Hello, Rainy." - In 1892, ignorant of
the wireless inventions of the past 60 years, Nathan creates an
electromagnetic induction wireless telephone and demonstrates it
to his friend Rainey Wells. A few years later, Nathan develops
a superior wireless telephone that uses natural conduction through
the earth and water.
Stubblefield was experimenting with ground radio since 1882, but
did not patent his developments until much later. Credible
witnesses saw his ground radio experiments in action during this
time frame, establishing the historical priority of Stubblefield.
While Marconi could barely send telegraphic "dots and dash" signals
with great difficulty through a static-filled medium, Nathan Stubblefield
had already transmitted the human voice with loud, velvet clarity.
Others would adopt and implement the Collins system (Fessenden,
DeForest, Bethenod, Braun), but none could duplicate the Stubblefield
System.
Stubblefield researched "Magnetic Waves" and developed
several systems which did not use ground terminals for exchanging
signals. Long distance wireless telephone communications were his
aim. Many imagined this to be radio as we know it, but several
features of Stubblefield aerial are distinctive and different.
Mr. Stubblefield reasoned that, since electrical waves traverse
the whole earth, it might be possible to send signals to distant
places. These ground-permeating natural electrical waves might
serve as carriers for the human voice. The ground would act as
both power generator and signal conductor.

1882 - Transmitted audio frequency electromagnetic signals
1885 - Transmitted the Human Voice, using his induction coil transmitter
1892 - First to Broadcast Human Voice, using his wireless telephone attached
to a landaerial - First Wireless Telephone Broadcasting Demonstrations [Voice]
1898 - May 8 -- Patent Wireless Telephone Transmission Coil

P.S.:"Tesla was among the curious onlookers in
attendance at Stubblefield's 1902 wireless demonstration in
Philadelphia."
