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 ...

While most smartphones can receive at least some radio, transmitting radio signals is an entirely different matter. But, if you have an Android phone and a few antennas (and a ham radio license) it ...

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 ...

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 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 ...

THE RADIO. It’s been around for more than 100 years. Pioneering work by Guglielmo Marconi and others in the1890s and 1900s resulted in practical wireless telegraphy devices that permitted ...

We’ve all used walkie-talkies at one point or another, or seen a cop do it on some movie. Short-hand radio has been around forever, but creating your own radio to listen in can cost hundreds of ...

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 ...

SDR (software-defined radio) promises operators massive cost reductions. Cognitive radio will soon furnish bandwidth on demand. SDR forces re-evaluation of superhet and direct-conversion technologies.
