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 ...

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 ...

[regveg] was looking for a way to receive signals outside the normal 64-1700MHz range his TV tuner software defined radio dongle can get. After finding a few $100+ upconverters on the Internet, he ...

The frequencies employed by law enforcement and first responders can be a source of vital information in emergency situations but you can’t tune in using any old radio. But rather than spend big bucks ...

I want to get just a little technical this week and talk about how radios work. I’m going to avoid the detailed, low-level engineering stuff, apart from saying that designing radios is at least as ...

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) ...
