Where to start learning SDR (Software Defined Radio)?

Question

Radio communication

With the software, it seems to be clear, SDRSharp is recommended in many places.
But I find it difficult to choose iron. The course of electrical engineering has long been forgotten as unnecessary, I myself am more of a programmer than a hardware worker.
Can you recommend guides or specific models?

Answer 1
