CW DECODER ARDUINO HOW TO

The original programmer is Hjalmar, OZ1JHM, he will be way more qualify to answers these questions, but it is my understanding that the sampling freq is derived from the analogRead() function which takes 100 microseconds leading to a theoretical sampling rate of 9600 Hz. So as you may know, I am not the original programmer of this code, I ported it to work on an arduino NANO.

If you have any questions or comments, feel free to leave your message below. If you want to download the fabrication files click here and scroll down to the Export Data Design section. My version allows you to select the target frequency and also the bandwidth via jumpers.Д¬ompleted PCB.

You can etch, CNC machine or send out the files for fabrication. In addition I also designed a single sided PCB version of the board for those who want to give it a try. I have deiced to post the schematics of my implementation and also the code I use on my version of this project.

CW DECODER ARDUINO HOW TO

Most of the questions I get are about how to connect the components. I receive a lot of questions on this project. This post was made 1 year ago exactly to the date but it is the most viewed article on this site. If you are interested on building this CW decoder, but need assistance or have any questions feel free to send an email to. To increase the flexibility a microphone like this can be added to the circuitry. The вЂњsketchвЂќ programmed in to the Arduino is based on the GoertzelВ Algorithm for those who are interested on how it works. Hjalmar published the schematics and source code for everyone to use. This Arduino based CW decoder was developedВ by Hjalmar, OZ1JHM.
