LSB, USB, CW, AM, FM, RTTY, PKT Button
Pressing the LSB , USB , CW , AM , FM ,
RTTY , or PKT button will select the operating
mode. Pressing the CW , AM , RTTY , or
PKT button multiple times will switch between the
alternate operating features that can be used on these
modes (covered later). Also, when you press and hold
in the PKT button for one second, the user-pro-
grammed custom function setting mode will be acti-
vated.
QMB (Quick Memory Bank) Switch
STO (Store) Button
Pressing this button copies operating information (fre-
quency, mode, bandwidth, and also repeater direction/
shift frequency and CTCSS functions on the FM mode)
into consecutive QMB Memories.
RCL (Recall) Button
Pressing this button recalls one of up to five Quick
Memory Bank memories for operation.
NAR (Narrow) Switch
In the SSB/CW mode, this button is used to set the
bandwidth of the DSP IF filters to a user-programmed
bandwidth (default values are SSB: 1.8 kHz, CW/
RTTY/PSK: 300 Hz, AM: 6 kHz). When NAR has
been engaged, the WIDTH knob will be disabled.
In the AM mode, this button is used to toggle the
receiver’s bandwidth between wide (9 kHz) and nar-
row (6 kHz).
In the FM mode on the 28 MHz and 50 MHz bands,
this button is used to toggle the FM deviation/band-
width between wide (± 5.0 kHz Dev./25.0 kHz BW)
and narrow (± 2.5 kHz Dev./12.5 kHz BW).
Pressing the A or B button (located above the
MODE selection buttons) will select either the VFO-
A or VFO-B for individual bandwidth setting.
Advice
When NAR has been engaged, the WIDTH knob
will be disabled, although IF Shift still works normally.
SPLIT Switch
Pressing this button to activates split frequency opera-
tion between the VFO-A, used for transmission and
VFO-B, used for reception. The same name LED lo-
cated at the right of the main tuning knob glows orange
while this function is active.
If you press and hold in the SPLIT switch for two
seconds, the “Quick Split” feature will be engaged,
whereby the VFO-B will automatically be set to a fre-
quency 5 kHz higher than the VFO-A frequency, and
the transceiver will be placed in the Split mode.
TXW “TX Watch” Switch
Pressing this key lets you monitor the transmit fre-
quency when split frequency operation is engaged.
When receiving on the transmit frequency, the LED
indicator will glow green. Press this key again to re-
turn to normal operation.
RX Indicator/Switch
This switch, when pressed, engages the VFO-A ; the
indicator will glow Green when the VFO-A is active.
When the VFO-A is active, pressing this button mo-
mentarily will mute the receiver, and the indicator will
blink. Pressing the button once more will restore re-
ceiver operation, and the indicator will glow Green
steadily.
TX Indicator/Switch
When this button is pushed, the indicator will glow
Red, and the transmitter will be engaged on the same
frequency and mode as was set up for the VFO-A (sub-
ject to any Clarifier offset, of course).
Advice
If this indicator is not illuminated, it means that the
VFO-B TX indicator has been selected (it will be glow-
ing Red). In this case, transmission will be effected
on the frequency and mode programmed for the VFO-
B.
Main Dial Knob
This large knob adjusts the operating frequency of the
VFO-A or a recalled memory. Clockwise rotation of
this knob increases the frequency. Default tuning in-
crements are 10 Hz (100 Hz in AM and FM modes);
when the FAST switch is pressed, the tuning steps
increase. The available steps are:
Operating Mode 1 Step* 1 Dial Rotation
LSB/USB/CW/RTTY/PKT(LSB) 10 Hz (100 Hz) 10 kHz (100 kHz)
AM/FM/PKT(FM)
100 Hz (1 kHz) 100 kHz (1 MHz)
*Numbers in parentheses indicate steps when the [FAST] switch is On.
Advice
The tuning steps for the Main Tuning Dial (de-
scribed in this section) are set, at the factory, to 10 Hz
per step. Via Menu item “
TUNING 129 MAIN DIAL
STEP ,” however, you may change this setting from
10 Hz to 1 Hz instead. When 1 Hz basic steps are
selected, the action of the FAST button (#
be-
low) will be changed to 1/10 of the values listed above.
FAST Switch
Pressing this button will increase or decrease the tun-
ing rate of the Main Tuning Knob (#
above) by
a factor of ten, as mentioned in the previous section.
When this function is activated, the LED inside the
button will glow red.
LOCK Switch
This button toggles locking of the main tuning knob,
to prevent accidental frequency changes. When the
button is active, the Main Tuning Knob (#
, de-
scribed previously) can still be turned, but the fre-
quency will not change, and the LED inside the but-
ton will glow red.
