Tips and caveats

• Used and checked on real broadcasts.
• Which radio: No: wide TV channels need a radio that samples faster than an RTL-SDR, which reaches about 2.4 Msps. See Supported radios.
• Try it without a radio: most modes include a built-in synthetic test signal, so you can open the screen and try the controls first.
• Receiving and the law: Receiving free-to-air broadcasts is legal in most countries. OnAir cannot decode encrypted or scrambled services, and does not try to. See Legal.
