HF propagation analytics. 175M WSPR/RBN signatures, band openings, solar correlation.
IONIS (Ionospheric Neural Inference System) is an open-source machine learning system for predicting HF (shortwave) radio propagation. The datasets — curated from the world's largest amateur radio telemetry networks — are distributed as SQLite files on SourceForge.
The server publishes 13 tools. What each one is for:
list_datasets — Show available datasets with row counts and file sizesquery_signatures — Flexible signature lookup — filter by source, band, grid, hour, monthband_openings — Hour-by-hour propagation profile for a path on a specific bandpath_analysis — Complete path analysis across all bands, hours, months, and sourcessolar_correlation — SFI effect on propagation — grouped by solar flux bracketgrid_info — Maidenhead grid decode with solar elevation computationcompare_sources — Cross-dataset comparison (WSPR vs RBN vs Contest vs PSKR)dark_hour_analysis — Classify paths by solar geometry — both-day, cross-terminator, both-darksolar_history — Historical solar indices for any date rangeband_summary — Band overview — hour distribution, top grid pairs, distance rangecurrent_conditions — Live propagation forecast — SFI, Kp, solar wind, band outlook, POTA/SOTA tipsget_version_info — Service version + upstream dataset version (fleet identity attestation)Compare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.
Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.
