What do you pick when you want to make something with a nostalgic touch? A radio, of course! Well, the project presented here is about building a compact Arduino FM Radio with the help of an ...

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 a few other choice pieces of circuitry.

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.
