Receiver Control Operator Controls and Instruments
Control or instrument
-------- --. -- -- -- --.----..----------
Allows monitoring of receiver audio.
Controls audio out-put level.
Allows the receiver control operator to control gain
of receiver IF stages,
Provides fine tuning resolution of 100 Hz when receiver
control is in single sideband (ssb) operation.
Provides a noise threshold (squelch) level which the
received signal must exceed to provide a video and
audio output. In off position, all received audio
(and noise) is output 6 by the receiver
Provides automatic gain control to prevent a strong
signal from overdriving the IF stages of the receiver.
Allows the IF stage gain of the receiver to be manu-
ally controlled by MGC.
Allows limited manual control of receiver IF gain
using MGC control (Age function takes over when re-
ceived signal strength is excessive).
Turns on internal receiver test signal for intercept
subsystem BITE test
8 KHZ BW
Sets receiver bandwidth at 8 kHz.
Sets receiver bandwidth at 30 kHz.
30 KHZ BW
Sets receiver bandwidth at 50 kHz.
50 KHZ BW
*Momentary switch operation (operates only while key is pressed).
