A Home Made Paddle Key & Keyer.
This home made twin paddle morse code key was designed by Steve Taylor / G4EDG. Overall length is about 5.5" (140mm) and made out of bits of copper sided board and odds and ends. The keyer circuit ( a "PK-3") was bought as a kit from Jackson Harbor Press in the USA and has a pot for speed control plus loads of memory functions. Great fun along with my QRP rig.
