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-fidelity Audio
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-dimensional 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 6dB 12dB 18dB

Attenuator is Off
The incoming signal power is reduced by 6dB (Signal voltage reduced to 1/2)
The incoming signal power is reduced by 12dB (Signal voltage reduced to 1/4)
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 sig-
nal 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 opti-
mum receiver-recovery time for the reception mode.

Operating Mode LSB / USB / AM / AM-N
CW-L / CW-U / FM / FM-N DATA-FM / D-FM-N
RTTY-L / RTTY-U DATA-L / DATA-U / PSK

AUTO AGC Selection SLOW FAST
MID

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.

Because the tuned carrier frequency is not varied, there is no need to re-tune the operating frequency to eliminate the interference. The total passband tuning range for the IF SHIFT system is ±1.2kHz.
2. WIDTH
The IF WIDTH tuning system allows you to vary the width of the DSP IF passband, to reduce or eliminate interference. Moreover, the bandwidth may actually be expanded from its default setting, should you wish to enhance incoming signal fidelity when interference on the band is low.
3. NOTCH
The IF NOTCH filter is a highly effective system that allows removing an interfering beat note or other carrier signal from within the receiver passband.
4. CONTOUR
The Contour filter system provides a gentle perturbation of the IF filter passband. The Contour is set to either suppress, or boost specific frequency components, and thus enhances the sound and readability of a received signal
5. APF
During CW operation, when interference or noise is present, the center frequency is automatically set to the PITCH frequency, making it easier to hear the desired signal

Voice Communications (SSB and AM)
When transmitting in SSB or AM mode
The FT-710 transmit audio circuit can be set to the optimum operating level by individually adjusting the input and output gains of the microphone amplifier.

The AMC (Automatic Microphone Gain Control) regulates the microphone audio so that distortion does not occur, even if excessive audio is input.

1. Adjust Microphone gain
Touch the Meter Display and then touch “ALC” to select the ALC Meter. 1. Press the [FUNC] knob. 2. Touch [MIC GAIN]. 3. Key TX and adjust the [FUNC] knob to set the
input level of the Microphone Amplifier to the position where the ALC Meter needle does not exceed the ALC zone on the audio peaks.

2. Adjust the AMC gain
Touch the Meter Display and then touch “COMP” to select the COMP Meter. 1. Press the [FUNC] knob. 2. Touch [AMC LEVEL]. 3. Activate the transmit and speak into the mi-
crophone while adjusting the AMC level with the [FUNC] knob. Adjust the AMC to a point where the COMP Meter deflection does not exceed “10dB” on the audio peaks.
Setup is completed.

The AMC function only works in LSB, USB, AM, AM-N, DATA-L, DATA-U and PSK modes. It does not work in other modes.

Set with the FUNC knob
Operate the [FUNC] knob to make the following settings.
PROC LEVEL: Adjust the level of the speech processor function. RF POWER: Adjust the transmit power. MONI LEVEL: Adjust the monitor level.

FUNC knob
The last function used is retained in the [FUNC] knob so it can be easily set by operating the [FUNC] knob. Normally, it is suggested to utilize the [FUNC] knob as the [LEVEL] knob for the spectrum scope.
40

Speech Processor
The FT-710 Speech Processor is designed to increase “talk power” by increasing the average power output of the transmitted SSB signal.
The speech processor function only works in LSB/USB mode. It does not work in other modes. 1. Adjust the MIC gain as described on the previous page. 2. Press the [FUNC] knob. 3. Touch [PROC LEVEL].
4. Touch the Meter area on the display to select the “COMP” meter. The transmit meter becomes the “COMP” meter.
5. Press the PTT switch on the microphone, and speak into the microphone in a normal voice level.
6. Adjust the [FUNC] knob to set the compression level within 10 dB. The Transmit Monitor is a helpful aid to verify proper adjustment of the Compression level. The “PROC” indicator lights in the display.
Rotate the [FUNC] knob to the left to turn the speech processor function “OFF”.
The speech processor can distort the transmit waveform when used to increase the average TX power, so it is not used in normal communication.
RF Power output control
Turn the [FUNC] knob to adjust the RF power output. 1. Press the [FUNC] knob. 2. Touch [RF POWER].
3. Rotate the [FUNC] knob to adjust the RF power. When transmitting in the AM mode, set a maximum (carrier) power output of 25 Watts.

Setting of maximum transmission output The maximum transmit power can be set for each of the HF Bands, the 50MHz band and the AM mode. Set it according to operating conditions, when high transmit power is not needed. 1. Press the [FUNC] knob. 2. Select [OPERATION SETTING] [TX GEN-
ERAL]. 3. Rotate the [FUNC] knob to select the item
you want to set. HF MAX POWER (HF band) (The setting range is 5 to 100 W) 50M MAX POWER (50 MHz band) (The setting range is 5 to 100 W) 70M MAX POWER (70 MHz band) (The setting range is 5 to 50 W) AM MAX POWER (AM mode) (The setting range is 5 to 25 W) 4. Press the [FUNC] knob, or wait for about 3 seconds to save the setting. 5. Touch [BACK] several times to return to normal operation.
MONI (Monitor)
Use the Monitor feature to listen to the quality of the transmitted signal. 1. Press the [FUNC] knob. 2. Touch [MONI LEVEL].
3. Rotate the [FUNC] knob to adjust the Monitor level.
Transmit audio monitor is not activate in the FM, FM-N, DATA-FM and D-FM-N modes.
If you are using the speaker for monitoring, instead of headphones, excessive advancement of the Monitor level can cause feedback to occur. Additionally, this feedback can cause the VOX system to hang up in a loop, making it impossible to return to receive. Therefore, we recommend the use of headphones, if at all possible, or the minimum usable setting of the Monitor level, if the speaker must be used.
4. To cancel the monitor function, turn the [FUNC] knob to set “MONI LEVEL” to “OFF”.
Because the Monitor feature samples the transmitter IF signal, it can be very useful for checking the adjustment of the Speech Processor or Parametric Equalizer on SSB, and for checking the general signal quality on AM.
41

Parametric Microphone Equalizer
The FT-710 includes a unique Three-Band Parametric Microphone Equalizer that provides precise, in- dependent control over the low, mid and treble ranges in the voice waveform. One group of settings may be utilized when the Speech Processor is Off, and an alternate group of settings when the Speech Processor is On (SSB mode only). The speech processor feature is described in the next chapter.
Parametric microphone equalizer function is activated only in LSB, USB, AM, AM-N, FM and FM-N modes.

· Setup the Parametric Microphone Equalizer
1. Set the RF output power to minimum value.
We recommend connecting a dummy load to one of the Antenna jacks, and monitoring the signal on a separate receiver, to prevent interference to other users.
2. Press the [FUNC] knob. 3. Touch [MIC EQ].
Parametric Microphone Equalizer function is activated. To adjust the Parametric Microphone Equal-
izer with the Speech Processor engaged, activated the Speech Processor. 4. Press the [FUNC] knob. 5. Touch [MONI LEVEL]. 6. Rotate the [FUNC] knob to adjust the Monitor level. 7. Press the [FUNC] knob. 8. Select [OPERATION SETTING][TX AUDIO]. 9. Rotate the [FUNC] knob to find Menu items [PRMTRC EQ1 FREQ] through [PRMTRC EQ3 BWTH]; these parameters apply to the adjustment of the Parametric Microphone Equalizer when the Speech Processor is disabled. Menu items [P PRMTRC EQ1 FREQ] through [P PRMTRC EQ3 BWTH] apply to the adjustment of the Parametric Microphone Equalizer when the Speech Processor is engaged. 10. Rotate the [FUNC] knob, or touch “<” or “>” on either side of the value to adjust a particular Menu item. 11. Press and hold the PTT switch, and speak into the microphone while listening to the effect of the adjustments being made. Because the overall sound will change with each adjustment, make several passes through each adjustment area, to be sure that the optimum

settings are achieved. The best way to hear the effects of the ad-
justments is to wear headphones (connected to the monitor receiver) while listening to the transmitted signal. 12. When all adjustments are satisfactory, press the [FUNC] knob, or wait for about 3 seconds to save the setting. 13. Touch [BACK] several times to return to normal operation.

Using the Automatic Antenna Tuner
The Automatic Antenna Tuner (ATU) is built into each FT-710. The ATU is designed to ensure that a 50Ohm antenna impedance load is presented to the final amplifier stage of the transmitter.
· Because the FT-710 ATU is located inside transceiver, it can only adjust the impedance presented to the transceiver end of the coaxial cable feedline. It does not “tune” the SWR at the antenna feed point itself. When designing and building an antenna system, we recommend that every effort be made to also ensure a low SWR at the antenna feed point.
· The ATU in the FT-710 is designed to match impedances within the range of 16.5 Ohms to 150 Ohms, corresponding to an SWR of 3:1 or less on the HF amateur bands (6 m amateur band: 25 Ohms to 100 Ohms, corresponding to an SWR of 2:1 or less). Accordingly, simple non-resonant whip antennas, along with random-length wires and the “G5RV” antenna (on most bands) may not be within the impedance matching range of the ATU.
· The built-in antenna tuner cannot be used with an antenna connector connected to an external antenna tuner.

· ATU Operation
1. Press the [TUNE] key momentarily to place the ATU in the transmit line (no adjustment or tuning will occur yet). While the ATU function is activated, the “TUNE” will be displayed.
The momentary press of the [TUNE] key will turn the tuner ON, and the microprocessor will automatically select the tuning point closest to the current operating frequency.
2. Press and hold the [TUNE] key to begin automatic tuning. The transmitter will be engaged, and “TUNE” will be displayed while tuning is in progress. Always listen on the operating frequency before beginning the tuning process, to be sure tuning will not interfere with others who may already be using the frequency. When the optimum tuning point has been achieved, the transceiver will return to receive.
3. To disengage the ATU from the transmit line, press the [TUNE] key momentarily.
The ATU microprocessor memories store the record of the capacitors and inductors selected to tune each 10kHz window in which tuning has occurred. This eliminates the need to retune every time operation returns to a frequency on which the tuning process has already been completed.

About ATU Memories SWR (After tuning) Less than 2:1 The tuner settings are stored in the ATU memory.
SWR (After tuning) Greater than 2:1 Tuning data will not be retained in memory. If operation is returned to the same frequency, the tuning process must be repeated.
SWR (After tuning) Greater than 3:1 The “HI-SWR” icon will light up, and the tuner settings, if achieved, will not be memorized. Investigate the high SWR condition and resolve the problem before attempting further operation using this antenna.

48

CW Mode Operation

The impressive CW operating capabilities of the FT-710 permit operating with an Electronic Keyer Paddle, a “Straight Key”, or a computer based keying device.
1. Before starting, connect the key cable to the rear panel KEY jack.
2. Set the operating mode to CW-U. The normal “CW” mode utilizes USB-side carrier injection.
3. Rotate the Main Tuning Dial knob to select the desired operating frequency.
4. Press the [FUNC] knob.

· CW Delay Time Setting
During semi-break-in (not QSK) operation, the hang time of TX, after the transmitting ends may be adjusted to a comfortable value corresponding with the sending speed.
1. Press the [FUNC] knob, then touch [BK-DELAY]. 2. Start sending and rotate the [FUNC] knob to
adjust the hang time for comfortable operation. 3. Approximately 1 second after selection, the settings are saved and the normal operation screen returns.
CW Spotting (Zero-Beating)
“Spotting” (zeroing in on another CW station) is a handy technique to ensure the transceiver and the other station are operating precisely on the same frequency.
The Tuning Offset Indicator in the display may also be moved to adjust the receiver frequency to center on the incoming station with the CW pitch corresponding to that of the transmit signal.

5. Touch [BK-IN] to turn ON the BK-IN function. 6. Touch [MONI LEVEL] and then turn the
[FUNC] knob to adjust the volume of the monitor. 7. When using the keyer paddle, press the [FUNC] knob and then touch [KEYER] to turn ON the Electronic Keyer. 8. When the key or the keyer paddle is pressed, the transmitter will automatically be engaged.
Press [FUNC], then touch [CW SPEED], and rotate the [FUNC] knob to set the desired sending speed.
As shipped from the factory, the FT-710 CW TX/RX is configured for “Semibreak- in” operation. However, using Menu item “CW BK-IN TYPE”, this setup may be changed to full break-in (QSK) operation, wherein the switching is quick enough to hear incoming signals in the spaces between the dots and dashes of the transmission. This may prove very useful during contest and traffic handling operations.
· Adjusting the Sidetone Audio level
The CW sidetone audio level may be adjusted by press the [FUNC] knob, then touch [MONI LEVEL], and then rotating the [FUNC] knob.

Turn OFF the Tuning Offset Indicator using Menu item “CW INDICATOR”.
