Off-grid Communication Terminal (Fallout-inspired)
This DIY project is designed to enable secure and resilient text communication over analog radios using AFSK modulation (1200 baud), GPS-based time synchronization, and AES-256 encryption.
All components are integrated into a compact, off-grid terminal that looks straight out of Fallout.
