Simple 80m CW transmitter & Low Pass Filter

[VK4GHZ]

From W2AEW

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

This is interesting, especially the bit about building the LPF and the available software programs. Thank you for posting it.

I wonder if it could be modified to work on 600m?
