Took the TETRA signal analysis further:
Extracted the TDMA frame structure from the power envelope using a simple FFT-of-FFT approach. TETRA frame period confirmed at 55 ms (spec: 56.667 ms).
Two standalone scripts, pipe them together: extract_power_envelope.py | find_periodicity.py
I been working on a project. This is focused on vhf propagation at your antenna. I made the decision to provide it free, with a donate button in the about section.
If that interest you see more shoot it here https://t.co/UVoy7TtuDE
