Base Frequency
Base frequency is an ASTRO transmission parameter. This setting should
normally be set to 10.982 GHz unless otherwise advised by ASTRO.
Code Rate
Code rate is an ASTRO transmission parameter. This setting should
normally be set to 7/8 unless otherwise advised by ASTRO.
Symbol Rate
Symbol rate is an ASTRO transmission parameter. This setting should
normally be set to 30.0 Mbauds unless otherwise advised by ASTRO.
Modulation Channel
Modulation channel is the RF output channel of your DMT. You can select
your DMT's RF output channel in the UHF band ranging from channel 21 to
69. Note that if you decide to change this setting, your television will need
to be re-tuned in order to receive the ASTRO RF signal on the newly
selected UHF channel. If you are experiencing interference from other local
TV transmission while using the UHF antenna input on your TV to revive
ASTRO, you may need to experiment with this setting.
Note : If you are using an A/V connection into the Audio and Video inputs of
your TV or Home Theater system then this RF frequency setting has
no effect.
