Reading the display
The global view shows the current DX Index and tomorrow's forecast for each available band. Regional views show the strongest band and WSPR activity for each active intercontinental corridor.
The regional activity labels use the same thresholds as dx.py:
| WSPR spots per transmitter | Activity |
|---|---|
| 50 or more | Excellent |
| 25–49 | Good |
| 10–24 | Fair |
| Below 10 | Poor |
The data is produced by HB9VQQ's HF DX Index. It is based on actual WSPR reception reports rather than a propagation model.
