The autumnal equinox (September 22 at 2044 UTC) is a little over two weeks away. Fall is always a great time for HF DX, when the sun casts an even face over the northern and southern hemispheres. If this is the peak for cycle 24, although solar activity is weak, this may be the best time for enjoying HF propagation for some years to come.
