There are a couple of guys on 3840 kHz that experience LDE often.

I, myself, was experiencing a mild echo where I'd catch the last
second or so of my last transmission on one night on 75m. Other
signals on the band were frequented with echoes too. It was pretty
bizarre.

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.

Any help on this question would be enormously appreciated.
