We usually think of the RTL-SDR as a low-cost alternative to a “real” radio, but this incredible project spearheaded by [Rodrigo Freire] shows that the two classes of devices don’t have to be mutually ...

Software-defined radios are great tools for the amateur radio operator, allowing visualization of large swaths of spectrum and letting hams quickly home in on faint signals with the click of a mouse.

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) ...

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 ...

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 ...

Earlier this month, Radio World reported on the grant of a construction permit for a new LPFM station in Colorado Springs, Colo., which was awarded to the Colorado Society of Wireless and Broadcast ...

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 ...
