"The Far Sound" -- Bell System Video from 1961 -- Good Radio History (video)


This is a really OLD video, but there is a lot of great material here: 

-- Tubes.  (Valves or Thermatrons)
-- Coax.  
-- Frequency Division Multiplexing. 
-- Negative Feedback and the fight against distortion. 
-- Transistors and early experiments with semiconductors.
-- Fiber optics and Masers.
-- Satellite communications.
-- Early hopes for video communications.

The video is, by today's standards, extremely misogynist.  And the sound experiment with the poor woman wearing a male head was just weird.   But still, an interesting film. 

Thanks to Mark KM4GML for reminding us of this wonderful Bell Labs (AT&T) video archive.

    Very good. True, quite misogynist!
    Wow! Chet Huntley!
    "And with that, good night Chet, good night David!"

    The AT&T Tech Channel At https://www.youtube.com/@ATTTechChannel
    is replete with such goodies. And although the company is different now, it hasn't forgotten its past. Inside AT&T Labs, Bedminster, NJ you are greeted by a bust of Claude Shannon in the hallway.

    All destroyed by Judge Green. People don't even recall the name Bell Telephone Laboratories.
