RSGB 2021 Online Convention presentation - Software Defined Radio

Andrew Barron, ZL3DW
Andrew presented an entertaining talk about Software Defined Radio that re-evaluates what we mean by SDR. It covers the evolution from DSP and discusses the merits of hybrid SDR technology. He goes on to cover SDRs with multiple receivers, the limits of direct sampling, FFT and the panadapter, and multiple receivers. Finally taking a look at DFC (direct Fourier conversion) and some advancements for SDR transmitters. The talk is technical, but not too technical. No maths, (well not much), no software code, and no vector diagrams. It is suitable for those who want to learn more about Software Defined Radio, whether you already own one or not. It is not intended for SDR developers and experts.
