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.

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...

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!"

This QCX-tranceiver holds also a “mini-straight key” on the PCB, a full Iambic keyer circuit and a digital CW decoder. On the PCB are 2 small IC’s in SMD form, but already mounted at the factory.

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. The magic in this code is the tone detection based on the goertzel formular, which means that you just put in the audio on an analog pin and then the processor make some calculations and if there is a ...

Arduino CW Decoder. This program is a modified version of "OZ1JHM CW Decoder VER 1.01", originally developed by Hjalmar Skovholm Hansen OZ1JHM. These modifications were made by [email protected] on Sep. 15th 2024. Videos: With Grove - I2C 16x2 RGB Backlight LCD: https://www.youtube.com/watch?v=-MJKqybjeTU

Jul 30, 2015 · As mentioned Budd Churchward had created a series of videos on how he wrote the Sketch, created a PCB and published his code. ( Budd’s Sketch is available here ) I simply downloaded the sketch and uploaded it to the Arduino.

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.

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.

When you hear a cw station, turn the vfo until the led starts flashing green. If you are too high or too low, the color is red or blue. This decoder works best for me.
