Legal & safety note
Transmitting can be illegal without a licence and can interfere with safety-critical systems (aircraft, emergency services, medical devices). Only transmit on frequencies and power levels you are legally authorised to use, ideally into a shielded RF enclosure / dummy load or under an amateur-radio licence. This page is educational.
What it does
SimpleWhen your car radio shows the station's name or a song title, that's RDS — hidden text sent along with the music. This app can make that text. It's a neat demo, but only for your own tiny test setup, not real broadcasting.
How to use it, step by step
Simple- Set up a tiny test only (dummy load).
- Open 'RDS TX'.
- Type the station name you want to show.
- See it appear on a nearby FM radio's screen.
