    Erratum #1 (many thanks to Frank Donovan W3LPL): Marconi's 1901 experiment involved one way transmissions at approximately 500 kHz from Poldhu, Cornwall to
    his rudimentary receiver in St. Johns, Newfoundland. And Clifden was not a continuation of his experiments, it was Marconi's first successful commercial radiotelegraph operational capability
    that began initial 24x7 operations in 1907.

    Erratum #2 (many thanks to John Ackermann N8UR): Use of live music / orchestras in the early days of radio wasn't due to the technology as much as it was copyright and
    economics. The phonograph companies were afraid radio would put them out of business, so they refused to license broadcasters to play their records. That led to the live radio orchestras. Later the compulsory license system was introduced and the record industry had ASCAP and BMI as engines to collect royalties, so broadcasting records became OK. But that caused the unionized studio musicians to fight against the stations playing recorded music, because they wanted to preserve their jobs. The stations couldn't win.

    (A li'l Amateur Radio and all related History lol maybe), "The Man In The Moon", is now the CB operator down the street with a crappy linear amplifier between modulation resistor stripped radio and the wide banded incorrectly grounded wide banded antenna, probably and Antron 99.

    Interesting lecture but spoiled by ill mannered students who come and go as they please. I don't know how the lecturer is able to keep his cool.
