- Other major problems were that changing the operating frequency was a lengthy and complicated process, and unlike a spark transmitter, the carrier signal could not be switched on and off at will.

- Radio experimentation at the University of Minnesota, initially using spark transmitters that could only transmit the dots-and-dashes of Morse code, began in 1912, conducted by Professor Franklin Springer.
- For a time Fessenden continued working with more sophisticated high-frequency spark transmitters, including versions that used compressed air, which began to take on some of the characteristics of arc-transmitters patented by Valdemar Poulsen.
- Smith was licensed on 3 July 1914 and one month later, he received a message from the Marconi spark transmitter at Poldhu in Cornwall, being sent to London, on the eve of the outbreak of war.

- In 1904, Danish inventor Valdemar Poulsen had introduced the arc-transmitter, which, unlike the intermittent pulses produced by spark transmitters, created steady signals that could be used for amplitude modulated ( AM ) audio transmissions.

- Fessenden's request for a faster, more powerful unit was assigned to Ernst F . W . Alexanderson, who in August 1906 delivered an improved model which operated at a transmitting frequency of approximately 50 kHz, although with far less power than Fessenden's rotary-spark transmitters.
- This was followed by tests that included, in the fall, Eugenia Farrar singing " I Love You Truly " . ( Beginning in 1904, the U . S . Navy had broadcast daily time signals and weather reports, but these employed spark transmitters, transmitting in Morse code ).
- He was one of the first researchers to realize, from experiments like the above, that the existing technology for producing radio waves, the spark transmitter, was not usable for amplitude modulation, and that a new kind of transmitter, one that produced sinusoidal " continuous waves ", was needed.
- When Reginald Fessenden contracted with the company for a steam turbine, Weagant applied for a job, and from 1908-1915 worked at Fessenden's National Electric Signaling Company's station at Brant Rock, Massachusetts, working on the design of the 100-kilowatt spark transmitter for the United States Navy's first high-power station at Arlington, Virginia.
- In September 1915, Reynolds, then living in Minneapolis, Minnesota, was issued his first license, for an amateur radio station with the call sign 9WH . This initial station employed a spark transmitter that could only transmit the dots-and-dashes of Morse code, moreover, with the entrance of the United States into World War One in April 1917, all civilian radio stations were ordered to cease operations for the duration of the conflict.

( Marconi withdrew from the Exposition when he learned de Forest would be there ).
