Today marked a milestone in my investigation into using Claude Code with a complex codebase. I had a FreeDV RADE contact with another station using code it wrote under my instruction in just one week - very much part time. Here's a receive demo:
My thanks as always to Joe, VK3SRC, for assistance in testing and feedback. Also thanks to Britt, VK3AOB who responded to my first call which I really expected to not be decodable.
Here's how Claude Code looks while working on a bug in the code (click to enlarge):
I'm developing on Linux Mint. The app is C++ using GTK and Claude seems very knowledgable in this scenario. I suspect that the large amount of open source software around is a great advantage for this sort of thing.
The code is here: https://github.com/peterbmarks/radae_decoder As you can see the name of the project is no longer correct as it encodes as well.
I heard something about asymmetric voice peaks on the video clip. Couldn't some kind of voice symmetricizer filtering be added to FreeDV ? This is fairly easy to do in hardware per W3AM:

Anyway, it sounds pretty good to me !

Yes Chuck. As that article says, it's common with AM broadcast stations to flip the phase of the audio so that peaks go up rather than clipping at zero.
