LinBPQ was installed during the build.
You will find the config file generator
under accessories in the main pi menu.
NO CONFIGURATION was done for LinBPQ
during the build. Each individual
operator is responsible for configuring
his/her station.

After completing the config file, you can
start LinBPQ from the command line by running:
~/linbpq/.linbpq

Depending on your station setup, you may
need to start rig control, direwolf, or
other applications before running LinBPQ.

If you need help, you can find
the LinBPQ forums at
