Is your ham radio rig made of iron and steel? Is it mechanically driven? Classified as a World Heritage Site? We didn’t think so. But if you’d like to tune in one that is, or if you’re just a ham ...

For the first time in history, a prototype radio has been created that is claimed to be completely digital, generating high-frequency radio waves purely through the use of integrated circuits and a ...

Cambridge Consultants are claiming the world’s first fully digital radio transmitter built only from computing power. There are no analog components like a high-speed D to A converter with amplifier, ...

Amateur radio is the only hobby that offers its licensed operators the chance to legally design, build, and operate high power radio transceivers connected to unlimited antenna arrays for the purpose ...

For the first time, researchers have used a laser as a radio transmitter and receiver, paving the way for towards ultra-high-speed Wi-Fi and new types of hybrid electronic-photonic devices. You've ...

Engineers have developed a fully implantable radio-frequency transmitter chip for wireless sensor nodes and biomedical devices. Purdue University innovators are working on inventions to use micro-chip ...
