TRACKING DATA
The radio personality contains certain
information bytes known as Tracking Data, which allow
the radio computer to calibrate transmitter power ,
modulation deviation and squelch threshold. Normally, no
adjustments need be made to the radio to maintain
specified limits for the above parameters, since the radio
computer makes the necessary adjustments using the
Tracking Data established at the factory. However, should
the transmitter PA, synthesizer or logic circuit boards be
replaced, it may be necessary to alter the Tracking Data to
re-set these parameters properly. Furthermore, if the
Tracking Data is lost, specialized procedures are required
to load new Tracking Data. Therefore, it is VERY
IMPORTANT to establish a record of the Tracking Data
of every radio as it is received from the factory. The
frequencies at which Tracking Data is established are
given in the "Test Frequencies" section.
TEST FREQUENCIES
The following frequencies are those for which
Tracking Data is established and are used as Test
Frequencies:
