Re: [Elecraft] OT: LDE defined
I agree, Doug. I've been a ham for 35 years now and have experienced the round the world trip signals on CW during most good propagation when using QSK. It's interesting, but not that rare, especially when you are using high power and good directional antennas. 73, Tom Childers Radio Amateur N5GE Licensed since 1976 QCWA Life Member 35102 ARRL Life Member Retired Professional C# Software developer http://www.n5ge.net On Fri, 7 Jan 2011 14:14:24 -0500, DOUGLAS ZWIEBEL doug...@gmail.com wrote: What is being described does not sound like the classic definition of an LDE.

I've heard myself many times on 80m CW but not the higher bands where one would expect to hear your long path signal come back. It's still a mystery.

Re: [Elecraft] OT: LDE defined
I also have witnessed signal delays on 80 meters. Not the long delayed echo type but the shorter duration echos. It could be a magnetic field anomaly that produces this effect. If we hear the echo I suggest we check out the solar flux, K, A indexes of the time period and record them for future reference. It is an interesting thing to hear and I have heard them a few times.

These delays were the classic 140ms or so for a single hop round the world. My best DX, working myself on longpath... But the LDE's referred to on 80m are more usually several seconds. There was an extensive article in QST a few years ago from a USA amateur who had experienced these. You can easily explain the round-the- world ones (and you don't need high power) but there is no logical explanation for the very long delay ones. I don't expect to hear these myself with 5W and a short longwire... 73 Dave G3YMC http://www.davesergeant.com __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] OT: LDE defined
At NY4A multiop, probably in the ARRL DX some years back, on 40 meters, with the antenna a monster 5 element full spaced quad on a 220 foot catenary, I sent TEST NY4A NY4A, and after a very slight pause heard clearly at S8 or S9, TEST NY4A NY4A. I was sure someone was just trying to interfere on the frequency, but it happened consistently. I finally sent a miscellaneous string of random dits and dahs from the paddle, with no spaces, for about 5 seconds. I heard the string start up during the QSK, and it continued for another 2 seconds or so after I let up. By that time I was on the speaker, and I had witnesses to what happened. We all settled on LDE and got back to the contest. The LDE got weaker and weaker (but not quicker or slower) and faded out in about ten minutes. So nobody has to convince me about LDEs any more :) 73, Guy. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
