Ham Stats¶
HF propagation reports generated from real data — not models, not opinions.
Every number on this site comes from measured amateur radio observations: WSPR beacons, Reverse Beacon Network skimmers, PSK Reporter decodes, and contest logs. Solar conditions are correlated with actual signal measurements, not theoretical predictions.

Band Activity (Last 24 Hours)¶
Which bands had propagation in the last 24 hours, based on spots from all sources. RBN archives lag ~24 hours; zeroes indicate no data in the window, not band closure.

IONIS Predictions — KI7MT (DN26) Contest Paths¶
V20 model predictions for the current solar conditions (SFI 116, Kp 2.33). Which bands can work which continents right now?
| Destination | 10m | 15m | 20m | 40m |
|---|---|---|---|---|
| Europe (JN48) | CW | CW | CW | CW |
| Japan (PM95) | CW | CW | CW | CW |
| S. America (GG87) | CW | CW | CW | CW |
| Africa (KG33) | FT8 | FT8 | FT8 | FT8 |
| Oceania (QF56) | FT8 | FT8 | FT8 | FT8 |
| Caribbean (FK68) | CW | CW | CW | CW |
Mode thresholds: SSB ≥ +3 dB, RTTY ≥ -5 dB, CW ≥ -15 dB, FT8 ≥ -21 dB, WSPR ≥ -28 dB. Predictions update every 3 hours with current solar conditions.
About This Site¶
Ham Stats is generated every 3 hours from a self-hosted ClickHouse database containing 13+ billion amateur radio propagation observations — one of the largest curated datasets of its kind. No cloud services. No third-party APIs. Every query runs against data we collected and maintain.
The data comes from four independent networks, each measuring a different layer of HF propagation:
- WSPR (10.92B spots, 2008–present) — the SNR floor at minimum power
- Reverse Beacon Network (2.25B spots, 2009–present) — CW/RTTY measured signals
- PSK Reporter (356.2M spots, live since Feb 2026) — FT8/digital operational contacts
- Contest Logs (234.3M QSOs, 2005–present) — the SSB/RTTY ceiling at contest power
Solar indices (SFI, Kp, SSN) are joined at 3-hour resolution so every propagation measurement has its solar context.
This site is a product of the IONIS Project — the Ionospheric Neural Inference System.
The logs were speaking for decades, but nobody was listening. Now we're listening — and we're publishing what we hear.
