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 ...

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 ...

Software-defined radio (SDR) is a very powerful concept. Its technologies provide software implementation of modulation, interference management, and capacity enhancement techniques over a broad ...

Evaluating tactical software-defined radios (SDRs) poses no small challenges for test engineers. Even when considering only the analog hardware attributes of these radios, a test engineer is faced ...

A software-defined radio (SDR) uses a general-purpose computer processor to perform aspects of digital signal processing in place of analog circuit hardware. This allows for greater flexibility in ...

Transform your Raspberry Pi into a powerful tool for radio communication, capable of exploring frequencies that stretch up to an impressive 6 GHz. The CaribouLite Raspberry Pi radio HAT makes this ...
