One control layer for your entire radio station
CAT4OM is a modern radio-control platform designed for amateur radio operators, station builders, software developers and automation enthusiasts. It places a dedicated service between radios and applications, translating different manufacturers and protocols into one consistent control model.
From a single transceiver to a networked multi-radio station, CAT4OM gives every connected application a clear, live view of the equipment. The service manages the radio-specific work—connections, commands, protocol translation, validation and state—while desktop interfaces, logging programs, dashboards and custom integrations connect as clients.
The result is a station that is easier to control, extend and automate.
What CAT4OM can do
- Control one or more radios from a central service.
- Read and change frequency, mode, VFO, split, PTT and other model-specific functions.
- Keep a secondary receiver or SDR synchronized through Radio Follower.
- Remotely power compatible radios on and off.
- Deliver radio-state changes to connected applications in real time.
- Allow several clients to monitor a station while coordinating which one may send commands.
- Connect compatible software through built-in Hamlib NET rigctl subset emulation.
- Provide a JSON WebSocket API for dashboards, integrations and automation.
- Support different radios and protocols through data-driven XML handbooks.
- Protect critical transmit operations with ownership rules and server-side safety mechanisms.
Built around the station, not a single application
Traditional CAT control often binds one program to one radio on one computer. CAT4OM separates the radio engine from the user interface. The service can continue managing the station while different clients connect locally or over the network.
The supplied CAT4OM interface is one possible client, not the boundary of the platform. The same service can also support third-party applications, remote panels, logging integrations, test tools and purpose-built station automation.

Multi-radio control
Organise radios into independent groups, combine different manufacturers and connection types, and let several applications share live station state without competing for the same CAT port.
Radio Follower
Keep a secondary receiver or SDR aligned with the main transceiver. CAT4OM mirrors confirmed frequency and mode changes while keeping transmission and potentially unsafe commands strictly separated.
Remote station and power control
Operate CAT4OM across the network and switch supported radios on or off through their CAT interface. Group lifecycle automation can bring a compatible station online and shut it down in a controlled order.

Architecture and real-time state
CAT4OM uses a service-first architecture, dedicated management and control channels, and live state distribution. Clients see one coherent model whether a radio is monitored through polling or native push events.

Radio compatibility and handbooks
Serial CAT, Icom CI-V, Expert Electronics TCI, FlexRadio SmartSDR and UDP-based interfaces can all sit behind the same control layer. XML handbooks describe the exact behaviour and capabilities of each supported model.

Integrations and API
Connect compatible software through the built-in rigctl interface or create richer integrations with the native JSON WebSocket API. CAT4OM is designed to become part of a wider station ecosystem.

Safety, diagnostics and reliability
Ownership coordination, transmit safeguards, reconnection policies, diagnostics and per-radio logs help keep complex or remote stations understandable and under control.

A platform that grows with your station
CAT4OM combines a strong central radio engine with replaceable clients, structured radio definitions and open integration surfaces. Today it can control, monitor and synchronize radios. The same foundation can support new protocols, new clients, new automation and broader station coordination over time.
Whether the goal is to operate one radio more cleanly or to build a complete networked station, CAT4OM provides one consistent place where radios, applications and workflows meet.
