SDR (Software Defined Radio) receivers are radios which have had some of their traditional components such as modulators, and tuners replaced by software and programmable chips in a very small circuit. Those who want to dip their toe in so to speak, not spend a lot and find out it isn’t that interesting to them. This article is for people brand new to SDRs who are unsure of the best place to start.
