might be necessary to input an IF frequency that will help you peak on the
Target Satellite without the signals from the adjacent satellites causing the
Dish to pull off and peak onto an adjacent satellite. In this situation a
value other than 0 can be used. See Building a Sat Table for additional
information.
Modem Symbol Rate
Hughes critical setting! The Bandwidth Provider (VAR) will supply the
Symbol Rate required for the modem to lock to the correct RF carrier
The symbol rate is entered in Msps (Mega Symbols per Second).
Example; 30,000,000 symbols per second is entered as 30 Msps.
Search Frequency
The Search Frequency is the initial frequency set in the J1 Controller
Tuner to find most Satellite Signals in the sky.
Depending on the general center frequencies of most of the Satellites in
the viewable orbit above your GPS Longitudal position this value can be
changed.
In North America most Ku Band Satellites have a many transponders that
are near 1250 MHz IF. So using 1250 MHz is recommended.
Check Satellite Charts for the particular region in the world you plan to
operate and make changes as needed.
Search LNB
The J1 Controller has the ability to search using one LNB and then switch
to a second LNB for proper Modem operation. Under normal conditions
the Modem LNB, Search LNB, and Target LNB will be set to LNB A.
If the Satellite you are wanting to find is not in the same RF Frequency
band as most of the Satellites in the satellite arc (belt) above, then using
one LNB to search and then switching to another LNB for the Modem to
lock is possible with this setting. A Dual Band LNB is required for this
configuration.
See LNB Settings Page for additional information for LNB setup and use.
