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.

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 052 A1A F-TYPE" (see page 117).

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.

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.

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 the SSB,
CW, AM, and FM modes. While activated, the "
icon appears in the display. Adjustment of the Monitor
level is accomplished using the [ MONI ] knob.

DVICE
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.
PROC ( Processor ) Switch
This button enables the Speech Processor for SSB
transmission. While activated, the "
in the display. Adjustment of the Processor level is ac-
complished using the [ PROC ] knob.
A :
DVICE
The Speech Processor is a tool for increasing the
average power output through a compression tech-
nique. However, if the [ PROC ] knob is advanced
too far, the increase in compression becomes
counter-productive, as intelligibility will suffer. We
recommend that you monitor the sound of your sig-
nal using the Monitor (with headphones).
When the optional DMU-2000 Data Management
Unit is connected, you may use the Audio Scope/
Oscilloscope page to help you adjust the setting of
the compression level of the Speech Processor for
optimum performance using your voice and micro-
phone.
KEYER Switch
This button toggles the internal CW keyer on and off.
While activated, the "
play. The Keyer sending speed and the CW Hang Time
are adjusted via the front panel's [ SPEED ] and [ DE-
LAY ] knobs.
