General Description

SDR receiver circuit designed with emphasis on fundamental performance

The high-resolution A/D converter and the FPGA element developed for the high-end SDR Yaesu Transceivers are utilized. The twin A/D converter circuit configuration performs digital conversion processing using two A/D converters and FPGA digital synthesis. A/D converter overflow due to overload is reduced to improve blocking characteristics. In addition, random noise is added to the analog signal before digital conversion, and by minimizing the quantization error during digital conversion by the A/D converter, distortion is suppressed. Then Dithering technology is implemented to improve IM (intermodulation) characteristics, etc., and enhance the overall performance of the SDR receiver circuit.

3DSS method adopted

In addition to the conventional waterfall display, a 3DSS (3 Dimensions Spectrum Stream) image method has been adopted. The 3DSS image uses the horizontal axis (X axis) for frequency, the vertical axis (Y axis) for signal intensity, and the Z axis for time. Compared to the conventional waterfall method, the signal strength is displayed in three dimensions as well as in color, recognition of changes in the band conditions is instant, convenient and intuitive.

AESS (Acoustic Enhancement Speaker System) produces high-fidelityAudio

Using DSP signal processing, the speaker in the top of the Transceiver, and an external side speaker are combined to reproduce high-quality received audio with a wide frequency range and a three-dimension- al effect that would not be expected from a compact HF transceiver. set the optimum sound quality by adjusting the output balance and frequency characteristics of the two speakers according to your preference.

High-brightness TFT full-color display with touch-panel functionality

The FT-710 is equipped with a 4.3-inch full-color TFT display. Operating functions, including the receiving band noise and signal interference reduction tools, are graphically displayed. Even while involved in rigorous operations, such as DXpeditions and contests, the operator may instantly grasp the status of each function.

Filter Function Display monitors the status of the passband

In the upper part of the display, a filter function display presents the state of the pass-band. In addition to the operating state of the interference removal functions, the filter function information is displayed. Not only can you grasp the operating status of WIDTH, SHIFT, NOTCH and CONTOUR at a glance, you can also view the status of the RF spectrum in the passband.

Two selectable RF Stages amplify the desired signals from low band to high band

RF amplifier AMP1, and AMP2 are low noise negative feedback RF amplifiers that may be selected or combined in series as is needed for various low-band, high-band, frequency and noise conditions.

In addition, the IPO (Intercept Point Optimization) function maximizes the dynamic range and enhances the close multi-signal and inter-modulation characteristics of the receiver. The influence of strong broadcasting stations, especially in the low bands, can be minimized.

WIDTH and the continuously variable Bandwidth SHIFT features permit elimination of interfering signals

The WIDTH feature allows the bandwidth to be narrowed by rotating the WIDTH knob. The SHIFT feature, can eliminate interference in one side of the passband. Often, weak signals disappear due to interfering signals (including pile-ups). The interfering signals may be extracted, leaving only the desired signal, because of the unique DSP sharp filtering characteristics.

CONTOUR feature is renowned for effective noise reduction

Rather than using the DSP extremely sharp attenuation characteristics, the CONTOUR circuit provides gentle shaping of the DSP passband filter, and can thus attenuate or peak bandwidth components in segments. The interfering signal can be naturally shaped without having part of the signal suddenly disrupted.

The contour function is very effective in making the desired signal rise out of the interference.

4

DNR (Digital Noise Reduction) by DSP digital processing

The incorporated digital noise reduction circuit may be set to the optimal working algorithm by varying the 15 step parameters according to the noise type.

NOTCH feature can eliminate an unwanted heterodyne, and the DNF feature can instantly attenuate multiple heterodyne signals

When interfering beat signals are present in the receiver passband, the IF NOTCH feature can significantly eliminate a narrow portion of the passband and remove the interfering signal. Moreover, when there are multiple interfering signals, the DSP DNF (Digital Notch Filter) Automatic Tracking System can be effective, even when an interfering frequency is changing.

[FUNC] (function) knob

Simply press the function [FUNC] knob to easily select the setting menu, and then change the setting value. Quick response is possible even while operating. Assign a frequently used function or setting menu and then you can easily change the setting just by turning the knob.

VMI (VFO mode indicator)

The VMI is placed on the left and right sides of the MAIN dial to show the current operating status of

VFO-A, VFO-B, Memory mode and clarifier/split operation.

The color of the VMI indicator may be selected from 4 colors (blue/green/red/white) for each operation status.

SD memory card

An SD card slot on the left side of the front panel permits using a commercially available SD memory card for recording/playback of received audio, for voice recording for transmission, to save the various operating settings, saving memory contents, and screen capture (saving the display screen). The SD card is also used to update the firmware.

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.

Check the DC voltage and current rating

(+13.8 V, 25 A) of the power supply before connecting to the transceiver.

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.

Important setting items when receiving

• 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 attenuation amount.

The attenuator is set independently for each operation band.

	OFF	Attenuator is Off
	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 amplifier 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 receiver sensitivity and characteristics (Approximately 10 dB gain).

AMP2: Two RF amplifiers are connected in series to give top priority to sensitivity (Approximately 20 dB gain).

IPO: The received signal is input to the IF mixer without passing through the RF amplifier. 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 signal but also improve the intermodulation characteristics. It is most effective to operate the IPO first, and then use the ATT if the signal is still too strong. The noise level can be attenuated 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 passband.

Because this is an Auto-Notch feature, there is no djustment knob associated with this filter.

• AGC (Automatic Gain Control)

Displays the currently selected AGC setting.

The AGC system is designed to help compensate for fading and other propagation effects. 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 constant.

●AGC can be set for each operation band.

●The “AUTO” selection mode selects the optimum 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	FAST
	DATA-FM / D-FM-N
	RTTY-L / RTTY-U	MID
	DATA-L / DATA-U / PSK

Normally, AGC is set to “AUTO”, which automatically 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 overall receiver performance, we generally do not recommend any changes to the AGC Menu selections until you are thoroughly familiar with the performance of the FT-710.

About TFT Displays

FT-710 utilizes a TFT liquid-crystal display.

Although TFT liquid-crystal displays are made using very precise technology, they are prone to develop dead pixels (dark dot) or pixels that are always on (bright dot). Please understand that such phenomena do not constitute product defects or malfunctions. Rather, this phenomenon occurs due to limitations in the manufacturing technology with respect to TFT liquid-crystal displays.

•Depending on the viewing angle, unevenness in color or brightness may occur. Please note that any unevenness observed is inherent to the construction of TFT liquid crystal displays and therefore does not constitute a product defect or malfunction.

•If your TFT liquid-crystal display becomes dirty, please use a dry soft cloth or tissue to wipe the display clean. If it is extremely dirty, moisten it with water or lukewarm water and wipe it off with a soft cloth that has been wrung out tightly. Use of glass cleaner, household cleaners, organic solvents, alcohol, abrasives, and/or like substance may damage the TFT liquid-crystal display.
