The operating controls of the
KCU 951 are described as follows:
ON/OFF/Volume

controls the audio output level.
Squelch
Squelch Control provides variable
squelch threshold control.
Clarifier
Clarifier Control provides up to
250Hz of local oscillator adjustment
during the receive mode of operation
only. This function is performed by
varying the master reference oscilla-
tor frequency. Means are provided to
disengage the clarifier function by
pushing the adjust knob in.
Mode
The emission mode switch is a
momentary pushbutton that selects
LSB, AME, USB or optional A3A.
Emissions mode selection is cyclic
moving from left to right. This switch
is active at all times except transmit.
A3A is indicated by displaying the AM
and USB messages simultaneously.
Freq/Chan
This switch transfers the HF
System from a direct frequency
operation to a channelized form of
operation. The switch operates as a
two position switch. The depressed
position establishes the channelized
form of operation.
