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. This radio shares DNA with earlier Yaesu offerings.

Equivalent keying speed is 60 WPM using external keying. Spectrum analyzer resolution bandwidth is 10 Hz, and the sweep time is 30 seconds. The transmitter was being operated at 200 W PEP output on the 14 MHz band, and this plot shows the transmitter output ±5 kHz from the carrier.

[. . . ] The IF notch can be set to narrow or wide via the menu. The DNF (digital notch filter) is automatic and fixed. Everyone's radio should have the FTDX5000's CW tuning guide, especially those folks who persist in calling you 300 Hz off frequency when you're running a tight filter. You can repurpose the CW tuning guide to serve as a CLAR (clarifier or RIT) offset bar. [. . . ]
