4. Go down one line, and edit the satellite
channel frequency
1 .
This sets up the tuning frequency in the receiver.
5. Go down to the next line, and enter the
Symbol rate. This sets up the incoming symbol rate of the
demodulator.
6. Continue on line down to the Inner
Code rate, select the correct inner
code. This sets up the Forward error correction (FEC) rate of
the demodulator.
7. For the final three items, select the
correct LNC voltage, and turn 22 kHz
control signal and spectrum inversion
on or off. This finalises the set-up of the satellite demodulator.
Right to SET:DEMOD, status information about the
signal lock is being displayed. (Signal strength.)
