Long delay echos
Mailing list: <GQRP.yahoogroups.com>
Just seen the link to
the long delay echos
from Peter
Brogl, DK6NP on the
Southgate
Amateur radio website:
http://www.southgatearc.org/news/december2010/long_delay_echoes.htm
I've
not yet seen anything about the power
he used or details showing if
the echoes spaces were EXACTLY the
same on each transmission. A
detailed
comparison between the
transmitter
and echo keying envelops
may
confirm that they really came from
DK6NP's
transmitter and not some
elaborate hoax. If genuine, surely this is a
remarkable
and tangible
example of this very odd (and rare?)
phenomenon.

Ian, G4JQT

At the peak
of recent sunspot cycles it was
not that unusual to hear
echoes
on 10m from signals that had gone
around the globe both ways
even several times. One could certainly
envisage
occasions when signals
get
trapped between some ionospheric
layers
and eventually "escape"
back
to earth - like a very extended chordal
hop.
