A Scarce Piece of Vibroplex History! (view current auction to bid)

Here’s an interesting one from our curent auction — a Vibroplex “Know Code” Limited Edition Straight Key, Serial No. KC-212.

Vibroplex introduced the distinctive red “Know Code” key in 2007, shortly after the FCC eliminated the Morse code examination requirement for amateur radio licenses. It was a clever response to the new “no-code” era — you may no longer have to know code, but Vibroplex still thought you should KNOW CODE!

Each was individually numbered with a KC-series serial number, and this example is KC-212. It also has the earlier engraved/embossed brass identification plate; later examples reportedly used a silk-screened aluminum plate.

With its bright red base, matching Navy-style k**b, chrome mechanism and special KNOW CODE nameplate, these limited-edition keys don't turn up very often. A neat piece of relatively recent Vibroplex and amateur-radio history — and a great addition to a serious CW or telegraph-key collection.
