Real-time propagation tool goes online

The RSGB report Jim Bacon G3YLA has developed an online tool to show
near real-time critical frequency over the UK and the predicted
maximum usable frequency over different paths

The site description says

The plots are designed to show the near real-time evolution of the
critical frequency ( foF2 ) of the F2 layer as measured by the
international network of ionosondes. The display system is set up to
process data from the USAF ionosonde at RAF Fairford in
Gloucestershire on the Cotswolds.

These data are automatically decoded from ionograms and where
conditions do not allow a value to be determined automatically, a gap
appears in the graph. The displays depend upon the data being uploaded
from the measurement station and therefore depends upon many
operational factors outside our control. Outages are usually of short
duration, so keep checking periodically if data is missing.

The purpose of these graphs is to allow radio amateurs to use this
professional ionosonde data to improve their understanding of radio
propagation conditions heard on the air in relation to actual measured
conditions on the ionosphere, as they happen.
