About QSO Graph

Mission

QSO Graph is open amateur radio software for your station: logging, nets, awards, spots and your radio, in one place, on Windows, macOS and Linux, with the libraries and AI integrations behind them. Each tool does one job and stands alone; together they share ADIF and published interfaces, so an operator or a club can use the one that applies and add others later.

It started with the MCP servers, which let an AI assistant answer questions from an operator's own data: "Do I have any new LoTW confirmations?" "What's the solar forecast?" "What POTA spots are on 20m right now?" The products page lists what is available and what is coming.

The Name

A QSO is a radio contact between two stations. Graph refers to the network of connections between operators, bands, modes, and propagation paths. QSO Graph is the connective tissue between ham radio services and the tools operators actually use.

Author

Greg Beam, KI7MT — Advanced class amateur radio operator, software engineer, and builder of the IONIS-AI HF propagation prediction system. 49,000+ QSOs across all HF bands. Based in Idaho.

QSO Graph grew out of the IONIS-AI project's need to integrate with ham radio services for validation and analysis. Every QSO Graph tool is useful on its own: you don't need IONIS-AI to use QSO Graph.

  • IONIS-AI — Ionospheric Neural Inference System. Physics-constrained neural network for HF propagation prediction, trained on 14 billion amateur radio observations.
  • ionis-mcp — MCP server for propagation analytics using IONIS-AI datasets (175M+ signatures from WSPR, RBN, contests, and PSK Reporter).
  • ionis-jupyter — Jupyter notebooks for propagation research.
  • qso-graph-auth — OS keyring credential management for all authenticated QSO Graph servers.
  • adif-mcp — ADIF 3.1.7 spec engine — validation, parsing, enumerations, geospatial.
