Audio input and output are directed to the USB AUDIO CODEC, with a recommended WSJT-X Pwr Slider setting of -32.0 dB, adjusted to ensure ALC meter readings remain within the white segment on the FTDX10. Transceiver-specific settings include a CAT RATE of 38400 bps, AMC RELEASE TIME set to MID, and DATA SHIFT (SSB) at 1500 Hz. The RPORT GAIN is specified at 70, with notes suggesting lower values (e.g., 30) can also yield clean signals. Transmit bandwidth selection is discussed, recommending 50-3050Hz for wideband modes like MSK144, while suggesting 400-2600Hz for FT4/FT8 to mitigate second harmonics and improve signal purity. The guide also references discussions with W5AJ, DO1YHD, AC6BW, and W9RTB.

Evaluates the Yaesu FTDX10 receiver performance against an Elecraft K3 (serial #216) during the NAQP CW contest, specifically assessing weak signal reception adjacent to strong signals. Testing involved a 300 Hz bandwidth, Audio Peak Filter (APF) activation, 6 dB attenuation, and preamplifier deactivation to simulate challenging operating environments. The FTDX10's adjustable APF, offering NARR, MED, and WIDE settings, is directly compared to the K3's single APF setting. Observations highlight the FTDX10's superior suppression of a strong signal at X+100Hz, demonstrating less bleed-through into the passband compared to the K3, even with the K3's 500Hz roofing filter engaged. This indicates improved dynamic range and selectivity in the FTDX10's receiver architecture under high-intensity signal conditions. The analysis also briefly notes transmit T/R relay noise characteristics, providing a comprehensive, albeit concise, technical comparison of these two popular HF transceivers.

The Yaesu FTDX10 MF/HF and 6-meter transceiver, a 100-watt rig, is designed to bring high-performance receiver architecture to the intermediate-price class. It offers continuous receive coverage from 30 kHz to 75 MHz and transmit capabilities across all amateur bands from 160 through 6 meters, including five preset CW and SSB channels on 60 meters. The transceiver supports AM, FM, SSB, CW, and digital modes, with integrated decoders for CW, RTTY, and PSK31, making it a versatile station for various operating preferences. Physically, the FTDX10 measures 3½ × 10½ × 10½ inches and weighs 13 pounds, requiring a 20–25 A DC power supply for full 100 W output. Its front panel features a 5-inch TFT color touchscreen and a large VFO knob, complemented by an SD memory card slot for recording audio and saving settings. Rear panel connectivity includes a single SO-239 antenna port, multiple USB ports for CAT control and peripherals, and DIN jacks for external digital mode hardware and linear amplifiers, though it lacks a dedicated low-noise receive antenna provision. ARRL Lab tests confirm excellent receiver performance, with blocking dynamic range exceeding 137 dB at 2 kHz spacing and robust IMD dynamic range figures. The hybrid receiver design incorporates selectable roofing filters at 500 Hz, 3 kHz, and 12 kHz, along with two preamplifiers and various attenuation levels, allowing operators to tailor reception characteristics to challenging band conditions. Transmitter performance is also rated very good, with low transmit phase noise.
