Re: [BVARC] Echo on receive DX.

[James Burrough via BVARC]

 I had a similar experience Friday just before the CQWW SSB got started. I 
heard echoes on two New England stations that indicated a long-path/short-path 
combined signal on the stations. Saturday, during the contest, I had contact on 
10-meters with a Hong Kong station where he was S3 on short-path when I first 
heard him. He mentioned he was pointing his beam to the U.S. via long-path. I 
turned the beam 180 degrees and completed the QSO with him at S9.

meters.
Remember, it was only some signals. lol, so it wasn't the radio. 73

Re: [BVARC] Echo on receive DX.

I remember working from Houston as WA5KHM, a VU ( India) at around 9PM CST,
on CW 15 meters in about 1965 when I was 15 years old.  There was a W5???
Corpus Christi ham had his antenna on a Commercial broadcast tower so it
was up maybe 100+ feet elevation.  He was too far for groundwave and too
close for direct skip.  The Corpus W5 worked the VU first, and I worked the
VU after the Corpus W5.  The VU and the W5 sounded very echoic.   For the
Corpus W5 I don't know if I was hearing Long Path followed by a second Long
Path?  ...or was I hearing atmospheric scatter as the first arrival from
Corpus, and Long Path as the second arrival.  But I heard an approximate
1/7 second between sigs which corresponds well to Earth circumference. I
remember the echo made it very hard to copy.  It seemed like *an echoed dit
filled in the blank space after the dit before it*. It muddled up a word
real good!

Figuring at ~18wpm a dit is very close to exactly the time (Morse baud =
WPM/2.4)... and it takes a signal to go around the world about one DIT time
at that WPM. (25,000miles/186000miles/seconds ~1/7s ).  I don't remember
but I'm guessing most likely I engaged in something like a 15WPM to 20WPM QSO
so it fits. I had an old WW2 oscilloscope and don't remember if I had it
hooked up, but then I could have seen if there was another blip from 2nd
pass. I seem to think I did, but I told this story so many times when I was
a youngster, it may have turned into a "fish story" so I'm not sure. LOL

 Has anyone seen a long path blip come around the world more than once?
