TUNE Switch
This is the on/off switch for the FT-2000D's Auto-
matic Antenna Tuner.
Pressing this button momentarily places the antenna
tuner in line between the transmitter final amplifier and
the antenna jack ("
play). Reception is not affected.
Pressing and holding in this button for 1/2 second, while
receiving in an amateur band, activates the transmitter
for a few seconds while the automatic antenna tuner
rematches the antenna system impedance for minimum
SWR. The resulting setting is automatically stored in
one of the antenna tuner's 100 memories, for instant
automatic recall later when the receiver is tuned near
the same frequency.
Pressing this button momentarily, while the Tuner is
engaged, will take the Automatic Antenna tuner out of
the transmit line.
N :
When the Automatic Antenna Tuner is tuning itself, a
signal is being transmitted. Therefore, be absolutely
certain that an antenna or dummy load is connected to
the selected antenna jack before pressing and holding
in the [ TUNE ] button to start antenna tuning.
PHONES Jack
A 1/4-inch, 3-contact jack accepts either monaural or
stereo headphones with 2- or 3-contact plugs. When a
plug is inserted, the loudspeaker is disabled. With ste-
reo headphones such as the optional YH-77STA, you
can monitor both Main (VFO-A) and Sub (VFO-B)
receiver channels at the same time during Dual Re-
ceive operation.
N :
When wearing headphones, we recommend that you
turn the AF Gain levels down to their lowest settings
before turning power on, to minimize the impact on
your hearing caused by audio "pops" during switch-
on.
KEY Jack
This 1/4-inch, 3-contact jack accepts a CW key or keyer
paddles (for the built-in electronic keyer), or output
from an external electronic keyer. Pinout is shown on
page 15. Key up voltage is 5 V, and key down current
is 1 mA. This jack may be configured for keyer, "Bug,"
"straight key," or computer keying interface operation
via Menu item "052 A1A F-TYPE" (see page 121).
There is another jack with the same name on the rear
panel, and it may be configured independently for In-
ternal Keyer or pseudo-straight-key operation.
N :
You cannot use a 2-contact plug in this jack (to do so
produces a constant "key down" condition).

Microphone Connector

This 8-pin jack accepts input from a microphone uti-
lizing a traditional YAESU HF-transceiver pinout.
DIM Switch
Press this button to lower the illumination intensity of
the analog meter and the frequency display. Press it
once more to restore full brightness.
A :
Menu Items "008 diSP DIM MTR" and "009 diSP
DIM VFD" allow you to configure the dimming levels
for the analog meter and the frequency display inde-
pendently, so you can customize the brightness levels.
VOX Switch
This button enables automatic voice-actuated transmit-
ter switching in the SSB, AM, and FM modes. While
activated, the LED inside this button glows red. The
controls affecting VOX operation are the front panel's
[ VOX ] and [ DELAY ] knobs. By proper adjustment of
these controls, hands-free voice-actuated operation is
possible.
ANTENNA Select Switch
[ 1/2 ] : Pressing this selects either the ANT 1 or 2 jack
on the rear panel, and allows convenient antenna
switching at the press of button. The selected antenna
jack is indicated at the upper left corner of the display.
[ RX ] : Normally, the antenna connected to the ANT 1
or 2 jack is used for receive (and always used for trans-
mit). When the [ RX ] switch is pressed, an antenna con-
nected to the RX ANT will be used during receive.
MONI Monitor Switch
This button enables the transmit monitor in all modes.
While activated, the "
play. Adjustment of the Monitor level is accomplished
using the [ MONI ] knob.
A :
When using headphones, the Monitor is highly useful
for making adjustments to the Parametric Equalizer or
other voice quality adjustments, because the voice qual-
ity heard in the headphones is such a "natural" repro-
duction of the transmitted audio quality.
