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 ...

There was a time when only the richest ham radio operators could have a radio with a panadapter. Back in the day, this was ...

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 ...

Many of today’s experienced engineers got their start in electronics through amateur, or “ham,” radio. (Many theories exist over the origin of the term “ham radio,” but there is no consensus.) Over ...

We should be able to build a complete, simple direct conversion receiver on a chip using current IC technology. The possible receive frequency would be limited by the IC technology used for the mixers ...

Software-defined radio (SDR) is a flexible and high performance signal processing and radio communication system that employs certain software-based modules instead of traditional hardware-based ...

Electronics enthusiasts, makers and hobbyists might be interested in a new Kickstarter campaign which has been launched by Hobby PCB for its RS-HFIQ 5W Software Defined Radio (SDR) Tranceiver. Watch ...

While most hams of his generation struggle to come to grips with the constantly evolving software-defined ham radio system, Madhavan is on top of it. As a qualified engineer, Madhavan has a clear ...
