Questions about DVB
Can I decode DVB with an RTL-SDR?
Usually yes for narrowband signals, as an RTL-SDR tunes roughly 24 MHz to 1.7 GHz at up to about 2.4 Msps. Wide signals such as TV channels need a faster radio, and OnAir says next to the source what the selected radio can do.
Is it legal to receive DVB?
Receiving free-to-air broadcasts is legal in most countries. OnAir cannot decode encrypted or scrambled services, and does not try to.
Can I try DVB in OnAir without a radio?
Yes. Most modes include a built-in synthetic test signal, so you can open the screen and try the controls before you own a radio.
