The bargraph segment meter above the MAIN VFO-
A frequency display serves as a triple mode enhanced
tuning scale. By default, it displays relative Clarifier off-
set, and as you rotate the CLAR knob (either Rx or Tx
Clarifier), the normally centered marker segment
moves left or right, indicating the relative displaced
("clarified") Rx or Tx frequency from the original. Be
sure to see page 49 for more details on Clarifier op-
eration.
When the VRF feature is engaged, the segments
briefly indicate the peak position for the narrow band-
pass "preselector" when you are turning the VRF/MEM
CH knob. Be sure to see page 44 for more details on
VRF operation.
Alternately, you can have the segments expand
outwardly as you tune either direction from the nearest
displayed frequency. This lets you view tuning incre-
ments smaller than 10 Hz (the maximum display reso-
lution).
The rate and distance of segment displacement in
either mode are proportional to the selected tuning step
size and depend on whether or not the [ FAST ] button
is engaged. The tuning meter mode is selected by
selection 3-2.

YNCHRONOUS
Audio distortion of AM stations due to carrier fading
is common. Synchronous tuning reduces this phenom-
enon by receiving the station in "LSB" while re-inject-
ing an unfading carrier. The benefit of this technique is
that the re-injected carrier is phase-locked to carrier of
the original station, reducing the effects of fading and
improving signal fidelity over that of conventional AM
detection.
To activate AM synchronous detection, press the
[ AM ] button twice (so the green LED inside the button
blinks). The tuning meter format changes to that be-
low. Slowly tune across the signal until the lone center
segment appears (see below).

The small window to the right of the main frequency
display can contain several different readouts, selected
by menu selection 3-5 .
These include:
Clarifire - Displays "clari-
fied" frequency as offset from
the original frequency.
Channel Freq. - Displays
the operating frequency con-
tained in the current memory
channel providing "What if?" information while you are
operating on a VFO.
Offset - Displays the fre-
quency difference between the
Main VFO and Sub VFO fre-
quencies.
A1 (CW) Pitch - Displays
the current CW pitch setting.
Whichever selection you choose, if you activate the
Clarifier during operation, its display will over-ride any
other (non-Clarifier) settings you may have set via
selection 3-5.
