That was back when the 'L' beacon (302kHz)
was still morse code, now it's a DGPS reference.

Ever heard a LDE?

They amaze me, what is happening to cause that very strange phenomenon?

I don't think so, but have heard the 'flanging' type sound
when signals from long and short path mix on fifteen meters.

Yes, when the signal arriving at the antenna has chosen two separate
paths to reach that antenna ... very recogniseable audio phenomenon ...

But, LDEs, when there are seconds of delay, sometimes MANY seconds, and
which does not relate to them reflecting off the time it would take them
to reflect off any known astrological bodies ... spooky! When you hear
your own transmissions repeated to you, seconds later, if on SSB as a
side signal to the other party ... AMAZING!

Almost an argument for them reflecting off some alien spacecraft! ROFLOL

Since you seem to have some background, let me pose a question to you,
in my "crass manner."

Have you noticed that the nitwits here don't realize a proper antenna,
with good matching, feed, height, length, etc. will make a poor receiver
out preform a VERY high priced receiver with a poor antenna?

And, don't you think someone should begin a thread on that and suffer
the arrows? ROFLOL

Would it have been better if I would have said with a quality receiver,
and a PROPER ANTENNA system, you can detect rf of a cricket fart, from
the USA and which is generated in Australia? ROFLOL

Better to have an excess amount of signals for your cheapie to sift through than
having no signals to emphasize the futility of expense on that top notch unit.
You can obtain pre-selectors and attenuators for just about any radio, but if
there isn't anything coming into the shack, you're simply SOL.
Preamps without signals only make the hash louderg

I'd say, accurate appraisal ...
