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.

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