Evaluating a new HF transceiver, AA4OO shares his initial operational impressions of the Yaesu FT-DX10, contrasting its physical design and performance against his prior experiences with the Elecraft KX3 and Ten-Tec Eagle. He notes the FT-DX10's superior fit and finish but finds the front panel controls, particularly the AF/RF knob, to be cramped, leading to accidental VFO shifts. The review details the radio's audio characteristics, describing acceptable SSB performance but "muddy" CW audio at 450Hz, which he attributes to cabinet acoustics, necessitating an external speaker for clearer CW reception. The author also discusses the effectiveness of the FT-DX10's Digital Noise Reduction (DNR) for CW, finding it significantly better than the NR on the Eagle or KX3. He appreciates the MPVD (Multi-Purpose-VFO-Outer-Dial) for reducing menu reliance during QSOs, a feature he finds more intuitive than the dual-use buttons on his Ten-Tec Eagle. However, he expresses disappointment with the noisy T/R relay during full QSK operation and a loud internal fan, which detracts from his preference for a quiet operating environment. Further observations include the 800x640 resolution of the external display connector, which he considers outdated, and the CW decode function, which he finds less practical than the KX3's due to its display of "paragraphs" of text rather than a quick assist. Despite these "nits," the review provides a balanced perspective on the FT-DX10's strengths and weaknesses from a seasoned CW operator's viewpoint, concluding that it's a "mixed bag" compared to his other rigs.
