I have a couple of NESDR Smart dongles from NooElec [1], that have worked very well for me. I run them on a Raspberry Pi 3 and pipe audio output to my desktop or laptop with PulseAudio. Aside from SDR# on Windows and gqrx on Linux, there's also GNU Radio [2] and a variety of lightweight applications that can run on, let's say, a Raspberry Pi Zero [3]. Oona Räisänen has a fascinating blog that touches on digital signal processing as well, applicable to SDRs as well. Me? No ham license, but that may come someday.
