Edit-Rx-Demodulation-Sweep Screen
Options:
Normal
In this mode the sweep width is controlled automatically by the modem.
The width is always set to +/-32kHz by the modem.
Other
This mode allows the user to set the sweep width in order to compensate
for carrier frequency uncertainty due to Tx frequency, satellite and Rx
frequency conversions. This may be required to optimize performance at
very low data rates by setting a sweep width that is smaller than the
default.
