AGC Switch
Move this knob up and down to select the receiver AGC
characteristics (receiver-recovery time). Available se-
lections are FAST, MID, SLOW, or AUTO, and the
selected receiver-recovery time appears in the AGC
column of the Block Diagram Display.
Hold this knob up or down for two seconds to disable
the AGC (for testing or weak-signal reception).
A
:
Press this knob in briefly to quickly select "AUTO".
If the AGC is disabled by holding the [ AGC ] knob
up or down, the S-meter will no longer deflect. Ad-
ditionally, you will likely encounter distortion on
stronger signals, as the IF amplifiers and the fol-
lowing stages may be overloaded.
METER Switch
This control switch determines the function of the meter
during transmission.
COMP: Indicates the speech compression level (SSB
mode only).
Indicates the relative ALC voltage.
ALC:
Indicates the average power output level.
PO:
Indicates the Standing Wave Ratio (Forward:
SWR:
Reflected).
Indicates the final amplifier drain current.
ID:
Indicates the final amplifier drain voltage.
VDD:
MONI
PROC Knobs
[ MONI ] Knob
The inner [ MONI ] knob adjusts the audio level of
the transmit RF monitor during transmission (rela-
tive to the AF GAIN control), when activated by
the [ MONI ] button.
[ PROC ] Knob
The outer [ PROC ] knob sets the compression (in-
put) level of the transmitter Speech Processor in
the SSB, AM, and FM modes, when activated by
the [ PROC ] button.
A
:
The relative compression level of the Speech Pro-
cessor will show for 3-seconds in the lower right
corner of the Main Display whenever the outer
[ PROC ] knob is turned.
Alternately, the 3-second display feature may be
changed to show in the SUB DISPLAY-
dow via Menu item "018 DISP INDI". Addition-
ally, you may disable the 3-second display feature
via Menu item "017 DISP LVL IND" See page
122 for details.

VFO-B NB
[ NB ] Knob
The inner [ NB ] knob adjusts the noise blanking
level when the VFO-B (analog) IF noise blanker is
activated by pressing the [ NB ] button.
[ SQL ] Knob
The outer [ SQL ] knob sets the signal level thresh-
old at which the VFO-B receiver audio is muted, in
all modes. The squelch is very useful during local
rag-chews, to eliminate noise between incoming
transmissions. This control is normally kept fully
counter-clockwise (off), except when scanning and
during FM operation.
VFO-A NB
[ NB ] Knob
The inner [ NB ] knob adjusts the noise blanking
level when the VFO-A (analog) IF noise blanker is
activated by pressing the [ NB ] button.
[ SQL ] Knob
The outer [ SQL ] knob sets the signal level thresh-
old at which the VFO-A receiver audio is muted, in
all modes. The squelch is very useful during local
rag-chews, to eliminate noise between incoming
transmissions. This control is normally kept fully
counter-clockwise (off), except when scanning and
