400 MHz built-in IF DSP. Fast and robust IF DSP processing! 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! 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. Whats 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. FM - 2.5/5.0. CW - 0.5/1.8/2.4 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 interference. The total passband tuning range for the IF Shift system is ±1 kHz.
Rotate the [SHIFT] knob to the left or right to reduce the interference. You may observe the position of the passband in the SHIFT indicator of the DSP Graphic Display portion of the LCD front panel main display.
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. The DSP Contour filter is a unique capability of the receiver, providing either Nulling or Peaking of tunable segments of the receiver passband to suppress interference or excessive frequency components on an incoming signal, or to peak those tunable frequency segments.
The amount of Nulling / Peaking and the bandwidth over which it is applied are adjustable via the Menu. The peak position of the contour filter is graphically depicted in the CONTOUR indicator of the DSP Graphic Display portion of the LCD front panel main display. SPECIAL FILTERING NOTE: The steep slopes of the DSP filtering can, when adjusted aggressively, impart an unnatural sound to an incoming signal. Often, a narrow bandwidth is not the key to improving copy. The incoming signal itself may have undesirable or excessive frequency components.
By judicious use of the Contour filter, the shoulder of the passband response may be altered, or components removed from within the passband, allowing the desired signal to rise above the background noise and interference in a manner not obtainable with other filtering systems. 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. You may observe the graphically depicted peak position of the IF Notch filter in the NOTCH indicator of the DSP Graphic Display portion of the LCD front panel main display. 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. You get to choose the selection that provides the best noise suppression.The DSPs 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. Any of eleven different noise-reduction algorithms can be selected. Each of these algorithms was created for dealing with a different noise profile. You will want to experiment with the DNR system to find the best setting according to the noise currently being experienced that concurrently will allow the signal to rise up out of the noise.
The FT-450D Manual Notch Filter is a highly-effective system that slices out an interfering beat tone/signal. Lots of receiver frequency verstility provided by an easy to engage Clarifier. IPO/ 20 dB ATT Built-in. The 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. When in split frequency mode, depressing the TXW button lets you listen to the frequency you have selected for transmitting. Record and playback up to 20 seconds of audio! Custom set your rig to match your voice characteristics for maximum power punch on the band. The FT 450D comes packed with all the CW operating features one could ever ask for! Terrific CW selectivity provided by 300Hz, 500Hz, and 2.4kHz CW IF Filters. 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. The FT 450D Spotting feature will help you get right on frequency with the station you want to call. Load up the 3 memory channels with information you repeated have to send. The CW sidetone volume and tone are menu adjustable to fit your favorite settings. The FT 450D CW Beacon allows up to 118 characters using the CW mMssage Keyer's 3 memories.
Random Morse code is generated for code practice via the built-in sidetone generator. A jack located on the back panel provides control circuitry for your high power linear amplifier.
