Installation and Interconnections
Antenna Considerations
The FT-710 is designed to connect to a 50 Ohm resistive impedance antenna at the Amateur operating
frequencies. Select an appropriate antenna (dipole antenna, YAGI antenna, cubical quad antenna, etc.)
that is suitable for the chosen operation and bands.
Construct the antenna and coaxial cable, or use a suitable antenna tuner, to maintain the impedance
presented to the FT-710 antenna connector for an SWR of 1.5 or less. Careful preparation of the antenna
and/or tuner will permit maximum performance, and protect the transceiver from damage.
High transmitter RF voltages may be present on the antenna; install it so it will not be easily touched when
in operation.
Antenna Connections
Carefully follow the illustration regarding the proper connection of antennas and coaxial cables.
To prevent damage from lightning, atmospheric electrical discharges,
electric shock etc., provide a good earth ground.
Use a short, thick, braided cable to connect the station equipment to the
buried ground rod (or alternative earth ground system).
Power Cable Connections
Carefully follow the illustrations regarding the proper connection of the DC power cable.
Use the DC power cable supplied with the FT-710 to make the power connections to the power supply.

Installation guidelines
• Ensure adequate ventilation around the trans-
ceiver, to prevent heat build-up and possible re-
duction of performance due over heating.
• Do not install the transceiver in a mechanically
unstable location, or where objects may fall onto
it from above.
• To minimize the possibility of interference to
home entertainment devices, take all precaution-
ary steps including separation of TV/FM anten-
nas from Amateur transmitting antennas to the
greatest extent possible. Keep the transmitting
coaxial cables separated from cables connected
to home entertainment devices.
• The AC Power Cord connected to a socket-out-
let with earthing connection. A socket-outlet with
earthing connection shall connect to protective
earthing conductor.

CENTER : The receive frequency is always shown at the center of the screen and spectrum display.
The band spectrum is shown within the range set by “SPAN”.
The CENTER mode is convenient for monitoring the signal activity around the operating
frequency.
CURSOR : Monitors the spectrum within the range set with “SPAN”. When the frequency (marker)
exceeds the upper limit or the lower limit of the range, the screen is automatically scrolled
and the status beyond the setting range can be observed.

• ATT (Attenuator)
Displays the current ATT (Amount of receive input
signal attenuation).
When the desired signal is extremely strong or
the noise level is high on a low frequency band,
activate the attenuator to reduce the incoming
signal or noise from the antenna.
After touching [ATT], touch the desired attenua-
tion amount.
The attenuator is set independently for each op-
eration band.
OFF Attenuator is O󰀨
6dB The incoming signal power is reduced by 6dB
(Signal voltage reduced to 1/2)
12dB The incoming signal power is reduced by 12dB
(Signal voltage reduced to 1/4)
18dB The incoming signal power is reduced by 18dB
(Signal voltage reduced to 1/8)
• IPO
The IPO (Intercept Point Optimization) function
can establish the gain of the RF amplier section
to accommodate the connected antenna and the
received signal conditions. IPO can be selected
from three operating conditions.
AMP1: One stage RF amplifier is connected.
This is a well-balanced operation of re-
ceiver sensitivity and characteristics (Ap-
proximately 10 dB gain).
AMP2: Two RF amplifiers are connected in se-
ries to give top priority to sensitivity (Ap-
proximately 20 dB gain).
IPO: The received signal is input to the IF mix-
er without passing through the RF ampli-
fier. This can greatly improve receiving,
especially in the harsh low band signal
environment.
After touching [IPO], touch the desired operating
condition.
• IPO is set independently for each operation
band.
• Normally, select “AMP1”.
• The IPO can not only attenuate the input sig-
nal but also improve the intermodulation char-
acteristics. It is most e󰀨ective to operate the
IPO rst, and then use the ATT if the signal is
still too strong. The noise level can be attenu-
ated and S/N greatly improved.
• DNF (Digital NOTCH Filter)
The Digital NOTCH Filter (DNF) is an effective
beat-canceling filter that can null out a number
of interfering beat notes inside the receiver pass-
band.
Because this is an Auto-Notch feature, there is no
djustment knob associated with this lter.
• AGC (Automatic Gain Control)
Displays the currently selected AGC setting.
The AGC system is designed to help compen-
sate for fading and other propagation e󰀨ects. The
AGC characteristics can be individually set for
each operating mode. The basic objective of AGC
is to maintain a constant audio output level once
a certain minimum threshold of signal strength is
achieved.
After touching [AGC], touch the desired time con-
stant.
● AGC can be set for each operation band.
● The “AUTO” selection mode selects the opti-
mum receiver-recovery time for the reception
mode.
Operating Mode AUTO AGC Selection
LSB / USB / AM / AM-N SLOW
CW-L / CW-U / FM / FM-N
DATA-FM / D-FM-N FAST
RTTY-L / RTTY-U
DATA-L / DATA-U / PSK MID
Normally, AGC is set to “AUTO”, which auto-
matically selects the time constant according to
the received signal type, but when receiving a
weak signal or when there is noise and fading,
the AGC action may be changed according to
the reception condition at that time. Change the
time constant to make received signals most
audible
Several aspects of AGC performance may be
configured via the Menu. However, because
AGC can have such a profound impact on over-
all receiver performance, we generally do not
recommend any changes to the AGC Menu se-
lections until you are thoroughly familiar with the
performance of the FT-710.
Important Receiver Settings
The status of various operations that are important during receive, are shown at the bottom of the display.
To change a setting, touch the appropriate location on the display.

Scope Display Setting
In addition to the conventional two-dimensional waterfall spectrum display, Yaesu has added the 3-Dimen-
sion Spectrum Stream (3DSS) color display. The constantly changing band conditions and signals are
depicted in real time and color. The frequency span is shown on the horizontal X axis, the vertical Y axis
depicts the signals and their strengths, and the time is represented on the receding Z axis. The FT-710
operator can intuitively grasp the band and signal conditions at any instant.
• CENTER/CURSOR/FIX
Switches the Spectrum Scope operation each time the key is touched.
• When the display area is touched, the receive frequency is moved to that point.
• In CENTER mode, the frequency touched becomes the center.
• In CURSOR and FIX mode, the marker and the receive frequency move to the touched position.
• CENTER
The receive frequency is always shown at the center
of the screen and spectrum display. The band spec-
trum is shown within the range set by “SPAN”. The
CENTER mode is convenient for monitoring the sig-
nal activity around the operating frequency.
