About Ham Stats¶
Ham Stats is a product of the IONIS Project — the Ionospheric Neural Inference System. It publishes propagation reports generated from measured amateur radio observations, not modeled predictions.
What This Is¶
Every number on this site comes from a query against a ClickHouse database containing 13+ billion amateur radio propagation spots. The database runs on a self-hosted Threadripper 9975WX (32 cores, 128 GB DDR5, RTX PRO 6000 96 GB) with 3.7 TB of NVMe storage for ClickHouse data. No cloud services. No third-party APIs. No subscription fees.
The data comes from four independent networks:
- WSPR (10.8B spots, 2008–present) — weak-signal beacons at ~200 mW, measuring the propagation floor
- Reverse Beacon Network (2.18B spots, 2009–present) — automated CW/RTTY skimmers measuring real operator signals
- PSK Reporter (~26M spots/day, live since Feb 2026) — FT8/digital reception reports from operator software
- Contest Logs (195M QSOs, 2005–present) — SSB/RTTY contacts logged during major HF contests
Solar indices (SFI, Kp, SSN) are sourced from NOAA SWPC and GFZ Potsdam, joined to every spot at 3-hour resolution.
The IONIS Project¶
IONIS (Ionospheric Neural Inference System) is a PyTorch model trained on this dataset to predict HF SNR from geographic and solar features. Ham Stats is the public-facing reporting layer built on top of the same data pipeline that feeds IONIS training.
The IONIS model and all supporting infrastructure are open source: github.com/IONIS-AI
Infrastructure¶
| Component | Hardware | Purpose |
|---|---|---|
| ClickHouse database | Threadripper 9975WX | 13B+ spot storage and query |
| Live collection | 9975WX (systemd) | PSK Reporter MQTT, solar updates |
| Model training | Mac Studio M3 Ultra | PyTorch / MPS backend |
| Site generation | 9975WX (cron) | Query → Markdown → MkDocs |
Site content is regenerated every 3 hours from live ClickHouse queries.

The logs were speaking for decades, but nobody was listening. Now we're listening.
