UNING THE
Tuning is accomplished in several ways, with each
method having its own advantages; they are:
¦ Main & Sub VFO Knob Tuning
¦ Shuttle Jog Tuning
¦ Panel & Microphone Down/Up keys
¦ VFO Channel Stepping
VFO Knob
Rotating the Main
VFO-A knob tunes
the transceiver ac-
cording to the se-
lected tuning step
size and encoder
tuning rate. Both of
these settings are
configured via menu
selections 1-3 & 1-4
(see page 99). The
table below shows
the available tuning step sizes and their default set-
tings.

For faster dial tuning rates with either the VFO knob
or mic UP/DOWN buttons, press the [ FAST ] button
below and to the left of the Main VFO knob ("FAST"
appears). This selects the VFO speed, which can be
switched between 4x (default) and 2x in menu selection
1-0 (see page 99). This affects the
rotation without changing the default tuning step size.

Shuttle Jog
The Shuttle Jog ring is more efficient for large fre-
quency excursions, or whenever QSY requires spin-
ning the VFO knob a lot, while still providing positive
control with a comfortable feel.
R o t a t i n g t h e
Shuttle Jog away
from the center de-
tent in either direction
starts constant tun-
ing. The farther the
S h u t t l e J o g i s
moved from center,
the larger the pro-
gressive frequency
steps (and QSY).
There are 13 preset
frequency steps incrementing through the arc of the
Shuttle Jog (from 10 Hz ~ 100 kHz). The Shuttle Jog
speed (encoder rate) is also configurable from 1 ~ 100
msec. via menu selection 1-1 on page 99.
Recall that the step size varies as the Shuttle Jog
is turned, while the encoder rate is fixed. The effect of
tuning faster as the Shuttle Jog is rotated actually
comes from jumping to progressively larger tuning in-
crements, as encoder rate remains constant.
FAST Button Operation
By default, the front panel [ FAST ] button is a press-
on, press-off type. However, you can change it to a
momentary type by recalling menu selection 8-0 (see
page 104) and changing the default setting.
