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
