Win4Icom

Win4Icom is a Windows-based software utility that enables computer control and remote monitoring of Icom amateur radio transceivers and receivers via the CI-V communication protocol. It is not an official Icom product; it is developed by independent contributors and is widely used by amateur radio operators to streamline rig control, logging, and automation.

Key features include real-time rig control (frequency, mode, filter settings, and tuning controls), management of memory channels, and the ability to operate with other software through virtual COM ports. The program can log QSOs, export ADIF files, and automate common tasks with scripts or macros. It is designed to work with a range of Icom models that implement the CI-V interface and can support multiple radios connected to a single PC via appropriate USB-to-CI-V interfaces.

Typical deployment involves a USB-CI-V adapter connected to an Icom radio and a PC running Win4Icom alongside other ham software such as logging or digital-mode applications. The software communicates with the radio over the CI-V protocol to send and receive commands and data, while users configure the interface and model-specific settings in the program.

Community and licensing: Win4Icom is typically distributed through community-maintained websites or forums and is offered as freeware or shareware. Documentation is provided by the developers, and support is primarily community-driven.

Limitations and compatibility notes: Not all Icom models support every feature, and some functionality depends on the radio's firmware and CI-V command set. Users should verify model compatibility and driver requirements before use.
