About Us

VIBROPLEX is the oldest continuously operating business in

Amateur Radio, founded in New York by Horace Martin, inventor of the

semi-automatic Morse Code key in 1905.

Today, 109 years later, VIBROPLEX is located in Knoxville, TN, USA and continues to manufacture the original Martin key ("Original bug") as well as a complete line of some 30 keys including bugs, iambic paddles, single-lever paddles and traditional straight keys.  These keys are manufactured in the United States of America in our offices in Knoxville.

Let us introduce you to our other product lines:  SPIDERBEAM is a German company manufacturing high-quality portable and heavy-duty wire yagi antennas, collapsible fiberglass poles and aluminum masts in heights from 33 to 85 feet, and various wire antennas and accessories.  VIBROPLEX is the exclusive distributor for USA and Canada for SPIDERBEAM products.
