Quick question here...

I've read about LDE a number of times and have even heard Art Bell talk
about it on Coast To Coast.

I've been thinking that it might be a product of the electronic equipment
itself, rather then any kind of outlandish atmospheric/propagation
condition.

My question... Has LDE ever been noticed or logged prior to the days of
solid state and computer chip rigs ??? I'd love to know the first known
observations of this phenomenon.


I've read that LDEs were first observed during the ionospheric reasearch of
the 1920s.



Any help on this question would be enormously appreciated.


Very long delayed echos, on the order of a few minutes, have also been
claimed. One theory has it that there's an alien repeater in lunar
synchronous orbit.
