Challenge
I’m going to try to write my own FT8 decoder with:
- An LLM tool in strict socratic mode where it will not write code or solve problems, but only ask questions.
- Posts of status at 7:00 AM on Monday and Friday.
My solution will be independent from the canonical FT8 decoder in WSJT-X.
There’s at least one public python solution. I’ve seen it. I won’t look at it again during the challenge.
Note
If I find any other solutions, I’ll avert my eyes immediately.

What does success look like?
At the outset, I’ll make a 20-minute reference recording of audio on the main JT8 frequency, 14.074 MHz, and decode that with WSJT-X.
To assess my solution, I’ll decode the same audio myself and compare the results.
