Iambic Keying, Debunking the Myth by Marshall G. Emm, N1FN. A keying system controls transmitter activation, ranging from basic switches to electronic keyers that generate Morse code based on paddle input. Iambic keyers, introduced in the late 1950s, respond to simultaneous paddle closures with alternating dots and dashes. Despite touted efficiency, actual benefits are modest, offering about a 5% improvement in keystrokes, diminishing at higher speeds. Iambic keying's practical value is limited and may restrict sending speeds.

Article appeared on 73 amateur radio today in 1999 on how to unlock the secrets of sending precise Morse Code. Article contains hints on how use the stright key and the sideswiper key, but even the electronic keyers or the semiautomatic keys.

This circuit stores a morse code message as bits in an EPROM chip, the message controls a relay that keys a CW morse code transmitter. An Arduino processor can also be used in place of this circuit, that eliminates the need to build the circuit and program an EPROM.

Iambic and Straight key amateur ham radio CW Morse code practice oscillators for Android. This Android app gives you both straight and iambic CW Morse code practice key oscillators. Each key translates Morse code into English and CW prosigns in real time as you practice. Practice sending Morse code with a straight key oscillator. Settings include WPM, show/hide Morse code/text, choose sidetone 400Hz-800Hz. Adjust the WPM so that you can produce well formed DITs and DAHs at a comfortable speed.

An introduction to develpment of morse keys in radiotelegraphy history

Microprocessor based interface designed receives a signal from a Morse key, processes it, and re-transmits it to the radio. A microprocessor in the circuit is pre-programmed with a proprietary algorithm which makes a number of measurements and adjustments to the less percise human generated code.

A microprocessor based interface designed to go between a standard Morse code key and a radio transmitter. The circuit receives a signal from the key, processes it, and re-transmits it to the radio.
