Having worked LU and CX on 2 meters SSB (100 watts 7 element beam) without any ionospheric skip in the strange ducting FAI mode that is at time formed by the magnetic field at the equator, i say that anything is possible. But the idea of a multiple moderate angle skip with so many hops around the world and twice is IMHO really all that probable.

You can listen to it here.  It is so strong that you won't believe that is
really the echo.  I send two dits and hear two dits come back.

It appears this was from 1997 - I posted about it here:

I remember hearing similar echos on my 75 meter signal during a California
QSO Party when I was operating at K6NA's QTH back in 1987 or 1988.

For the first time,
I heard my echoes on topband, yesterday morning starting around 05 UTC.
They lasted for at least 1 hour, with some OFF-periods in between.
I had to quit at 06 UTC. (still 1 hour before surise)

The echoes were loudest on the short Beverages (<60m long) heading N/S
NE/SW and several dB lower on the NW/SE Beverage. (about 130m long).
The Tx setup is modest with Elecraft K3/100 and inv L at 15m height,
sloping down to 11m.

Only DX heard that morning was USA (typical condictions) so I wonder what
else does hearing echoes indicate?
