[ ] Display Backlight:
Press and hold the
LOCK
button for approximately 3 seconds to toggle the display
backlight on or off.
FUNCTION MENU:
Many of the X5105’s advanced features are accessed via the Function Menu. Use this
section of the manual to “walk through” and become familiar with each one.
FUNCTION MENU PAGES:
The Function Menu has nine pages (
M1-M9
), with three or four entries per page.
The current page number is displayed in a box at the lower-left corner of the display screen. To change the
page, press
MENU
and the page number will blink. Rotate the
VFO
encoder to select a new page number,
then press
MENU
again to lock it in. The menu is circular, stepping
M1
to
M9
.
SOFT KEYS:
The four buttons at the bottom of the display screen are called
Soft Keys
. Each one will be
labeled with a two or three letter designator appearing above it on the screen. Labels for the soft keys
change with each new page.
Menu Page-1 [M1]
[ ] A=B:
Press to copy all parameters stored in
VFO-A
over to
VFO-B.
Parameters may include band,
frequency, operating mode, etc. After entry, the
VFO-A
or
VFO-B
settings may be modified, as needed.
[ ] SPL
(Split)
:
Press
SPL
to initiate automatic split-frequency operation. In this mode, you may tune around
using
VFO-A
, but when you transmit, the radio automatically switches to the settings you’ve retained in
VFO-B
(an important DX operating aid).
[ ]
NR
(Digital Noise Reduction)
:
This function activates and sets the radio’s digital noise-reduction level.
Press
NR
and
the
current
NR-Level
will appear on the display with a number from
0
and
10
. Use the
VFO
encoder knob to alter the noise reduction level. When set for
0
, the
NR
circuit is
off
. When set between
1-10
,
it is
on
. The
NR
status indicator appears on-screen to the right of the AGC icon.
To adjust, listen to incoming signals and rotate the
VFO
encoder for the most comfortable processing level.
Five seconds after your last entry, the encoder will revert back to normal VFO operation. Digital Noise
Reduction works well for general QRN, static crashes, splatter, powerline noise, etc. Setting
1
delivers
minimum processing, and
10
the maximum.
Set to
0
to turn the function off.
Note that
NB
impulse blanking
may work better for pulsed noises such as auto ignitions and electric fences.
[ ] NTH
(Notch Filter): Used to reduce or eliminate unwanted carriers and noise bands. Press
NTH
to
engage.
When set to
0
,
the filter is off and out of the circuit.
When set from
1-100
, it is on. Adjust the
VFO
encoder to position the notch for minimum interference. Once set, normal VFO operation will be restored
after 5 seconds. The notch filter has no on-screen status icon but
should be left off (
0
) unless needed.
