Software Defined Radio Hack Chat

If you are into hobby electronics even for a short time, chances are you have at least one software-defined radio. From cheap switches originally designed for watching digital TV on a laptop, to specially built radio games with the ability to transmit like HackRF, SDR opened up many RF experiments. Prior to SDR, any change in range or mode will require new hardware; today, turning a new project is as simple as dragging and dropping a few blocks on the screen, and SDRs, which can observe huge stretches of radio spectrum for the slightest signal, are a boon to reverse engineering everywhere.

The handle of Harold Giddings, an amateur call sign KR0SIV, is corrosive, and it has entered the SDR in a big way. Between his blog, his YouTube channel, and its podcast, all flying under Signals everywhere banner, it covers the SDR community. Whether it’s satellite communications, aircraft tracking, amateur radio or even listening to rail operations, Harold has tried everything and has a wealth of wisdom for SDR to share. Join us as we discuss the state of the SDR ecosystem, which SDR to buy for your app, and even how to transmit with SDR (hint: you’ll probably want to ham license.)
