Amateur Extra Lesson 5.2, Display Devices, 11th Edition

Here’s your video introduction to Section 5.2, “Display Devices,” in the 11th Edition of the ARRL Extra Class License Manual for Ham Radio. Topics covered include light-emitting diodes, liquid-crystal displays, and charge-coupled devices. Note that the old manual had material about vacuum tubes that is no longer a part of the examination. So, I’ve included the vacuum tube material as bonus material at the end after the credits.

    I downloaded the new Extra Class question pool and was surprised at the changes.
    A lot of the technical information was familiar, but some was very new.
    The changes I have seen from the time I received my Scout Radio Merit Badge till now is fantastic. Vacuum tubes, then transistors, then chips and now SM electronics and optical cables. Miniaturization has made a major impact on both laboratory and field science, and has made a lot of testing gear much more affordable. I am a retired chemist/botanist.
    Thank you for your videos. They have helped me quickly review and learn newer material.
