There is good reason to believe that while marconi developed the

invent it."
Reginald Fessenden invented the electrolytic detector which is
probably the 'liquid diode' mentioned above."

My mistake Jim. The key point is that Marconi developed a way to detect
(demod) RF whereas Tesla may have been among the first to generate RF.
I
think it is safe to say Marconi perfected wireless transmission of
telegraph
signals. Thanx for the correction on Fessenden's liquid diode. I
recall
reading that early watt-hour meters were electrolytic devices. Not sure
how
they worked, though. Maybe someone can help.

I would suggest you read the Tesla book I mentioned and find out what
really happened in regards to Marconi. It's very well covered. Marconi
lost the major patent law suits to Tesla until the U.S. government in a
time or war.....

It's in the book. :)



The REAL battle came later....between Edison and Westinghouse, and in the
end, it was influenced very heavily by ( of all things ) the Electric Chair.
