Touch Keyer

Amateur Radio Station VE3EFC

My home-brew touch keyer

The paddle is made from cap of a marking pen. I made this keyer by “hooking togther” several different kits: • The CWTouchKeyer P3W circuit card • The N0XAS PicoKeyer • Jackson Harbor sine wave - shaped CPO kit • CanaKit 10 watt audio amplifier • 5V Digikey Reed Relays # 306-1020-ND, with internal diode.
