rsba1-mcp
Enables AI agents to read frequency, mode, and signal meter, as well as set frequency and control PTT on Icom IC-705/9700 and CI-V transceivers over the network using the RS-BA1 protocol.
README
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
export RADIO_HOST=192.168.0.31
export RADIO_USER=linnan
export RADIO_PASSWORD=your_password
python -m rsba1.mcp read-freq
python -m rsba1.mcp set-freq 7074000
MCP Server (for AI Agents)
python -m rsba1.mcp # starts MCP server on stdio
Available tools: read_freq, read_mode, read_smeter, set_freq, ptt, get_status
