5. Modem protection from interference
If interference contains a big power at some frequency such frequency (“unwanted frequency”) can be
excluded from the use. To eliminate unwanted frequencies they should be placed to list and saved in
configuration file.
5.1. NLST
The NLST command prints the list of
“unwanted frequencies”
. By default the list is empty.
5.2. NADD
The NADD command adds some frequency to the list of
“unwanted frequencies”.
The added value of the
frequency is rounded to the nearest used for frequency hopping.
