I’ve often said, “This here digital’s the coming thing.” We all know it’s here now, and here to stay. Perhaps we’d be well-served to understand some techniques for transmitting digital information over radio frequencies (RF). Ward Silver, N0AX, is 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.
