Re: Topband: Echo on 160m yesterday morning

This is interesting. I recall a discussion here about very long LDEs awhile back. IIRC, it was suggested that perhaps the magnetosphere and the Van Allen belts might be involved, rather than the much closer ionosphere. I heard a double echo on 75m last year. I heard his direct signal which was

Andy, There was a passenger on an airliner that took photographs of a very large Aurora at that time. . One of the photographs was shown on TV -ABC World News. It is likely that the Aurora sparked all these events. I have noticed that there appears to be a link between the start of

Re: Topband: Echo on 160m yesterday morning

I think this form of ducting takes place way above the layers of the atmosphere where weather happens. In my experience the magnetospheric ducting is normally localized in impact. If this was really happening in multiple places around the world at the same time on this occasion then I think

I have heard echoes of my own signal under some circumstances too. More often on 80M but a couple times on 160M. Often in the hour before dawn. These echoes were also heard on other stations within a few hundred miles, especially ones to my north. For the 160M echoes, some stations in W1 were

Your transceiver switching may not have been fast enough to catch the echo the first time around. On Sun, 5 Feb 2017 11:21:51 -0800, Tree wrote: Yup - pretty crazy. Or space aliens were messing with me. On Sun, Feb 5, 2017 at 9:51 AM, k1fz
