A CW encoder written for the ARRL and presented during Hamvention 2024. BOM and Circuit Diagrams Available in the ReadMe file. Please feel free to use this as you like.

Oct 17, 2023 · With an Arduino, an LCD module and a few components you can have your own pocket-sized "secret decoder" that will do up to 80 wpm, enabling even you the "noob" to dive feet first into the CW bands with an electronic set of "swimmies!"

Jan 7, 2023 · (1) Open your arduino IDE, copy and paste the arduino code below, make sure it compiles. That’s it! If you follow my notes and use identical hardware, you should now have a working cw decoder.

Jun 13, 2024 · This device is especially useful for HAM radio beginners, and also SW listeners who can monitor CW communications without knowing Morse code.

This program reads text characters typed from the Arduino IDE monitor's keyboard and generates Morse Code for sending to a transceiver. It can also read text from a series of precoded buffers stored in the software.

easy build cw decoder based on dsp goertzel code If you want to build a cw decoder without using other active components than an atmel 328 - Arduino UNO , then this is sure something for you.

If the signal is weak, noisy or keyed with a paper clip, even the best decoder, namely your ear, could have difficulty perceiving a message. Do you want to play with CW (telegraphy) decoder, so this is a very nice little project that will not cause you much anguish. My version of the program can be DOWNLOADED here...

Apr 22, 2023 · This is an open source Arduino based CW (Morse Code) keyer with a lot of features and flexibility, rivaling commercial keyers which often cost significantly more. The code can be used with a full blown Arduino board or an AVR microcontroller chip can be programmed and used directly in a circuit.

Morseduino, Semi-automatic CW decoder. This project exists of a Semi-automatic CW Decoder, Called Morseduino. This decoder detects automatically the right tone and speed of the received CW signal. There is also a programmable noise-filter. In about 80% of the time, the tuning and decoding of the signals is very good.

Mar 31, 2014 · I recently started playing with Aruduino boards for various ham applications, and thought a CW program for the Arduino might be fun. This article describes hardware and firmware for encoding and decoding of on-air CW using an modem based on these controller boards.
