Digital Transmission Primer with Ward Silver

Posted by Kirk Harnack [TWiRT]

TWiRT 231I’ve often said, “This here digital’s the coming thing.” We all know it’s here now, and here to stay.

Ward Silver, N0AX, is a teacher, a contributing editor to the American Radio Relay League (ARRL), and author of the book, “Ham Radio for Dummies,” as well as many others. We’re getting a lesson from Ward on Quadrature Amplitude Modulation (QAM) as well as I & Q signals. Symbol constellations, predictive coding - we’re diving right in.
