| Compact Size & Lightweight The FT-450D comes - complete with an Automatic Antenna Tuner - is a compact 9”W x 3.3”H x 8.5”D (w/o knobs) weighing only 8.8 pounds. This lightweight package is designed to be used as a desktop radio at home or in portable applications. The FT-450D can also be used mobile with the MMB-90 convenient mobile bracket accessory. Besides home or mobile operation, this easy to pack radio is a DXpeditioner or Emergency Service Provider dream come true - compact, lightweight, high performance receiver, and 100 watts output on 160 through 6 meters Amateur Radio bands. 100 Watts RF Ouput 160 - 6 Meters Enjoy a cool 100 watts RF output on all HF bands 160-10 meters plus the 6 meter band. The rugged FT 450D aluminum die-cast chassis with its quiet, thermostatically controlled cooling fan provides a solid foundation for the power amplifier during long hours of field or home use...including the challenges of contesting. Power Requirements The FT-450D can be powered by any convenient 13.8 VDC 22 amp external power source. Large Easy-to-Read LCD Display You will love the FT-450D 9-segment Black-Nega type LCD frequency display with Larger-Than-Normal easy to read characters. Illuminated Key Buttons Ease of operation enhanced through the use of easy-to-find illuminated front panel buttons. Classically Designed Main Dial & Knobs The FT 450D is equipped with classically designed Main Dial and Knobs giving it the desirable "Big Radio" feel. 400 MHz built-in IF DSP Fast and robust IF DSP processing! IF Roofing Filter The FT-450D includes a 10 kHz bandwidth Roofing Filter in the 67.899 MHz 1st IF, right after the 1st Mixer. This filter provides narrow-band selectivity to protect the following IF and DSP stages – a feature rarely found in rigs in this price range! IF Shift & Width The FT-450D IF Width and IF Shift features are the primary tools you will use for best interference reduction.
After narrowing the bandwidth (Width) and/or adjusting the center of the passband (Shift), the Contour control (see details of this feature below) may also yield additional signal-enhancement benefits on the net residual bandwidth. What’s more, the IF Notch Filter (see details of this feature below) may also be utilized in conjunction with the three other filter systems to significant advantage.
The IF WIDTH tuning system allows you to vary the width of the DSP IF passband to eliminate interference. Moreover, the bandwidth may actually be expanded from its default setting, should you wish to enhance incoming signal fidelity when interference on the band is low. The IF WIDTH is varied in steps: SSB - 1.8/2.4/3.0 kHz. AM - 3.0/6.0/9.0 kHz. FM - 2.5/5.0. CW - 0.5/1.8/2.4 kHz. kHz.
The IF SHIFT tuning system allows you to vary the DSP filter passband higher or lower, without changing the pitch of the incoming Signal to reduce or eliminate interference. Because the carrier tuning frequency is not varied, there is no need to re-tune the operating frequency when eliminating the inter |
