The RF Noob
Learning RF from scratch — SDRs, amplifiers, and test gear. Long dormant but thorough.
A self-described noob’s documented climb through radio-frequency territory: HackRF and SDR dongles, spectrum analysers, FLDigi/SDRAngel/WSJTX software, and a long QRPLabs 10W HF amplifier series covering gain, linearity, input impedance, and IP3. The learning-journal format makes the RF concepts unusually approachable. The channel has been dormant for about five years, but the 73-episode archive is a complete beginner-to-intermediate RF course.
