The QN8066 is a fun little FM transmitter chip. It covers the full FM broadcast band and has built-in DSP. You would find this sort of part in car cell …read more Continue reading Be your own DJ with QN8066 and an Arduino Library
For a long time, a Morse code proficiency was required to obtain an amateur radio license in many jurisdictions around the world, which was a much higher bar of entry …read more Continue reading CW Not Hard Enough? Try This Tiny Paddle
It’s said that “Golf is a good walk spoiled,” so is attaching an amateur radio to a bike a formula for spoiling a nice ride? Not according to [Wesley Pidhaychuk …read more Continue reading Going Ham Mobile on a Bicycle
Begun, the Spectrum Wars have. First, it was AM radio getting the shaft (last item) and being yanked out of cars for the supposed impossibility of peaceful coexistence with rolling …read more Continue reading Hackaday Links: July 7, 2024
Have you ever thought about getting into digital modes on the ham bands? As it turns out, you can get involved using the affordable and popular Quansheng UV-K6 — if …read more Continue reading Hacking a Quansheng Handheld To Transmit Digital Modes
In the days before integrated circuits became ubiquitous, providing advanced functionality in a single package, designers became adept at extracting the maximum use from discrete components. They’d use clever circuits …read more Continue reading So Much Going On In So Few Components: Dissecting A Microwave Radar Module
Morse code, often referred to as continuous wave (CW) in radio circles, has been gradually falling out of use for a long time now. At least in the United States, …read more Continue reading Learning Morse Code with a DIY Trainer
We’ve been harping a lot lately about the effort by carmakers to kill off AM radio, ostensibly because making EVs that don’t emit enough electromagnetic interference to swamp broadcast signals …read more Continue reading Hackaday Links: June 9, 2024
The universe is awash with strange radio signals, but astronomers have now detected a really bizarre one that repeats every hour, cycling through three different states. While they have some ideas about its origin it can’t be explained by our current u… Continue reading Radio signal from space repeats every hour, defying explanation
[Stephen McNamera] found a schematic for a grid leak radio online and decided to throw together a few tubes on a piece of wood and see how it worked. As …read more Continue reading Grid Leak Radio Draws the Waves
