  • Channels

We will now scan for SD and HD channels separately. First we will scan for the DVB-S (SD) channels. To do this, enter the details for one transport and it will find the rest. Hit "Scan for channels" and enter the following details:

Freq: 10714000
Polarity: Horizontal
Symbol rate: 22000000
Mod Sys: DVB-S
FEC: 5/6
Modulation: QPSK
Inversion: leave at auto
Rolloff: leave at 0.35

The channel scan will take a few minutes to complete. Check the /var/log/kern.log file if you have problems. Now we will scan for the DVB-S2 (HD) channels using the following details:

Freq: 10847000
Polarity: Vertical
Symbol rate: 23000000
Mod Sys: DVB-S2
FEC: 8/9
Modulation: QPSK

Rolloff: leave at 0.35

Hopefully it will find BBC HD, BBC ONE HD, etc.
