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
