SEMI-AUTOMATIC "BUG" keys
Horace Martin, founder of VIBROPLEX, invented the semi-automatic "bug" key and started the VIBROPLEX company in 1905. He got it right on the first try: 111 years later, we are still offering Martin's original key design for the active Amateur Radio operator. The "bug" key represents a hand back to the rich tradition of CW operation in the hobby and many of them are in use on the air today with each operator's distinctive fist giving their code transmission a unique sound on the air. An item you can buy today, and treasure for many years to come! Bug keys are designed for 20-50 WPM operation, but can be slowed further with the addition of the Vari-Speed device shown below.
