Since the sun's radiation creates and maintains the ionosphere, sudden
variations in this radiation such as those caused by solar flares can
affect
the performance of radio systems. Sometimes these natural changes are
sufficient to induce large transient currents in electric power
transmission
grids, causing widespread power outages. Lightning is known to cause
substantial heating and ionization density enhancement in the lower
ionosphere, and there are indications that ground-based HF transmitters,
including radars and strong radio stations, also modify the ionosphere
and
influence the performance of systems whose radio paths traverse the
modified
region. Perhaps the most famous example of the latter is the "Luxembourg"
effect, first observed in 1933. In this case a weak Swiss radio station
appeared to be modulated with signals from the powerful Luxembourg
station,
which was transmitting at a completely different frequency. Music from
the
Luxembourg station was picked up at the frequency of the Swiss station.

Yes, but still nothing to do with LDE's. The Luxembourg Effect is
something
totally different.

The 'Luxembourg effect' has nothing whatsoever to do with LDE's.

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.
