We are working on the algorithm, conditions shown here may not correlate with real conditions. The best check is always to power up your HF rig and listen on every band to be sure!

GRAPHICAL SUN DATA HISTORY

PROPAGATION BASED ON WSPRNET* (ALPHA)

Probability of QSO on 2m between NA and NA is 3%
Probability of QSO on 4m between EU and EU is 45%
Probability of QSO on 30m between AF and EU is 100%
Probability of QSO on 40m between NA and OC is 6%

* Propagation probability based on data from WSPRnet (Weak Signal Propagation Reporter Network) Spot Database
