September 2017: Ionospheric Propagation Predictions
 

Solar activity in September will be at very low levels, so propagation will not be excellent, especially on the highest bands. The progressive rise of the dark hours will favor the lower bands. From mid-month onwards there will be the effects of Equinox, so the long path propagation conditions with Oceania will be great.
