Connects Claude to 175 million aggregated HF radio propagation signatures from WSPR, Reverse Beacon Network, contest logs, and PSK Reporter spanning two decades. You get 11 tools that query SQLite datasets for band openings, solar flux correlation, path analysis across frequencies, and dark-hour propagation patterns. Answers questions like "when is 20m open from Idaho to Europe" or "how did the February 2026 geomagnetic storm affect propagation" without writing SQL. Designed for amateur radio operators planning contacts, analyzing propagation conditions, or correlating solar activity with band behavior. Download bundles range from 430 MB to 15 GB depending on whether you want contest data only or the full WSPR and RBN archives.
