Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@rsba1-mcpread the current frequency and mode from the rig"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
rsba1-core
Pure Python implementation of the Icom RS-BA1 V2 protocol stack — control IC-705, IC-9700 and any CI-V transceiver over the network. No Icom binaries required.
What is this?
Icom's RS-BA1 software runs on Windows only and is closed-source. This project reverse-engineers the protocol and provides a pure Python replacement that runs anywhere Python runs.
Tested on: IC-705 (E2E verified 2026-08-18)

Quick Start
pip install "rsba1-core[mcp]" # MCP server needs fastmcp; plain CLI: pip install rsba1-core
export RADIO_HOST=192.168.0.31
export RADIO_USER=radio_user
export RADIO_PASSWORD=your_password
python -m rsba1.mcp read-freq
python -m rsba1.mcp set-freq 7074000Platform Support
Platform | Network (radio-link) | Serial | Mailslot / CivCtrl.dll |
Linux | ✅ pure Python UDP | ✅ | ❌ Windows-only |
macOS | ✅ pure Python UDP | ✅ | ❌ Windows-only |
Windows | ✅ pure Python UDP | ✅ | ✅ legacy backends |
The default radio-link backend is pure Python UDP — no Icom binaries, no
DLLs, no pywin32. The Windows-only backends (--backend mailslot, CivCtrl.dll)
live behind optional [windows] extras and are guarded so they never break
imports or test collection on Linux/macOS. Serial support needs pyserial
(pip install "rsba1-core[serial]").
