EA4K

EA4K is an open-source software publisher focused on amateur radio utilities, best known for KLog, a cross-platform logging application that helps licensed operators record and manage QSO contacts across VHF, UHF, HF and digital modes. Typical use cases include real-time entry of call signs, frequency, mode and signal reports during contests, automatic award tracking for DXCC, WAS and WAZ, export of ADIF and Cabrillo files for submission to clubs and regulatory bodies, and integration with online services such as QRZ, eQSL and LoTW for confirmation and statistics. Because KLog maintains a local SQLite database, operators can work offline from a summit, island or field day site and later synchronize data when back online; the program also supports rig control via Hamlib, allowing frequency and mode to be read directly from transceivers, and it offers customizable labels, filtering and search so that hawks chasing rare entities can instantly see which band-slots or modes are still needed. As with most amateur radio software, the interface is keyboard-oriented to keep hands near the rig, and the logging window remains compact so it can sit beside digital-mode decoders or panadaptors. EA4K’s KLog is available for free on get.nero.com, delivered through trusted Windows package sources such as winget that always fetch the latest release and can be installed individually or batched with other applications.
