[450] Echoing signals.

[Thomas & Patricia Moore]

Ok, but that explanation may be a bit too complex. Years ago, while tuning on an empty freq. in preparation for a special event ( either the Queen's golden jubilee or Olympics or something), heard a faint echo of myself on 20.  A day of exceptional propagation, I figured I was hearing myself 'bounce' around the globe.

This may be of interest to Bob because we've had several conversations  
about it.

"Another interesting phenomenon was an “echo” on both 160 meters and  
80 meters of about 1/3 second delay which happened sometime in late  
1995. After checking some QST articles and inquiry to the ARRL tech  
department, the phenomenon matched a situation called a long delay  
echo (LDE) where a “wormhole” in the earth’s magnetic field developed  
and my signal went out along magnetic field lines and bounced off the  
ionosphere in the southern hemisphere and came back. It lasted for  
about half an hour and disappeared! Weird huh?"

Anyway, both Bob and I -- perhaps other guys on the reflector have  
experienced a similar effect on some of the higher bands like 10  
Meters. We've been going around about the possible reason(s) for quite  
a while. The above *may* be a possible explanation.
