It used to be homebrew ham gear meant something simple. A couple of active devices that could send CW. Maybe a receiver with a VFO. But only the most advanced builders could tackle a wide range SSB ...

We are entering a new era of radio technology. A new approach to building radios has made devices like multi-band cell phones and the ubiquitous USB TV receivers that seamlessly flit from frequency to ...

Traditionally, working with RTL-SDR required a deep understanding of radio frequency (RF) principles and a significant investment in sourcing compatible components. This complexity often posed a ...

No doubt most tech and electronic enthusiasts have encountered buzz around SDR, software-defined radio, and asked themselves “what’s the sudden big deal,” if the technology existed for decades? The re ...

Chances are, you’ve actually used one without realizing it. I’m referring to a software-defined radio, and it is the design that most — if not all — modern radios, including automotive and home models ...

Like almost everything else in electronics, radios are becoming processors with software that communicate via a small amount of RF I/O circuitry. Surely, then, the rise of software-defined radio (SDR) ...

There is a new breed of RF receivers known as software-defined radios, and they are revolutionizing the way in which people listen to shortwave (SW) radio, or indeed any form of radio broadcast. SDRs ...

If you've never heard of software-defined radio, that may be because some might liken it to outlaw pirate-radio; it's a wild-west wireless device which will, in theory, receive or transmit radio data ...

Are you following this? My sense of the direction of wireless products is that practically everything is becoming a software-defined radio (SDR). The highest-volume wireless products, cell phones, are ...
