So [Todd] has set out to build an Arduino frequency counter for a Kenwood TS-520S HF ham radio. This post (and the video found after the break) doesn’t cover the entire project. It’s rather ...

But there were other looks for test gear back in the day, as this frequency counter with a readout using moving-coil meters shows. We have to admit to never seeing anything like [Charles Ouweland ...

The program is set to collect data and evaluate EnforceAir C-UAS system's capabilities in airport environments. D-Fend ...

RF frequency converters are integrated component assemblies required for converting microwave signals into lower (or intermediate) or higher frequency ranges for further processing. They generally ...
