This data are sending to DAC to provide correction of
voltage to Digisonde

general clock Oven Controlled 61.44
MHz Oscillator. This is DCART Global parameter. It need
to be tuned for every particular Digisonde

.
Controlling address for DESC to command is 0x2C.
It is two possible ways to command:
First - command byte 0x01, data XX
Second - command byte 24, data XX
or
First - command byte 0x05, data XX
Second - command byte 20, data XX

Trackers Calibration Data packet TYPE=0x06, Payload length is variable
5:137. DCART sends the Load Tracker Calibration Data packet at the time of the connection. This packet con-
tains information needed for tuning hardware to any particular frequency.

Amplifier Half-Octave Filter Switch Frequencies Table TYPE=0x86, Payload length is variable
5:139. DCART sends the Amplifier Half-Octave Filter Switch Frequencies Table at the time of the connection.
This packet contains information needed to switch amplifier to the correct filter band for any particular fre-
quency.
