[CQ-Contest] Re: Weirdness, LDE

[zl1aih at ihug.co.nz]

In 1954, (while I was 4th op on a passenger ship, copying press, London 
Copyright Press or RCA, at 25 wpm each evening on the 8-12 watch), on 
one occasion I heard the text repeated - about 2 to 3 words behind.   This 
phenomenon lasted for about 5 minutes and then disappeared.  This was on 
12 mHz, a vertical antenna over salt water.  The repeated text was strong 
enough to be not only recognisable but confusing, to the extent that I was 
forced to delete several items from the ship's newspaper (draft copy)
Given the delay, this was no ordinary chordal hop or LDE.   I have not yet 
seen an explanation for this type of event, which lasted long enough for me 
to get the 3rd op to verify my log entry, which was most important.   
I had heard echoes before- up to a second or so, but nothing like this.

The ship's daily newspaper was 10 foolscap pages - on that day, it was only 
nine, and there were explanations to be made to the Master, and Chief 
Purser, and for my explanation, I needed all the help I could get.
