NB Switch
This button turns the IF Noise Blanker on and off.
Press this button momentarily to reduce a short-dura-
tion pulse noise; the “
” icon will appear in the dis-
play.
Press and hold in this button for one second to reduce
a longer-duration man-made pulse noise; the “
”
icon will blink for three seconds, then will appear con-
tinuously in the display.
Press this button again to disable the noise blanker;
the “
” icon will disappear.
A
DVICE
:
When you press (or press and hold) the [ NB
] button
momentarily, it affects the Main band (VFO-A) re-
ceiver. When you press the [
B
] button, then press (or
press and hold in) the [
NB
] button (within five sec-
onds of pressing the [
B
] button), it affects the Sub band
(VFO-B) receiver.
METER Switch
This control switch determines the function of the meter
during transmission.
COMP : Indicates the speech compressor level (SSB
mode only).
ALC : Indicates the relative ALC voltage.
PO : Indicates the average power output level.
SWR : Indicates the Standing Wave Ratio (Forward:
Reflected).
ID : Indicates the final amplifier drain current.
VDD : Indicates the final amplifier drain voltage.
MONI PROC Knobs
MONI Knob
The inner [ MONI
] knob adjust the audio level of the
transmit monitor during transmission (relative to the
AF GAIN control), when activated by the [
MONI
]
button.
PROC Knob
The outer [ PROC
] knob sets the compression (input)
level of the transmitter Speech Processor in the SSB,
AM, and FM modes, when activated by the [
PROC
]
button.
A
DVICE
:
The Sub band (VFO-B) frequency display will show
the compression level of the Speech Processor for 3
seconds whenever the outer [
PROC
] knob is turned.
You may disable this feature (displaying the compres-
sion level) via Menu item “
015 diSP LVL IND .” See
page 117 for details.
BK-IN Switch
This button turns the CW break-in capability on and
off. While the CW break-in is activated, the “
”
icon appears in the display.
SPOT Switch
This button turns on the CW receiver spotting tone; by
matching the SPOT tone to that of the incoming CW
signal (precisely the same pitch), you will be “zero
beating” your transmitted signal on to the frequency of
the other station.
The Sub (VFO-B) frequency display will indicate the
offset tone frequency when this button is pressed.
SPEED PITCH Knobs
SPEED Knob
The inner [ SPEED
] knob adjusts the keying speed of
the internal CW keyer (4 ~ 60 WPM). Clockwise rota-
tion increases the sending speed.
When turning this knob while pressing the [
KEYER
]
button, the Sub (VFO-B) frequency display shows the
keying speed.
A
DVICE
:
The Sub band (VFO-B) frequency display will show
the keying speed for 3 seconds whenever the inner
[
SPEED
] knob is turned.
You may disable this feature (displaying the keying
speed) via Menu item “
015 diSP LVL IND .” See page
117 for details.
PITCH Knob
The outer [ PITCH
] knob selects your preferred CW
tone pitch (from 300 ~ 1050 Hz, in 50 Hz increments).
The Tx sidetone, receiver IF passband, and display
offset from the BFO (carrier) frequency are all affected
simultaneously. The Pitch control setting also affects
the operation of the CW Tuning Indicator, as the cen-
ter frequency of the CW Tuning Indicator will follow
the setting of this control.
A
DVICE
:
The Sub band (VFO-B) frequency display will show
the CW tone pitch frequency for 3 seconds whenever
the outer [
PITCH
] knob is turned.
You may disable this feature (displaying the CW tone
pitch frequency) via Menu item “
015 diSP LVL IND .”
See page 117 for details.
NB SQL Knobs
NB Knob
The inner [ NB
] knob adjusts the noise blanking level
when the (analog) IF noise blanker is activated by press-
ing the [
NB
] button.
SQL Knob
The outer [ SQL
] knob sets the signal level threshold
at which the Main (VFO-A) receiver audio is muted,
in all modes. It 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.
