    Can I get a print of this? I think it would look good on my wall in my office

    i believe telstar communicated in the microwave, not the radio spectrum.

  • James Stratford

    Would the author object to me printing this for my father? He’s a life-long radio lover.

    We should take note that prior to 1890, in 1879

    transmitted morse code with it within 500 yard (460m) range.

    You guys entirely missed the step that made radio practical.  Edwin Armstrong took Deforest’s discovery (using the term loosely) and put it to use as an amplifier in the superhetorodyne receiver.  DeForest was charlatan..  Armstrong was the genius that made modern radio and TV possible.
