C E N T E R
sets the center frequency of the display,
which is also displayed at the top center of the
spectrum window when in tracking mode. If
MENU:CenterEn is set to OFF, then this function is
disabled for tracking mode. If the transceiver is a
K3, the center frequency defaults to the VFO A
frequency of the K3, but it may be tuned above and
below that value. It will then track any changes in
the K3’s VFO A.
In fixed-tune mode as well,
C E N T E R
sets the
center frequency of the display, however it does not
track the K3 VFO but stays at a fixed frequency. If
desired, you can set the center frequency to re-
adjust automatically by setting the proper mode in
MENU:FixMode In both fixed and tracking modes,
hold the
C E N T E R
key a second time to return the
center frequency to the K3's VFO A frequency.
R E F L V L
Sets the amplitude reference level of the
display, both spectrum and waterfall. The term
"reference level" means the signal level that
corresponds to the bottom of the spectrum display
and the minimum signal level (dark blue) of the
waterfall. The amplitude labels that appear along
the left edge of the spectrum display may be in dBm
or S-units plus dB over S9, depending on the setting
of MENU:Lvl Mode. If the transceiver is a K3, the
amplitude is that of the signal at the K3 antenna
input, with the state of the K3's attenuator and
preamp taken into account. Tap any key to de-select
the parameter entry.
S C AL E
Sets the scale, or range, of both the
spectrum and waterfall displays. For example, "60
dB" means that the bottom of the display is 60 dB
below the top. Tap any key to de-select the
parameter entry.
D I S P L AY
Toggles between the spectrum, and
combination spectrum/waterfall display modes.
A V E R AG E
Turns on display averaging and allows
adjustment of the averaging time, in units of the
display update period. To de-select parameter entry
and turn off averaging at the same time, hold the
key a second time. To de-select parameter entry
while leaving averaging turned on, tap the key.
Menu
MENU
Accesses an alphabetical list of functions
(see Menu Functions, page.33). Scroll through the
list with the SELECT knob and tap the knob to
select an item. For items with only two or three
values, tapping the SELECT knob toggles
between the parameter values. For other items, you
can turn the SELECT knob to choose the
parameter value. Tapping the knob a second time
un-selects the item and exits the menu. If you wish
to terminate the item but keep the menu active, tap
MENU
. When you wish to exit the menu, tap
MENU
again.
Programmable Function Keys
Most menu functions can be assigned to a function
key by tapping or holding the
F N 1
–
F N 4
or
F N 5
–
F N 8
key while the menu item is displayed but not
selected. The label for that function key will then
change to the function name (when labels are turned
on with the
L A B E L S
key).
L AB E L S
toggles the function key labels on and off.
Note that the function keys are still active even
when the labels are turned off.
