Harold Giddings created "Signals Everywhere", a website with multiple publications (including a podcast!) about SDR. In this episode, we talk about how Harold first discovered software radio, learned about it, and some of the topics most interesting to him in the SDR community right now.
I’ve been into radios and scanning in general since I was a young kid playing with a basic 10 channel crystal controlled police scanner. On and off from there I’d use a hand held scanner to find interesting signals although most of the time that’s all it was. Something interesting that I couldn’t do anything with.
A few years ago in an IRC server I used to hang out on someone approached me about something called an SDR, it was a DVB-T TV tuner stick whose driver was hacked to allow wide band reception with a water fall display. These were crazy inexpensive although not of the best quality at the time.
With several of them in hand I saw an entirely new world of radio, I was able to access radio bands and signals I never could have before and all that with the added benefit for a large waterfall display.
I became obsessed about learning how these devices worked and about radio communications in general.
I went on to obtain my Extra class Amateur Radio license and founded Signals Everywhere, a community where I could both share what I've learned with the community while learning from them in the process.
Signals Everywhere is about exactly that, learning from others and teaching what you know. Growing as a community and expanding your knowledge in ways you never knew.
