Secondly, it’s ideal to use 1K ohm resistors than 100-ohm base resistors.

First, every capacitor value is in uF (Microfarads) unless the requirements differ.

Here are a few things you should note from the schematics

CW speed is adjustable from 1-to-999 WPM.

Up to six selectable transmitter keying lines, and.

Programming and interfacing via USB port,.

An optional speed potentiometer (commands can also adjust speed),.

Hellschreiber mode (beacon, memory macro, keyboard sending),.

Various practice modes and training modules,.

Finally, it has a low output/sidetone high/sidetone disable functioning to the key outboard audio oscillator.

Then, it also has optional PTT outputs with configurable hang times, tail, and head.

Again, it has an optional LCD (classic I2C displays and 4-bit LCDs supported).

Further, you can operate k3ng with a CW keyboard without using a computer since it has a PS2/USB keyboard interface.

It has a logging and contest program interfacing through 2.0 interface protocol emulation and K1EL Winkey 1.0.

Additionally, it has a command mode that enables the paddle to program memories, change settings, etc.

Its modular code design allows you to select features and have an easy code modification.

It also has non-English character support.

Thirdly, there’s a rotary encoder speed control, and CW receives the decoder.

Then, it has an alphabet sending practice, USB mouse support, and a sleep mode feature.

First, its web interface exists but is under development, and it has a ‘Messy’/QLF straight key emulation.

The main features of the k3ng Keyer are as follows Moreover, since it’s an open-source code, it is easily customizable as per one’s requirement. Often, it’s ideal when permanently installing it inside a rig, e.g., a homebrew QRP rig or as a standalone keyer. Furthermore, you can use it with an AVR MCU chip/full-blown Arduino board, whereby you’ll program and use it directly in circuits. K3ng is a relatively cheaper open-source keyer that’s Arduino-based Morse Code/CW with excellent flexibility and several features.

We’ll show you its features, schematic, and a project you can accomplish while using the device. In today’s article, we’ll elaborate on a type of keyer known as the k3ng keyer. For example, we have a keyer in a telegraph key form that functions in keying Morse codes. A keyer is a piece of equipment allowing signaling by hand via pressing single or more switches.
