August 11, 2023: Pulser kit

The Pulser kit is a simple circuit which converts a square wave input (such as the markers from a VE3DNL kit) to a once per cycle brief pulse or spike. This pulse results in harmonics which are more even in amplitude than a square wave. More on this circuit can be found in my old markers.pdf file.
