Yaesu FT-450D

Yaesu FT-450D Features

Yaesu 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.

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

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

Yaesu 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!

IF Shift & Width

The FT-450D IF Width and IF Shift features are the primary tools you will use for best interference reduction. The IF WIDTH tuning system allows you to vary the width of the DSP IF passband to eliminate interference. 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.

Contour

The Contour filtering system provides a gentle shaping of the IF filter pass band to suppress or enhance particular frequency components, thus improving the sound and/or readability of a received signal.

IF Notch

The IF Notch filter is a highly effective system that allows you to slice out an interfering beat note or other carrier signal from inside the receiver passband.

DNR – Digital Noise Reduction

The Digital Noise Reduction (DNR) feature utilizes eleven (11) different mathematical algorithms to analyze and suppress different noise profiles encountered on the HF/50 MHz bands. The DSP’s Digital Noise Reduction (DNR) system is designed to reduce the level of random noise found on the HF and 50 MHz bands. It is especially effective during SSB operation.

Manual Notch Filter

The FT-450D Manual Notch Filter is a highly-effective system that slices out an interfering beat tone/signal

Clarifier

Lots of receiver frequency verstility provided by an easy to engage Clarifier

IPO/ 20 dB ATT Built-in

Yaesu FT-450D includes all the gain you will need all the way up to 50MHz. For lower HF bands where too much gain can lead to receiver issues, you can easily adjust the gain from the front panel.

TX Watch Monitor

When in split frequency mode, depressing the TXW button lets you listen to the frequency you have selected for transmitting.

Digital Voice Recorder

Record and playback up to 20 seconds of audio!

Digital Microphone Equalizer

Custom set your rig to match your voice characteristics for maximum power punch on the band.

  Terrific CW selectivity provided by 300Hz, 500Hz, and 2.4kHz CW IF Filters. Nothing to buy!

• Built-In Electronic Keyer

  The Built-In Electronic Keyer speed is adjustable from 4 to 60 WPM. You will also be able to select your favorite CW weight – Dot-Dash Ratio.

• Spotting (Zero-Beating)

  Yaesu FT-450D Spotting feature will help you get right on frequency with the station you want to call.

• Memory Keyer

  Load up the 3 memory channels with information you repeated have to send.

• Sidetone Generator

  The CW sidetone volume and tone are menu adjustable to fit your favorite settings.

• Beacon Function

  Yaesu FT-450D CW Beacon allows up to 118 characters using the CW mMssage Keyer’s 3 memories.

• CW Training Feature

  Random Morse code is generated for code practice via the built-in sidetone generator.

Linear Control

A jack located on the back panel provides control circuitry for your high power linear amplifier.

Built-in TCXO

Yaesu FT-450D includes a TCXO for incredible frequency stability!

Dedicated Data Jack for FSK-RTTY operation

The rear panel of Yaesu FT-450D has a jack dedicated to FSK-RTTY and digital mode operation!

CAT System (D-sub 9 pin): Computer programming

Yaesu FT-450D CAT System allows uploading of factory provided firmware updates as well as computer control of the radio.

Versatile Memory System

Up to 500 memory channels can be set and separated into as many as 12 Memory Groups.

My Band / My Mode Functions

Use Yaesu FT-450D My Band / My Mode functions to recall your favorite operating environments

Scan Function

Yaesu FT-450D includes a number of very useful and versitile Scan function settings.

CTCSS Operation (FM)

We did not forget to include CTCSS operator for 10 and 6 meter FM operation.
