Conditions 00-10MHz:Poor
Conditions 10-20MHz:Closed
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 70cm between NA and NA is 18%
Probability of QSO on 2m between NA and NA is 3%
Probability of QSO on 6m between OC and OC is 51%
Probability of QSO on 80m between SA and OC is 35%
Probability of QSO on 630m between OC and NA is 16%
