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.

An Arduino and a few other choice pieces of circuitry. In particular, [hvde] removed much of the RF portion of the radio, leaving just the parts that dealt with the intermediate frequency at 7.8 MHz.

Because some hardware setup is required to build up a functioning radio, an Arduino can be used to supply the voltage and control the radio chip. The 3.3-V power can be taken from the Arduino’s ...

Arduino enthusiasts looking for a new project to keep them busy over the weekend may be interested in a new Arduino FM Radio Project, which uses an ATmega328-based board to communicate with a ...

Watch the video below to learn more about the new Arduino HamShield directly from its creator who has taken to Kickstarter to raise the required $25,000 needed to take his development board into ...

Short-range radio specilaist LPRS has introduced a stacked module that allows Arduino boards to communicate wirelessly with other Arduino boards or PC hosts. The system uses the supplier’s easyRadio ...
