DCF77 Decoder
Software decoder for the DCF77 longwave time signal using raw audio capture rather than dedicated receiver hardware.
Problem
I wanted a direct software path from loop-antenna audio to decoded time data without special-purpose receiver modules.
Approach
The decoder samples audio, detects the amplitude dips in the longwave carrier, reconstructs minute frames, and validates the resulting time payload.
Highlights
- Audio-first decoding path
- Minute-frame reconstruction
- Strong fit for a compiled artifact release later
