fm-rds-tx

CPU-first FM stereo transmitter with RDS, written in Go.

Goal

Build a software transmitter pipeline for a licensed short-term VHF/FM broadcast project:

• FM mono/stereo multiplex generation
• RDS encoder/inserter
• configurable audio and RDS inputs
• configurable carrier frequency, deviation / MPX levels, and TX chain settings
• CPU implementation first
• optional CUDA acceleration where it actually helps
• target platforms: Windows first during initial bring-up, then broad cross-platform support including Linux and Raspberry Pi / SBC targets

Important note

This repository is intended for lawful use only within Jan's licensed project window and under applicable radio regulations. Hardware output stages, spectral compliance, filtering, and actual radiated power must be validated against the license conditions and local law.
