Differential Operation
If the information for a field is not available, then the field is set to the factory
default.
You can use the following options to specify which part of the beacon
directory you wish to list:
• $PASHQ,BCN,DIR— view the whole directory
• $PASHQ,BCN,DIR,USR— view the user entered stations only
• $PASHQ,BCN,DIR,RTC— view stations from RTCM Type 7 message only
• $PASHQ,BCN,DIR,DEF— view stations from the default list
Saving and Resetting the Beacon Directory
Beacon directory is automatically saved in BBU. The $PASHS,INI,
$PASHS,RST, and $PASHS,SAV commands will not affect beacon directory.
Table 4.7 summarizes the commands for saving, editing, and deleting the
beacon directory.
Working with Never Used Frequencies
In Automatic Modes, you can mark a frequency to “never be used” using the
$PASHS,BCN,NVR, f1 command where f1 is the frequency.
All stations with the specified frequency will not be searched for after issuing
this command.
