What OnAir shows
ISDB-S, Japanese BS satellite television (12 GHz through an LNB): 28.86 Msym/s, BPSK / QPSK / TC8PSK slots, TMCC, Reed-Solomon; needs a radio that samples 39 Msps or more.
Limits and what it was checked with
Checked with generated signals and impairments; recordings of real signals welcome.
Which radio you need
This mode sits at a high frequency, so check that your radio tunes it: a HackRF covers 1 MHz to 6 GHz, and RTL-SDR stops near 1.7 GHz. Some modes at these frequencies also need a fast radio (10 to 20 Msps) or a dish and an LNB.
Receiving and the law
Questions about ISDB-S (BS)
Can I decode ISDB-S (BS) with an RTL-SDR?
No: wide TV channels need a radio that samples faster than an RTL-SDR, which reaches about 2.4 Msps. See the radio guide.
Is it legal to receive ISDB-S (BS)?
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 ISDB-S (BS) 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.
