SHIFT WIDTH Knobs
(except on FM mode)
SHIFT Knob
This knob provides adjustment of the IF DSP passband,
using 20 Hz steps for precise adjustment and easy re-
duction of interference on either side of your operating
frequency. The total adjustment range is ± 1 kHz.
The normal operating setting for this knob is straight
up, in the 12 o'clock position.
WIDTH Knob
The outer WIDTH knob, when turned to the 12
o'clock position, sets the overall IF bandwidth of the
main band (VFO-A) receiver to its maximum band-
width. Turning the WIDTH knob either direction,
reduces the overall IF bandwidth of the main band
(VFO-A) receiver.
When the NAR (Narrow) filter selection is engaged,
this control is disabled. The SHIFT control, how-
ever, is still fully functional.
Use this control to narrow the IF DSP passband, as
necessary, to reduce interference. The SHIFT con-
trol may be used to re-center the passband response
on the incoming signal, and you may find that the
CONTOUR and IF NOTCH filters may also help im-
prove intelligibility and/or reduce interference. See
also the discussions of controls CONT (#
scribed previously), DNR (#
ously), and VRF/µ (#
Advice
When the NAR switch (#
has been pushed, the WIDTH control no longer
functions. The IF SHIFT system is still fully opera-
tional, however.
ACM (Adjacent Channel monitor) Switch
(CW Mode)
When using a narrow bandwidth, such as 300 Hz, on the
Main (VFO-A) band receiver in the CW mode, pressing
the ACM switch will take over the Sub (VFO-B) band
receiver, and utilize it for monitoring the signal strength
of any signals being received inside a 2.4 kHz window
centered on your current operating frequency. You will
not hear any of the interfering signals, but their signal
strength will appear on the Sub (VFO-B) band S-meter.
RX Indicator/Switch
This is the switch that turns the Sub (VFO-B) receiver
On and Off. When this button is pressed to make the
Sub (VFO-B) receiver active, the Green LED imbed-
ded within the switch will light up. Pressing the switch
again will disable this receiver, and the imbedded
Green LED will turn off.

TX Indicator/Switch
This is the switch that turns the Sub (VFO-B) trans-
mitter On and Off. When this button is pressed to trans-
fer transmitter control to the Sub (VFO-B) frequency
and mode, the Red LED imbedded within the switch
will light up. Pressing this switch once more will trans-
fer frequency/mode control back to the Main (VFO-
A) side, and the Red LED imbedded within this switch
will turn off.
CLAR (Clarifier) Switch
When this switch is pushed, the CLAR/VFO-B knob
(# , described later) will be enabled for the purpose
of utilizing the CLAR/VFO-B knob as an "Offset
tuning" control to allow tuning away from the Main
(VFO-A) frequency.
BAND/MHz Switch
BAND Switch
Pressing this button momentarily allows you to select
the main (VFO-A) operating band (Amateur bands)
using the CLAR/VFO-B knob (#
later).
MHz Switch
Pressing and holding in this button for 2 seconds al-
lows you to tune the main band (VFO-A) frequency
down or up in 1 MHz increments, using the CLAR/
VFO-B knob (# , described later).
B-DISP OFF Switch
Pressing this button causes the Sub (VFO-B) band fre-
quency to be blanked out, for local rag-chews or other
occasions when the additional display information is
not needed. When this function is activated, the LED
inside the button will glow green.
MCH/GRP Switch
MCH Switch
Pressing this button momentarily allows you to select
the memory channel using the CLAR/VFO-B knob
(# , described later).
GRP Switch
Pressing and holding in this button for 2 seconds al-
lows you to select the memory group using the CLAR/
VFO-B knob (# , described later).
