PropagationStats

PropagationStats

Add PropagationStats to your ham radio site.

  

Radio Blackouts range from R1 (minor) to R5 (severe)

Solar Flux ranges from 50 (low) to 300 (high).  Sustained high values for SF indicates stronger ionization, hence higher MUF.  Values above 150 (sustained) are prime for HF.

K values range from 0 (low) to 9 (high) indicating degree to which propagation will be disturbed / MUF depressed by geomagnetic factors.  Low values are desirable.
