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
SimpleThis turns the device into a tiny radio station using the built-in microphone. Whatever the mic hears can be sent out on a radio wave. Because you could accidentally cover a real station, you must only do this on channels you're allowed to use.
How to use it, step by step
Simple- Only pick a channel you're allowed to use.
- Open the 'Audio TX' app.
- Talk into the microphone.
- Listen on another radio to hear yourself.
Examples
Receiver bench test
Transmit a test tone into a dummy load to confirm your other receiver decodes it.
