and buying the add-on would cost more than the radio did. 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 ...

There was a time when a ham radio set up sported many dials and switches and probably quite a few boxes as well. Computers have changed all that. Some transceivers now have just a few buttons or ...

The humble ATmega328 microcontroller, usually packaged as an Arduino Uno, is the gateway ... He has managed to implement a software-defined SSB ham radio transceiver for the HF bands on the ...

Hooking these up to the Arduino gave him a programmable way to control the device. He got his radio license and implemented transmission of Morse Code, and an Arduino sketch is available in the ...

That’s good enough for AM radio, anyway, but you’ll need to try this DIY FM receiver if you want to listen to something more culturally ... is controlled by an Arduino including a small ...

Video killed the radio ... ham wanted a beam antenna or a cubical quad or some other type of rotating directional antenna. Being able to swing an antenna at a particular direction brings more ...

[William Franzin] decided it would be particularly cool to make the service available over ham radio – and that’s exactly what he did. [William] got the idea for this project after first ...

As many a radio amateur will tell you, ham radio is a hobby with as many facets as there are radio amateurs. It should be an exciting and dynamic place to be, but as those who venture forth into ...

Most radio circuits are tuned to pretty close tolerances and going from 27 MHz to 50 MHz seemed like quite a leap. The answer? An Arduino and ... If you want to learn more about the digital ...

Even though manufacturers of handheld ham radios have been busy adding all ... for programming or otherwise communicating between the radio and a computer, very few can use USB for power.

[Mike] remembers and built one, presumably more to discuss the safety precautions ... Built on an open board and with no ground wire, the radio didn’t need a complex power supply.
