Main Dial Knob
This large knob adjusts the operating frequency of the
Main (VFO-A) Band or a recalled memory. Clockwise
rotation of this knob increases the frequency. Default
tuning increments 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 Dial (described 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 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 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 can still be
turned, but the frequency will not change, and the LED
inside the button will glow green.
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 main
band (VFO-A) or sub band (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 main band (VFO-A), used for trans-
mission and sub band (VFO-B), used for reception. The
same name LED located 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 Sub (VFO-B) band VFO will automati-
cally be set to a frequency 5 kHz higher than the Main
(VFO-A) band 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.
C.S Switch
Press this button momentarily to recall a favorite Menu
Selection directly.
To program a Menu selection as the short-cut, press
the MNU key to enter the Menu, then select the
item you want to set as the short-cut. Now press and
hold in the C/S key for two seconds; this will lock
in the selected Menu item as the short-cut.
A B Switch
Press this button momentarily to transfer data from the
main band (VFO-A) frequency (or a recalled memory
channel) to the sub band (VFO-B), overwriting any pre-
vious contents in the sub band (VFO-B). Use this key to
set both main band (VFO-A) and sub band (VFO-B)
receivers to the same frequency and mode.
B A Switch
Press this button momentarily to transfer data from
the sub band (VFO-B) frequency to the main band
(VFO-A), overwriting any previous contents in the
main band (VFO-A). Use this key to set both main
band (VFO-A) and sub band (VFO-B) receivers to
the same frequency and mode.
