The special event certificate is loaded with visual information about Father Jozef Murgaš' invention and achievement.

Morse code signals. He called the latter the musical
wireless telegraph system. Instead of dots and dashes,
the system sent two equally timed tones of different
frequencies. One tone represented dots, and the other
tone represented dashes. The result was the ability to
communicate using Morse code at a rate of 50 words
per minute, nearly three times faster than the Marconi
system.
By 1905, Murgaš was ready to demonstrate his
system. In the preceding months, a partner, Universal
Aether Telegraph Co., financed the construction of two
enormous towers. Constructed of pine and steel, these
towers stood 150 feet high. Each tower resembled a
closely spaced pair of oil drilling rigs with a bridge
between them at approximately 100 feet. One tower
was constructed on a hill behind the Sacred Heart
Slovak Church in Wilkes-Barre. The tower dwarfed all
other town structures. A second tower was constructed
just south of Scranton on a hill in an area now known
as East Mountain.
On Nov. 23, 1905, representatives of the Navy,

University of Pennsylvania, Universal Aether Telegraph
Co, the Catholic Church, and the mayor of WilkesBarre joined Murgaš and telegrapher Gideon Shadle of
the Scranton Times in the radio room connected to the
tower in Wilkes-Barre. At the Scranton tower, several
were present, including representatives of Scranton,
the county, United State Department of State, and the
Universal Aether Telegraph Co, along with the mayor
of Scranton.
At 2 p.m., the telegraphers sent messages back and
forth between the mayors at a rate of 45 words per
minute. At the time, this was considered a significant
achievement. Remember, in the early 1900s, everything
about radio was new. Successful transmission of
signals across an ocean didn't necessarily mean signals
would travel as far over land. A demonstration of radio
signals from an aircraft wasn't made until 1910.
In the early portion of the 20th century, Morse
code was well established and was a reliable way of
