Log4OM is a Windows-based logging application for amateur radio operators that integrates logging, contesting, station management, and digital mode interfacing. It connects to radios, rotators, and digital modes while supporting DX Cluster aggregation, satellite tracking, and award management. The software appeals to operators active in contesting, DXing, and awards chasing across global amateur radio communities.
Log4OM provides a graphical user interface for amateur radio logging that interfaces with transceivers, rotators, and digital mode programs. It supports integration with popular transceivers such as Icom IC-7300, Kenwood TS-590, Yaesu FT-991A, Elecraft KX3, and FlexRadio Systems, and coordinates with station automation projects like Ham Radio Deluxe, DM780, WSJT-X, Fldigi, and JTAlert. The application facilitates awards tracking for programs such as DX Century Club, Worked All States, Islands on the Air, CQ World Wide, and IOTA, and can import/export logs using formats like ADIF, CABRILLO, and CSV.
Log4OM includes logging, contest support, award tracking, QSL management, and cluster connectivity. It implements CAT control protocols compatible with vendors including Icom Incorporated, Yaesu, Kenwood Corporation, Elecraft, and FlexRadio Systems while supporting rotator control protocols used by RTL-SDR projects and commercial controllers. The software integrates DX Cluster networks such as DX Summit, Packet Radio networks, and remote spotting systems used by operators in ARRL DX Contest, CQ WPX, and IARU HF World Championship. Other features include rig control, map plotting with overlays referencing services like Google Maps, OpenStreetMap, and satellite tracking tied to orbital data from NORAD and Celestrak.
Development began as a community-driven project influenced by earlier logging suites and station automation environments. Its creator contributed updates reflecting changes in transceiver firmware from manufacturers including Icom Incorporated, Kenwood Corporation, and Yaesu following trends set by platforms like Ham Radio Deluxe and N1MM Logger+. Over successive versions the project adopted modern Windows practices seen in applications from Microsoft Corporation and incorporated digital mode interoperability inspired by WSJT-X and Fldigi development. Contributions and issue tracking have occurred via community channels frequented by contributors associated with organizations such as Radio Society of Great Britain, American Radio Relay League, and regional clubs like Radio Amateurs of Canada.
Operators use Log4OM for everyday logging, contest entries, and award chasing across regions including North America, Europe, Asia, Oceania, and Africa. It runs on Microsoft Windows and interacts with USB-to-serial adapters following standards from vendors like FTDI and Prolific Technology. The application exports ADIF files compatible with global logging services such as eQSL, LoTW, and club logbook services provided by organizations like Club Log. Integration with mapping and satellite services allows coordination with networks such as AMSAT and logging for events like IOTA Contest and satellite operations supported by amateur organizations including AMSAT-UK.
Log4OM has been discussed among operators on forums and mailing lists associated with groups such as QRZ.com, Reddit (subreddit: r/amateurradio), eHam.net, and in publications like QST (magazine), RadCom, and CQ Amateur Radio. Users compare it with competitors including Ham Radio Deluxe, N1MM Logger+, DX Labs Suite, and Logbook of The World tools. Community contributions, translations, and plugins have come from volunteer maintainers often connected with local clubs such as Quarter Century Wireless Association and international bodies like IARU and IARU Region 1.
Security considerations include managing network connectivity to DX Cluster servers and remote-control interfaces that may use TCP/UDP services similar to those used by TeamViewer or AnyDesk for remote station control. Users are advised to handle credentials used for services like LoTW, eQSL, and club logins securely, and to apply Windows security practices recommended by Microsoft Corporation and cybersecurity guidance from organizations such as NIST and ENISA. Privacy considerations include the sharing of QSO data with online services and consent norms promoted by associations such as ARRL and regional regulatory bodies like Ofcom and FCC.
