Intro to SDR Kits:

Software Defined Radio: $40ish SDR using a hacked European HDTV setup (RTL2832U). The chip has a feature where it can spit out the raw IQ data instead of the specific demodulated TV stream. It’s definitely hacky and it can’t transmit but it’s a relatively low cost intro into SDRs.
Adafruit SDR: Basic set-up from Adafruit that’s all contained in one easy USB dongle using the same IC as above.
Ossmans Kit: Not exactly a beginner’s kit in the sense that it’s cheap ($300 plus antenna) but probably one of the most full-featured starter’s out there sold by Mike Ossmann. He’s currently got a 9 video course available online to go with the HACK RF.
Mike Ossmans Video Course or he also teaches two day seminars on SDRs at security conferences across the globe.
