GMorse - A complete Morse code decoder from scratch
This project idea was born when I got my amateur radio license in 2024 and started poking around radio stuff. What I find particularily interesting are the digital modes (computers talking over the radio) and continuous wave (CW). CW is mainly used to communicate using Morse code across the globe.
Although it is an obsolete technology, a lot of amateur radio operators learn it and continue to use and make contacts using Morse code. Yup, that’s right, if you hang up an antenna, get some radio equipment, and listen, you can still hear morse code being sent in 2025.
This piqued my curiosity and as I was starting to learn morse code, I thought that it would be pretty cool to have a learning aid that decodes Morse code as it is received by your radio. Now, some radios have this built in (mine doesn’t) and you can find them for pretty cheap on Amazon, I was wondering how to put a software decoder together and decode morse by hooking up a computer to the radio. This project was put together specifically to answer that question so come on down the rabbit hole and let’s put one together from scratch.
