Simple Circuit electronic keyer
Serious CW operators know that a paddle is the way to go to make CW easy and fun. But along with the paddle, a certain amount of electronics is needed to produce the necessary dots and dashes. This circuit in figures 1a and 1b is a simple keyer which can be built for as little as $6 with some junk box parts. Although this circuit is not a true iambic keyer, it is capable of producing perfectly sounding CW. To make construction easy, all parts are available off the shelf at any Radio Shack store. __ Designed by N1HFX
Simple Circuit Morse Practice Oscillator
This will be my next Homebrew project, a morse practice oscillator circuit.9W2AZV and I are going to build this as we are preparing ourselves to perfect our Morse code sending/receiving skills. In the spirit of amateur radio/ham, we will homewbrew. __
Smooth Tone Clickless CW SideTone Generator
This circuit is about as good as it gets for generating morse code tones. It may be used as a code practice oscillator, a tone generator for a keyer, a sidetone oscillator for a CW transmitter or an audio Modulated CW (MCW) generator for an FM transmitter or repeater __ Designed by G. Forrest Cook

Two key projects
This is a circuit that I particularly like due to its simplicity and speed of construction. With this circuit, it is now possible to include a paddle keyer as an integral part of all, but the smallest, of QRP CW transmitters. It also satisfies my hate for CMOS

Two Way Morse Practice Set
The first step to learning Morse is to be able to memorise the sounds of all letters and numbers. This can be accomplished with the help of Morse practice tapes or classes. Once you know all the characters, the WIA Morse practice broadcasts and/or continuous VHF Morse beacons can be used to increase your receiving speed. __ Designed by Peter Parker VK3YE-first appeared in Amateur Radio, April 1998
