First Look: Yaesu FT-710 HF Transceiver

Yaesu has introduced the new FT-710, a compact high-frequency (HF) plus 50 MHz transceiver that will slip into the entry-level spot vacated by the FT-991. Pumping out a maximum 100 watts of power, the Yaesu FT-710’s software-defined receiver (SDR) is actually the star of the show. The FT-710 is equipped with the same high-resolution analog-to-digital (A/D) converter and Field Programmable Gate Array (FPGA) used in the Yaesu’s higher-end transceivers. The twin A/D converter circuit configuration performs digital conversions, then the digital signal is combined by the FPGA to reduce overload and overflow of the A/D converters and improve blocking characteristics. Random noise is then added to the analog signal before digital conversion, which is suppressed by minimizing the quantification error during conversion by the A/D converter and a dithering technology…
