So many times there are short hop sporadic E-layer openings on 10 and 6 M and that is not related to the F-layer and the solar flux. There are a few months every year that this kind of propagation occurs. Even though double hop E- paths are rare they can happen. Just something that makes the 10 M and 6 M bands interesting. I even have worked what seems to be e- skip on 12 M a few times.
