-operator stations supports logging under high-rate conditions and post-contest submission workflows to sponsors such as CQ Amateur Radio and ARRL Contest Branch.
Documentation for the suite appears in user guides, forum threads, and articles on platforms such as QRZ.com forums, eHam.net reviews, and posts within Contest University presentations. Third-party tutorials appear on websites maintained by clubs like the Madison DX Club, Florida Contest Group, and in training resources produced by organizations such as ARRL and RSGB.
