THE TOUCH PADDLE / KEYER
The Touch Paddle is from QST  July 2004 W8NUE.
It has been combined with a Keyer and a Piezo buzzer
(sidetone) to form a complete morse sending system.
The keyer / paddle interfaces with the Tornado nicely.
The keyer is from N1HFX : http://www.rason.org/Projects/cwkeyer/cwkeyer.htm
