Yaesu FT-710 AESS HF/50MHz 100W SDR

The Yaesu FT-710 AESS is a compact HF/50MHz SDR transceiver equipped with the same high-resolution A/D converter and FPGA used in Yaesu's high-end SDR transceivers. The dual A/D converter circuit configuration performs digital conversion processing using two A/D converters. The digital signal is combined by the FPGA to reduce overload and overflow of the A/D converters and improve blocking characteristics. Additionally, random noise is added to the analog signal before digital conversion, distortion is suppressed by minimizing quantization error during digital conversion by the A/D converter, and dithering technology is used to improve IM (Intermodulation) characteristics. The overall performance of the SDR receiving circuit is excellent.

The Yaesu FT-710 AESS comes standard with the Yaesu SP-40, a speaker with a frequency response of 250-20000Hz and an impedance of 4 Ohm. This SDR circuit configuration thus emphasizes reception performance.

Acoustic Enhancement Speaker System - AESS

The Acoustic Enhancement Speaker System is generated by digital processing. The Mid-Low-frequency enhancement speaker and the side speaker are combined to create a dramatic overall audio frequency response and hi-fi audio output.

Quick Memory Bank function - QMB

The QMB function can be used to store special memory channels. With a single button press, a memory can be easily recalled. The Quick Memory Bank stores the frequency, mode, and also the transmit/receive settings, filter, and other parameters, allowing operation to start quickly and in optimal condition without resetting when switching bands. Memory settings can be easily checked by displaying the memory contents on the screen. (A maximum of 10 memory channels are available).

The front panel design emphasizes the operational efficiency and comfort of this compact transceiver with a large 4.3-inch TFT color touch screen, offering intuitive operation and excellent visibility. Primary control functions are arranged on the front and centered above the VFO dial for operational efficiency and direct access.

• Scope: The Scope function provides a real-time spectrum display of band conditions.
• Intercept Point Optimization (IPO): the IPO function can determine the gain of the RF amplifier section to accommodate the connected antenna and received signal conditions
• IF Noise Blanker (NB): the FT-710 includes an effective IF Noise Blanker, which can significantly reduce noise caused by car ignition systems
• IF SHIFT operation: IF Shift allows the passband of the digital filter to be shifted higher or lower without changing the pitch of the incoming signal
• Automatic Gain Control (AGC): the AGC system is designed to help compensate for fading and other propagation effects
• Digital NOTCH Filter (DNF): the Digital NOTCH Filter (DNF) is an effective beat-cancelling filter that can eliminate a number of interfering beat notes in the receiver's passband
• IF NOTCH filter (NOTCH): the IF NOTCH filter is a very effective system that allows you to remove an interfering beat note or another carrier signal from the receiver's passband
• AF / RF gain / Squelch
• Automatic antenna tuner (ATU): the automatic antenna tuner is built into every FT-710. The ATU is designed to ensure that an antenna impedance load of 50 Ω is presented to the final amplifier stage of the transmitter
• Parametric microphone equalizer: the FT-710 includes a unique three-band parametric microphone equalizer that provides precise, independent control over the low, mid, and high tones in the voice waveform.
• Time-Out Timer (TOT): the "Time-Out Timer" (TOT) switches the transmitter OFF after continuous transmission for the programmed time
• Bandstack: the Yaesu FT-710 uses a triple-band-stack VFO selection technique that allows up to three favorite frequencies and modes to be stored in each VFO band register.
