Electronic Keyers & Keyer Paddles

With the invention of the vacuum tube, and later the transistor, it naturally followed that clever designers would invent electronic devices to simplify the generation of Morse Code so that CW operators could send code with even less wrist motion than required to operate a bug. Hence, the electronic keyer was born.

The first commercial electronic vacuum tube keyer was the Mon-Key, sold by the Electric Eye Company of Danville, Illinois starting around 1948. The Mon-Key, like all electronic keyers, automatically produced Morse dots when the keying lever was moved to the right, and Morse dashes when the lever was moved to the left. As with all the early keyer designs, the keying lever was integrated into the keyer unit, often with the paddles protruding from the front of the cabinet. Two knobs controlled the speed of the Morse code and the volume.

Most of these early keyers were kind of clunky to operate because they didn't have the best quality keying levers, but this was not something the operator could control. In addition, the Mon-Key was actually sort of a dangerous instrument to operate, as 120V AC was present on the metal keying lever itself, so if you removed the plastic cover from the keying lever assembly, you could get a nasty shock if you accidentally touched the lever !

Towards the end of the 1950's, people were starting to design the mechanical keying mechanism and the electronic keyer separately. One of the most popular stand-alone keyers was designed by W9TO (The TO Keyer), and was mass-produced by Hallicrafters Radio Co. The mechanical mechanism became known as a Keyer Paddle. This separation allowed for the development of many interesting keyer paddle designs, which continue to this day. Some of the first keyer paddles included the El Key, the Nikey, and the famous W8FYO paddle.

There were 2 types of keyer designs, Non-Iambic and Iambic. A Non-Iambic keyer uses a paddle with a single lever, which is moved to the right or left, depending on whether the operator wants to make dots or dashes. All of the early electronic keyer designs used Non-Iambic operation.

An Iambic keyer uses a paddle with 2 levers, the right one controls dashes and the left controls dots. What gives the Iambic keyer its name is that if you squeeze the left and right paddles together, the keyer produces an alternating string of dots and dashes, which gives the Iambic keyer a huge advantage when sending Morse characters such as "C", "K", or "R". Thus, Iambic keyers are the easiest to operate since they require the smallest amount of hand movements.

The first Iambic keyer paddle to appear on the market was The Nikey, designed by Nicholas Lefor, W2BIQ. The Nikey was first advertised in 1962 and made by Lefor Industries of New Canaan, Connecticut.

With the invention of transistors and microprocessors, the next step in keyer design was the memory keyer. Many keyers made today have the ability to store short Morse code messages which can be re-played at the touch of a button. This is a great thing for amateur radio contest operators, who can use this feature to automatically send out repetitive messages such as callsigns and the other short exchanges of information that are sent during contests.

Today, there are some really nice keyer paddles being made by master craftsmen such as Pietro Begali, Alberto Frattini, Mike March, and others. You can see examples of their amazing work in the photos below. Many of these paddles are available for purchase, but be forewarned.....quality comes at a price !
