Vibroplex® - The Oldest Name in Amateur Radio.

Vibroplex® is the oldest continuously operating business in Amateur Radio, in our 113th year.  We were founded in New York in 1905 by Horace Martin, the inventor of the semi-automatic or "bug" morse code key.  After many years in New York and a handful of ownership changes over the 113 year period, Vibroplex has been operating in Knoxville, TN since 2009.  Vibroplex® presently manufactures morse code keys under the Vibroplex® and Bencher® brands.  Our keys are manufactured in the USA with USA sourced parts. 

Vibroplex® is also the owner of International Radio ("INRAD"), a manufacturer of aftermarket crystal filters and roofing filters usable for transceivers and receivers from the 1960's to the present day.  We are also the supplier of OEM filters for the Elecraft K3S transceiver.  The 2017 introduction of the INRAD line of microphone and headset products is the first of many new offerings coming in the future from this long standing brand name. 

With W7FG Vintage Manuals, Vibroplex® creates and ships high quality reproduction manuals for vintage Amateur Radio, shortwave radio, scanners, audio and test equipment.  We have 17,000 titles in stock for service and operation manuals for equipment from the 1930's to the present day.

In addition to our own products, Vibroplex® is the North American distributor for Spiderbeam, Easy-Rotor-Control, 4O3A Signature Products, DX Covers, and DXPatrol receivers.
