PL Tone Encoder Board If your local repeater has got you singing the PL tone blues, then read on.  For less than $10, an inexpensive PL tone generator can be constructed that will bring new life into that old non-PL rig. __ Designed by Radio Amateur Society of Norwich

QRP Keyer This is not a sophisticated automatic keyer but it is lot QRP to build and to have fun operating it.   When the paddle is connected to the DOT terminal, C1 starts to charge.  When C1's charge reaches sufficiently high value, it causes the transistor BC157B to conduct and pulls the relay and key the transmitter. __ Designed by K P S Kang

RF Actuated CW Monitor amateur radio construction projects. __ Designed by Peter Parker

Simple  Morse Code Trainer Morse code contests are still held in some parts of the world.  Practising the Morse code with a simple Morse key kit is interesting.  The circuit given here can be used to...___ Electronics Projects for You

Simple Circuit CW Keyer based on Atmel ATtiny 2313 This is a simple and small CW keyer project.  It uses an ATMEL ATtiny 2313 (Atmel's ATtiny2313 page) microcontroller, which is a 20pin device with 2k flash memory.  The firmware is written in C and uses less than 1k.  The pin count would allow for the use of a 8 pin device but the 2313 was simply the part at hand __ Designed by © 2007 Michael Wichmann

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

Talking Morse Code Practice Computer Schematic Only __ Designed by Ken Staton

Touch CPO touch operated code practice oscillator using popular timer IC555.  Practice Morse code in a different way __

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 !! __ Designed by Harry Lythall-SM0VPO

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
