Propagation

This page shows long term predictions of the the Link Reliability from Pretoria on the HF bands (80m to 10m).

The predictions update every hour on the half hour.

Note: To view the latest information you have to refresh the page every half an hour or so.

The Link parameters are:

- 100 W transmitter

- A dipole antenna, 18 m above ground

- 6 dB Signal-to-Noise in a 2100 Hz bandwidth (39 dBHz)

- Quite rural Atmospheric Noise

New data will be uploaded every week although predictions are valid for about a month.
