FT-920 Operating Manual
82
U-66 (
VX-ANTR
)
Function: Set the level of the “Anti-Trip” circuitry of
the VOX system
Available Values:
0
~
15
Default:
15
This adjustment scale is also arbitrary. This Menu
Item should be set to the point where loud speaker
volume does not activate the VOX.
U-67 (
Q MENU
)
Function: Define which items are to be included in
the “Quick Menu” bank
Available Values: All Menu Items
Default: OFF
After pressing [E
NT
] while using this Menu Item, ro-
tate the VFO-B Tuning Dial to select the Menu Item
to be included/excluded from Quick Menu, then use
the front panel [U
P
p
] or [D
OWN
q
] key to change the
setting for that Menu Item to ON or OFF.
The default setting for this Menu Item is OFF, which
means that there is no Quick Menu feature active.
When this is the case, a momentary press of the
[M
ENU
] key activates “Normal Menu” operation. When
one or more items have been designated for “Quick
Menu” use, however, a momentary press of [M
ENU
]
activates the Quick Menu; pressing and holding
[M
ENU
] in for ½ seconds activates “Normal menu”
operation in this case.
U-68 (
FM STEP
)
Function: Set scanning steps/ to be used during FM
operation
Available Values:
OFF
/
0.5
~
50
kHz
Default:
10
kHz
This Menu Item sets the scanning steps for FM work
when the “FAST” synthesizer-step mode is selected.
It allows the radio to be used in a “channelized” mode
according to the channel spacing utilized in your coun-
try.
U-69 (
CW-NAR
)
Function: Enable/Disable the signal path through the
optional YF-116C CW filter
Available Values:
on
/
oFF
Default:
oFF
When the CW filter is installed, the signal path must
be enabled (or the FT-920 will not “know” that the
filter is there). Conversely, if the filter is not installed,
erroneously setting this Menu Item to “
on
” will re-
sult in a “dead” receiver if the [N
ARROW
] key is pressed
during CW operation.
U-70 (
AM-WIDE
)
Function: Enable/Disable the signal path through the
optional YF-116A AM filter
Available Values:
on
/
oFF
Default:
oFF
When the AM filter is installed, the signal path must
be enabled (or the FT-920 will not “know” that the
filter is there). Set this Menu Item to “
on
” to enable
the signal path to the Wide filter. The stock 2.4 kHz
(SSB) filter then becomes the “Narrow” filter during
AM operation.
U-71 (
AUTOTUN
)
Function: Enable/Disable automatic retuning of ATU
settings when SWR increases
Available Values:
on
/
oFF
Default:
on
This feature instructs the Automatic Antenna Tuner
to re-adjust its settings, without operator intervention,
should the SWR present at the antenna jack increase
above a value of 3:1.
U-72 (
FASTTUN
)
Function: Enable/Disable high-speed antenna tun-
ing
Available Values:
on
/
oFF
Default:
oFF
The higher-speed tuning option reduces the tuning
time slightly for the ATU. The SWR obtained at the
completion of “Fast” tuning may be slightly higher than
in the “Normal” mode, but this should present no prob-
lems in typical operation.
