User manual YAESU FTDX5000D HF PRODUCT REVIEW 12-2010

[. . . ] PRODUCT REVIEW Yaesu FTDX5000D HF and 6 Meter Transceiver Reviewed by Rick Lindquist, WW3DE Managing Editor, National Contest Journal Yaesu's latest colossus rules, delivering top tier performance at a substantially less than a top tier price. The FTDX5000 series establishes a new benchmark, the highest close-in IMD dynamic range and third-order intercept we've ever measured. It can and will do the heavy lifting for the most demanding DXer or contester. Over the past several years, Yaesu has deployed an array of such signature signal enhancing features as Contour, VRF, µ-Tune and Class A. [. . . ] This represents excellent real-world performance, which holds up right through 6 meters!For Receiver B, with a VHF IF and without the narrow roofing filters, the worst-case dynamic range was 88 dB on 14 MHz at 2 kHz spacing; all other numbers were in the 90s, the best being 98 dB on 14 MHz at 5 kHz spacing, yielding an IP3 of +25 dBm.

The 144 page Operating Manual has a lot of information about setting up and using the many features this radio offers, but it could use some improvement. Among other things it lacks a CAT reference as well as a detailed index, although Yaesu does provide supplementary information on its Web site. I detected a low level hum or tone when turning the VFO A AF GAIN control past about 12 o'clock. [. . . ]
