    Invented the Danish?

    the Danish really did not invent the Danish. It was invented in Russia, 1n 1848. chah!

    KIDS AND SERIOUS EXPERIMENTERS WERE USING SPARK GAP AND CRYSTAL SETS PRIOR TO 1909. THEY USED THEIR NAME OR INITIALS FOR 'CALLS'

    And before that

    There was the "Victorian Internet" where landline telegraphers would rag chew and gave us many of our abbreviations and prosigns. Who's to say who started it all?

    What about Nathan Subblefield??????

    Who is the radio ham? Stubblefield, Fessenden, Edison, Marconi or Dessau OZ9DES.

    Nathan B. Stubblefield (1860 - 1928)

    Stubblefield was self educated by reading publications.

    His devices were based on audio frequency induction and later on audio frequency earth conduction.

    His devices were designed for induction and not radio frequency radiation.

    His "wireless" telephony in the 1880s was an acoustic telephone.

    Scientific American magazine of 1880s carried articles about wireless that describe induction systems not radio frequency generating systems.

    In 1892 Nathan B. Stubblefield made the first broadcast by voice using a wireless telephone attached to ground electrodes. This was voice transmission by induction and not radio radiation.

    In 1894 Sir Oliver Lodge demonstrated the transmission of damped high frequency radio waves but that system could not carry voice messages or music. It was Morse code only.

    In 1 January 1902 Nathan B. Stubblefield demonstrated voice and music transmission over a half mile radius through earth conduction and not by radio frequency radiation in courthouse square in Murray, Kentucky, USA.

    In Washington DC on 20 March 1902 Nathan B. Stubblefield transmitted voice and music over a third of a mile from the steamer Bartholdi to shore by using wires in the water.

    On 30 May 1902 in Philadelphia, Mr. Nathan B. Stubblefield transmitted voice and music over a half of a mile.

    In June 1902 in New York City the Stubblefield system was less successful due to electrical interference from the wide use of electricity in the form of alternating power.

    The Stubblefield system used large circular conduction coils to transmit voice frequencies. This was earth conduction and not by radio frequency radiation.

    In 1907 Stubblefield used a 60 foot coil to reliably cover a quarter of a mile.

    On 12 May 1908 Stubblefield received a US patent 887,357 for Wireless Telephone using his voice frequency (audio) induction system. These were not voice modulated HF radio waves.

    Nathan B. Stubblefield is described as the father of broadcasting.

    He did create interest in this field of science.

    His system of broadcasting was through induction in the ground.

    Radio broadcasting is regarded as radio frequency radiation in air.

    His experiments were discussed in scientific journals.

    Stubblefield promoted stocks in the Collins Wireless Telephone Company.

    Stubblefield resigned as a director in December 1911 in the Continental Wireless Telephone and Telegraph Company because of what he said was fraudulent stock promotion practices. Other principals of the company were later convicted of fraud.


    In 1886 Reginald Fessenden did scientific work with Thomas Edison.
    On 24 December 1906 Reginald Fessenden made a high frequency voice broadcast using a rotary spark gap transmitter.
    Fessenden ceased radio research in 1911 after his dismissal from National Electric Signaling Company NESCO.

    Some early inventors are best described as scientists.

    Other early inventors might be described as business people.

    Others are best described as ham radio or amateur radio operators and experimenters

    The radio amateur is described as the person who explores radio for the love of it without commercial or other intent as we know amateur radio today.

    The first amateur radio operators (hams) made up their own call signs because there were no regulations when radio was first invented.

    The first radio amateur will be some one more than 100 years ago who started when only Morse code was able to be transmitted and received and who later obtained an amateur radio license (or other proof) for his earlier amateur radio spirit.

    The 1890s saw reports of Guglielmo Marconi and his success in transmitting and receiving messages using wireless. Although Marconi is not known to hold an amateur radio license he is on record as having identified with amateur radio when he insisted on visiting an amateur radio exhibit in the USA. He said “they are like me” when others with him were directing him to the profession radio exhibits (“no they are hams come here and see the professionals”).

    On this basis one might say that in Marconi is the spirit of the love of the exploration of radio and that Marconi is the father of amateur radio because those radio hams that followed did so in the spirit of adventure and exploration which was lead by world press reports of what the young Marconi had done. In this case the first radio amateur had no call sign because he was the first. He is therefore unique because from him come all the aspects that would be known as radio.

    No earlier radio explorer can be said to have captured world newspaper reporting that resulted in citizens around the world building their own ham radio stations (as Marconi had done) at a time when no radio regulations existed. The first hams (radio amateurs) wanted to copy what Marconi had done. That is why they did as he did. They built their own transmitter and receiver, got on the air and experimented with like minded citizens across the world. Like Marconi these were not scientists but ordinary people that were inspired by what Marconi (a wireless enthusiast) had done.

    Einar Dessau 1892-1988 of Denmark holds the title to the first (not scientist, not business man) but amateur radio communicator (experimenter) to transmit and receive a VOICE transmission at the age of 17 years. He has identified himself as having the amateur radio spirit by holding the amateur radio call sign OZ9DES.
