Vc Tune; Fine Tune The Tuning Point; Custom Select); How To Assign Functions - Yaesu FTDX101D Operation Manual

VC TUNE

The VC tuning circuit drives the variable capacitor
in the receiver RF front end with a high precision
stepping motor, and effectively attenuates the
strong intruding signals that are particularly prob-
lematic in the low band. If there are multiple dis-
turbing signals, turning the MPVD ring allows fine
tuning of the VC tuning point.
1. Press the [VC TUNE] operation key.
● When the VC Tune is active, the LED lights red
and a bar graph representing the position of the
VC Tuning frequency is displayed in the filter
function display.
● The VC tune circuit will automatically align itself
to the operating frequency.
2. To exit from VC tune operation, press the [VC
TUNE] operation key.
When VC Tune operates, the display on the
Scope Screen also changes significantly be-
cause the RF sensitivity changes greatly.
Adjust the reference level with the [MULTI]
knob or turn the MPVD ring to make fine ad-
justments.

• Fine tune the tuning point

1. Press the [VC TUNE] key (located at the upper
right of the MAIN dial).
2. Rotate the MPVD ring to peak the response
(background noise) or reduce interference.
● Press and hold the [VC TUNE] operation key to
re-center the filter response on the current oper-
ating frequency.
When VC Tune operates, the steep attenu-
ation characteristics of VC Tuner may cause
some signals in the Spectrum Scope to be
attenuated and disappear, or the image may
not appear uniform, however this is not a
malfunction.
The VC-Tuning modules are available only
for the Main band. If you also want to use it
on the SUB band, please contact Yaesu.
The VC tune function works only with
amateur bands from 1.8 MHz band to
29 MHz.

The function selection screen is displayed.
2. Touch the function you want to assign.

MAIN/SUB

When the MAIN/SUB key is pressed, the MPVD
ring tunes the SUB band frequency. When oper-

SUB band. the ring tunes the frequency of the
MAIN band.
