VOACAP Predictor (public)

Run path-specific HF reliability predictions by grid square and UTC window. This tool uses the same live engine behind the API and converts results into practical operator decisions (best band now, next best windows, and hour-by-hour matrix).

Engine status: Checking… Loading status endpoint.

Path setup

Manual entry.
Click map to set RX location
Map loading…

Quick pick common targets
Then refine with search or manual grid if needed.

Find RX by country, city, or landmark (instead of typing grid).
Global grid map
No place selected.
End hour is auto-computed so matrix always covers 12 consecutive UTC hours.
Bands
Ready.
Hint: hover any field, option, or button for quick guidance.

Operator decision panel

Best band now
Run a prediction to populate.
Best UTC hour
Engine-picked top window within your range.
Reliability
0–100 modeled reliability score.
Confidence
Thresholds from runtime settings.
Next best window UTC hour Reliability
Run a prediction to see alternatives.
How to use this output
  • Pick the best band/hour pair first, then keep one backup from “Next best window”.
  • If confidence is low, verify quickly on-air before committing a schedule.
  • Re-run when Kp or X-ray conditions change suddenly.

Interactive propagation map

Map overlays update from your latest VOACAP run. Choose a band and hour to visualize changing path reliability.

1) Run prediction
Generate the 12-hour matrix first so map layers have path data to render.
2) Pick band + hour
Use the controls below to inspect modeled reliability hour-by-hour.
3) Compare observed
Blend real-world spots with model output and review Obs-Model deltas.
Feature toggles Turn capabilities on/off for the operating style you want right now.
UTC hour: —
Keeps the map moving through the 12-hour window. On by default: CAT frequency changes auto-switch map band. Rig band: unknown
Traffic region filters + priority alerts Filter map traffic by region and trigger alerts for priority regions/modes.
