Large Easy-to-Read LCD Display You will love the FT-450 9-segment Black-Nega type LCD frequency display with larger-than-normal easy to read characters. 400 MHz built-in IF DSP Feature description will follow soon IF Roofing Filter The FT-450 includes a 10 kHz bandwidth Roofing Filter in the 68 MHz first IF, right after the first 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-450 IF Width and IF Shift features are the primary tools you should 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 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. 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. 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. 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. 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 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. 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.

| Model | | | | | | | Antenna Tuners | | | | ATU-450 | The ATU-450 Automatic Antenna Tuner responds to control commands from the FT-450 Transceiver, providing microprocessor-based impedance matching on the 160 through 6 meter amateur bands. The impedance matching range is from 16.5 ohms to 150 ohms (up to 3:1 SWR). Accordingly, the ATU-450 should not be expected to match “Long wire” type antennas unless you have taken specific design steps to ensure that the impedance presented to the FT-450 is within this specification. | | | | | FC-40 |
The FC-40 is a new, wide-range Antenna Coupler for the FT-450, FT-857, and FT-897 Series of Transceivers.
The FC-40 is a microprocessor-controlled antenna impedance matching network designed for use with all versions (original and “D”) of the FT-450, FT-857, and FT-897 HF/VHF/UHF Transceivers. The FC-40 makes use of control circuitry inside the transceiver, allowing the operator to monitor and control operation of the FC-40, which mounts near the antenna feedpoint. Fully waterproof, the FC-40 may be mounted outdoors in exposed locations, and will handle a 100 Watts of transmitter power.
The FC-40 is designed for operation on 7 ~ 54 MHz, when using an 8’ whip like the YAESU YA-007, or on 1.8 ~ 54 MHz when used with a random-length wire longer than 66’. Matching time is typically five seconds or less, and the required drive power is 4 ~ 60 Watts. The FC-40 sports a whopping 200 match-setting-point memories, for instant recall of the tuning settings. | | | | | Antennas | | | | ATAS-120 | Active-Tuning Antenna System | | | | | ATAS-25 | The ATAS-25 is a manually-tuned portable antenna system ideal for the FT-817, FT-897, and FT-857 transceivers. Capable of operating on the Amateur bands between 7 MHz and 450 MHz, the ATAS-25 is designed for mounting on a standard 1/4" camera tripod stud (tripod not supplied), and includes an innovative fine-tuning system allowing precise SWR adjustment in the field. | | | | | ATBK-100 | Balcony Mount Counterpoise Kit (Base Mount Required) | | | | | Brackets | | | | MMB-90 | Mobile Mounting Bracket for FT-450 | | | | | Cables | | | | CT-39 | Packet Cable | | | | | Headsets | | | | YH-77STA | Lightweight Stereo Headset for use with HF transcievers | | | | | Microphones | | | | MD-100A8X | Desktop Microphone | | | | | MD-200A8X | Desktop Microphone | | | | | MH-31A8J | Hand Microphone | | | | | MH-36E8J | DTMF Mobile Microphone | | | | | Miscellaneous | | | | MHG-1 | FT-450 Side Carry Handle | | | | | Power Supplies | | | | FP-1030A | 30A Power Supply 110V | | | | | Speakers | | | | MLS-100 | External Speaker (12 Watt Peak) | | | |
