[CQ-Contest] Echo

[Tom Osborne]

A couple of times this weekend while on 10 meters, I heard myself
after I let the mike key up.  Twice I heard "5903" and it was my
voice.  I read somewhere that a big station used to hear his
signal bounced off the moon, but he was using a huge 4 antenna
stack.  I'm only using a 2 element monobander at 30 feet and 100
watts so no way do I think I could do that.  Could I hear myself
LP or something?  Did anyone else notice that phenomenon?  73

If the voice sounded like you (and you had no RIT on), that rules out
an EME echo (which would have a doppler shift, and sound "bassy").

The delay is too long for an "around the world" path (around 140msec,
I think).

Over the years I hear tales of LDE's, ("Long Delayed Echos"), so maybe
it's one of those?
