Adjusts The Vox Gain; Adjusts The Vox Delay Time; Adjusts The Vox Anti-Trip Sensitivity - Yaesu FTDX101D Operation Manual

TUNE
This is the ON/OFF switch for the FTDX101D Auto-
matic Antenna Tuner.
Press the [TUNE] key briefly to activate the antenna
tuner. Press the [TUNE] key briefly again to disable
the antenna tuner.
Press the [TUNE] key for about 1 second to start
"automatic tuning".
Since the transceiver transmits automati-
cally during automatic tuning, make sure to
connect an antenna or dummy load before
tuning up.
When the antenna or dummy load does not
match the impedance, "HI-SWR" will appear
on the touch panel.
VOX
This key enables automatic voice-actuated trans-
mitter switching. While VOX is activated, the LED
inside this key glows orange.
1. Press the [VOX] key.
VOX feature is activated
2. Without pressing the PTT switch, speak into the
microphone in a normal voice level. When you
start speaking, the transmitter should be activat-
ed automatically.
When you finish speaking, the transceiver
should return to the receive mode (after a short
delay).
To cancel VOX and return to PTT operation,
press the [VOX] key once more.

• Adjusts the VOX GAIN

The VOX Gain may be adjusted to prevent unin-
tended transmitter activation in a noisy environ-
ment. To adjust the VOX Gain:
1. Press the [FUNC] key.
2. Touch [VOX GAIN] .
3. While speaking into the microphone, rotate the
[MULTI] knob to the point where the transmitter
is quickly activated by your voice, without back-
ground noise causing the transmitter to activate.

• Adjusts the VOX Delay Time

The "Hang-Time" of the VOX system (the trans-
mit-receive delay after the cessation of speech)
may also be adjusted.
To set a different delay time:
1. Press the [FUNC] key.
2. Touch [VOX DELAY] .
3. Rotate the [MULTI] knob while saying a brief syl-
lable like "Ah" and listening to the hang time for
the desired delay.

• Adjusts the VOX anti-trip sensitivity

The Anti-Trip setting sets the negative feedback
of receiver audio to the microphone, to prevent re-
ceiver audio from activating the transmitter (via the
microphone).
1. Press the [FUNC] key.
2. Touch [ANTI VOX] .
3. Rotate the [MULTI] knob to prevent receiver au-
dio from activating the transmitter (via the micro-
phone).
MOX
Pressing this key engages the PTT (Push to Talk)
circuit to activate the transmitter.
ZIN/SPOT
ZIN
Press the [SELECT] switch momentarily to adjust
the receiving frequency and zero-in automatically
while receiving a CW signal.
SPOT
While pressing and holding [SPOT], the tone is
output from the speaker. This tone corresponds to
the pitch of your transmitted signal. If you adjust the
receiver frequency until the pitch of the received
CW signal matches that of the Spot tone, the trans-
mitted signal will be precisely matched to that of the
other station.
SD memory card slot
You can use the commercially available SD memo-
ry card to save various settings, save the memory
contents, screen capture and update the firmware.
• The SD card is not provided with the prod-
uct.
• Not all SD cards sold commercially are
guaranteed to work with this transceiver.
