Plain-language answer: ALE channel prediction estimates which programmed HF channels are most likely to support a link before or alongside on-air sounding.

Why operators care

Predictions can shorten the search, but automatic link establishment becomes stronger when recent sounding and link-quality history are available.

How to use it well

Program legal, mission-appropriate channels, keep station clocks and addresses correct, and compare predictions with measured link-quality data.

The common mistake

Assuming the predicted best channel eliminates the need for sounding or monitoring.

Operating boundary

Predictions, reports, schedules, and mode descriptions guide a decision; they do not override current regulations, equipment limits, exact station conditions, or what the operator verifies on air.
