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.
it goes without saying but Please on future productions make the slides populate the entire screen then overlay if desired the speaker in a corner D'oh ... as is its impossible to read most slides
(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. KD8EFQ/73
"This is what you call an rtl dongle. eight bucks on ebay." --- This is exactly how adversarial malware is spread sneaker net style right through our most important institutions. I hope he doesn't do any work for our Gov't.
These lectures are a great resource. Thanks so much for putting them up on TH-cam.
Instant thumbs up for using kilometre.

In the near future, the internet and radio will indistinguishable from one another.

Not sure why you need to try and feel superior in TH-cam comments.... maybe get a dog? It is clearly in intro class, you miserable twat-waffle

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.
Stop using metric system.
