Conditions 00-10MHz:Fair
Conditions 10-20MHz:Poor
Conditions 20-30MHz:Closed
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 23cm between EU and EU is 30%
Probability of QSO on 6m between EU and EU is 17%
Probability of QSO on 10m between EU and AF is 31%
Probability of QSO on 20m between OC and AS is 7%
Probability of QSO on 30m between AS and EU is 5%
Probability of QSO on 40m between OC and AS is 56%
