NAME
frq - frequency files for the ESR
SYNOPSIS
/opt/esr0/exp/name/name.frq
DESCRIPTION
This file is the description of the frequencies that will be
downloaded to the ESR exciter by the loadxc program.
The program will ignore lines beginning with # or empty
lines
Each remaining line will consist of three numbers, separated
by blanks, which represent the unit, location and frequency,
respectively. The unit will be 0, 1, 2 or 3, and represents
which of the independent Direct Digital Synthesis (DDS)
units that will use this particular frequency. location
will be from 0 to 15, and says which of the 16 pre-
programmed frequencies (for each unit) we're defining.
frequency is the requested transmit freqency in mHz. The
transmitter center frequency will be 500000000000. The
maximum accuracy of the DDS running on 60 MHz is 14 mHz.
EXAMPLES
These lines are taken from the gup0 frequency file. Only
the first few locations of each unit is used, and only those
lines are shown.

Previous versions of the frequency file had several more
coloumns of numbers. These coloumns are no longer read.
