Thanks for the response. If it is an LDE, it is awfully consistent. I can hear it all the time now on 80m, at least for the past three days.

There were some notable one's reported in the last WPX contest. One happened to me. On 40 meters I was working a Guam station from the east coast, and had been hearing short echoes for a while. I sent my contest exchange, the other station QSL'd it and sent his end of contact CQ. That was followed by the LDE of my contest exchange in its entirety, which he QSL'd again. Which left ME a bit confused until I figured out what I had heard. Wish I had a recording of that. Easy to know it was my exchange because WPX exchange has a serial number in it. At this point, I'd guess that was delayed by better than two seconds, but could not say for sure. That would be some number of times going around the earth. Over the years I have heard the once around the earth delay many times. That one takes about the time of a sent dit, and is very confusing if you are using QSK. These can be very strong, and have heard it using the FT1000MP barefoot. Most often whatever path it is lasts 3-4-5 minutes and fades away. 73, Guy. ----- Original Message ----- From: "Sverre Holm" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]>; <[email protected]> Sent: Tuesday, June 15, 2004 3:16 AM Subject: RE: [Elecraft] 80m "Reflector" problem > > I made several recordings ( I can forward them) and it looks > > like the signal is always approximately 1.52 seconds delayed > > and lasts about 1 second.
