Propagation Experience

Unlike my trip to the Falklands in April, I fully expected to get good propagation from Ascension. Bearing in mind its geographic location and my carefully chosen time (at the peak of cycle-23. Propagation has lived up and definitely exceeded anything that I could have hoped for. I have had at least some propagation every day, although two were quieter than the others.

The propagation had following characteristics:

o The first two nights produced pure, strong evening TEP to Europe starting at 20:00 on the dot in the evening. There was nothing during daylight hours that I noticed and I was wrongly convincing myself that I wouldn�t be seeing any during my stay.

o For the first two nights, the propagation shifted from Europe to the Caribbean at around 22:30 in the late evening (though European signals didn't die away).

o Sunday, onwards I did not see any early evening European TEP  but the late evening Caribbean TEP occurred every evening while on the island.

o Sunday onwards, propagation shifted strongly to morning TEP starting at about 11:00 and dying at 13:00. On these days I did not see any early evening TEP to Europe.

o On two nights, the TEP turned into long-path openings that lasted for over two hours. This surprised me, as I thought that long-path openings were transient in nature. Signals were strong and had no flutter of any sort, almost like Es openings.

I am forced to wonder why this major shift from early evening to morning TEP happened? What triggered it? I guess it happens all the time. Late night long-path openings seemed to be independent of whether there was either a morning or early evening TEP opening earlier. When I was experiencing the long path openings Jose, EH7KW and Nick, 5B4FL experienced them as well. Were they experiencing a weaker version of what I was hearing? It was certainly different as neither heard FO or BV.

Anyway, all this is summed by Neil, G0JHC by saying in an e-mail while I was on Ascension: "I bet you wish you lived there" Boy, he could be right!
