The Michigan Mighty Mite is a very simple crystal controlled CW transmitter that uses very few parts, is easy to build, and a fun little ham radio project. Simplicity comes at a price, and that price is harmonic distortion. A low pass filter is shown that helps to dramatically reduce the distortion. This Mite is built with a 3.579MHz "color burst" crystal. Inspiration for building the Mighty Mite came from the Soldersmoke blog and podcast.
