Hi,There is my DIY project that detects nearby TETRA radio activity using a Raspberry Pi 3 and an SDR dongle.

https://github.com/IDEall/bluebark-lite

Written mainly in Python, with some Cython parts for better performance.

Current setup:

• Raspberry Pi 3
• DietPI ARM64
• Nooelec V5
• Python + Cython
• Basic UI / notification logic
• Designed to run on low-power hardware

I’m sharing it in case someone wants to learn from it, test it, improve, or build something similar.
