23.MAIN VFO-A Tuning Knob
This large knob adjusts the operating frequency of
Main VFO-A (or a recalled memory). Default tuning
increments are 10 Hz (100 Hz in AM and FM modes).
When the [ FAST ] button has been pressed, the incre-
ments are 10x these sizes. See the table on page 38
for a listing of all available steps.
24.Shuttle Jog and VRF & IDBT Buttons
The Shuttle Jog ring allows fine or rapid frequency
excursions with just a slight turn of your hand. Rotating
the ring slightly either to the left or the right tunes down-
ward or upward a few steps. The tuning rate increases
the farther the ring is rotated.
Pressing the [ VRF ] button on the left side of the
Shuttle Jog activates the VRF (Variable RF Front-end
Filter), which adds a narrow input preselector filter into
the RF receiver circuit on the 160-20 meter Amateur
bands. Its passband can be tuned by rotating the VRF/
MEM CH knob, located on the upper right corner of
the front panel, for maximum sensitivity and out-of-band
Pressing the [ IDBT ] button on the right side of the
Shuttle Jog activates the IDBT (Interlocked Digital
Bandwidth Tracking) System, which matches the EDSP
(Bandwidth) filter characteristics to the settings of the
SHIFT and WIDTH knobs. Thus, it is not necessary to
re-adjust the EDSP settings if you change the (IF)
WIDTH and/or SHIFT settings; the EDSP settings will
automatically follow those of the higher-frequency IF
This button toggles locking of the main tuning knob
to prevent accidental frequency changes. "LOCK" is
displayed in a red box below and to the left of the main
frequency display field when this command is active
(the tuning knob can still be turned, but it does noth-
ing). Press [ LOCK ] again to enable the tuning knob.
26.AF REV Button
Pressing this reverses the main/sub receiver audio
adjusted using the AF GAIN knob and SUB AF knob.
When activated, the LED inside this button glows red.
27. DOWN ( q ) & UP ( p ) Buttons
Pressing either of these buttons momentarily steps
the operating frequency down or up 100 kHz, respec-
tively. Pressing and holding the [ FAST ] button while
pressing one of these buttons steps the frequency down
or up 1 MHz. Continue holding either button for repeated

28. MAIN VFO-A [ RX & TX Switch-LED ]
These combination lamp-switches select and indi-
cate the transmit/receive status of the main tuning knob
and display. When the green "RX" lamp is lit, the re-
ceiving frequency is under control of the main knob
and display (either VFO-A or a recalled memory chan-
nel). When the red "TX" lamp is lit, the transmitting
frequency is under control of the main knob and dis-
play. Thus, for "normal" (non-split) operation, both the
red and green lamps associated with the main tuning
knob will be illuminated.
29. VFO/MEM Button
This button toggles main receiver operation between
the memory channel and the main VFO-A. Either
"VFO," "MEM," or "M TUNE" will be displayed to the
left of the main frequency display field to indicate the
current selection. If a displayed memory has been re-
tuned, pressing this button returns the display to the
original memory contents, and pressing it again returns
operation to the Main VFO.
30. [ M
A ] Button
Pressing this button momentarily displays the con-
tents of the currently-selected memory channel for three
seconds. Holding this button for ½ second copies the
data from the currently selected memory to the Main
VFO-A, as two beeps sound. Previous data in the Main
VFO will be overwritten.
31. QMB Buttons
[ RCL ] ( Recall ) - Recalls one of up to five Quick
Memory Bank memories for op-
[ STO ] ( Store ) - Pressing this copies operating pa-
rameters into consecutive QMB
32. [ DUAL ] Button
This button activates dual-channel reception with
the main and sub receivers. When this function is ac-
tive, "DUAL" will be displayed in a box at the left edge
of the display.
