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 makes a plain, steady radio 'note' at one frequency. Engineers use it to test whether a radio or antenna is working — like humming a single note to check a microphone. Only use frequencies you're allowed to.
How to use it, step by step
Simple- Pick an allowed frequency.
- Open 'Signal Generator' and set the frequency.
- Turn it on and check it on another radio.
Examples
Antenna check
Emit a carrier and measure it on Level to compare two antennas.
