I heard something this weekend at N5TW that I think must have been a 
recording of me played back over the air.  After one of my CQs ending with
"Norway Five Tango Whiskey," I heard my own voice respond with those 
exact phonetics.  But it started exactly after I stopped, and it 
wasn't like I only heard a portion of the "norway."  I can't swear that it
matched exactly the intonations, etc. that I used on that CQ, or that
it matched the voice keyer CQ.  It was reasonably loud.  If it had been an 
echo, it would have been delayed almost two full seconds.  I figured at the 
time that it was someone with a DVP recording my own voice and harrassing 
me.  (Loud W5 contesters seem to get harrassed at fairly frequent intervals 
during the contests, although it's usually carriers.)

But, I only heard it happen once.  So, who knows?
