CubeSats are tiny satellites which tag along as secondary payloads during launches. They have to weigh in at under 1.33 kg, and are often built at low cost. There’s even open source designs for these ...

The University of Kent’s hackerspace, TinkerSoc, recently had a talk on software-defined radio using an incredibly inexpensive USB TV tuner. Of course this is nothing new to Hackaday readers, but they ...

A radio receiver consisting of just a very good analog-to-digital converter connected directly to the antenna plus a powerful computer could make a great radio. However, the present state of the ...

The operation of ground stations and phased-array antennas. How SDRs are integrated into ground stations. Issues to be considered when incorporating SDRs into phased-array antennas. Examples of ...

Every passing year sees radio transceivers get nearer to the ideal software-defined radio (SDR). The "ideal" will occur when the antenna is connected directly to a DSP baseband processor, which ...

Software defined radio (SDR) has been one of your popular search topics this year on RF DesignLine. Recently I had the opportunity to hear from some people who are very active in this market: Frank ...

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 ...

The release of a standard defining interfaces and APIs for a unified architecture among smart antenna vendors was announced by the Object Management Group (OMG) and The SDR Forum today. The “PIM and ...

How does the new HackRF Pro perform in practical tests? We compare it with its predecessor, the HackRF One, and analyze improvements in RF characteristics.

Hobbyists who listen for distant signals often face a dilemma. The best places to hear distant “DX” signals are in remote and rural areas that are free of electrical interference. Unfortunately, many ...
