INSTALLATION CONNECTION OF ANTENNA AND POWER SUPPLY The FT-450 is designed for use with any antenna system providing a 50 Ohm resistive impedance at the desired operating frequency. Every effort should be made to ensure the impedance of the antenna system is as close as possible to the specified 50-Ohm value. Note that the “G5RV” type antenna does not provide 50-Ohm impedance on all HF Amateur bands, and an external wide-range antenna coupler must be used with this antenna type.
INSTALLATION GROUNDING The FT-450 transceiver, like any other HF communications apparatus, requires an effective ground system for maximum electrical safety and best communications effectiveness. A good ground system can contribute to station efficiency in a number of ways: It can minimize the possibility of electrical shock to the operator. It can minimize RF currents flowing on the shield of the coaxial cable and the chassis of the transceiver.
INSTALLATION VL-1000 LINEAR AMPLIFIER INTERCONNECTION Be sure that both the FT-450 and VL-1000 are turned off, then follow the installation recommendations contained in the illustration. Note: Ì Please refer to the VL-1000 Operating Manual for details regarding amplifier operation. Ì Please do not attempt to connect or disconnect coaxial cables when your hands are wet. HF Beam Antenna To link the FT-450 and VL1000 Power switches, set the VL-1000 REMOTE switch to the “ON” position.

CONVENIENCE FEATURES RECEIVER OPERATION (FRONT END BLOCK DIAGRAM) The FT-450 includes a wide range of special features to suppress the many types of interference that may be encountered on the HF bands. However, real world interference conditions are constantly changing, so optimum setting of the controls is somewhat of an art, requiring familiarity with the types of interference and the subtle effects of some of the controls.
CONVENIENCE FEATURES ATT/IPO (ADJUST THE RECEIVING SENSITIVITY) You may reduce the receiving signal strength to 20 dB when extremely strong local signals or high noise degrade reception. You may optimize the characteristics of the receiver front-end, for best reception, depending on the noise levels and the signal strengths. Press the [ATT/IPO] button several times to set the desired selection, per the chart below.
CONVENIENCE FEATURES AGC (TOOL FOR COMFORTABLE AND EFFECTIVE RECEPTION) The AGC system is designed to help compensate for fading and other propagation effects, with characteristics that can be of particular value on each operating mode. The basic objective of AGC is to maintain a constant audio output level once a certain minimum threshold of signal strength is achieved. Press the [AGC] button repeatedly to select the desired receiver-recovery time constant.
CONVENIENCE FEATURES CONTOUR (INTERFERENCE REJECTION “SIGNALS WITHIN 3 KHZ”) The Contour filtering system provides a gentle perturbation of the IF filter pass band. so as to suppress or enhance particular frequency components in five steps, thus improving the sound and/or readability of a received signal. 1. Press the [DSP] button several times to set the “>” icon to the “CONTOUR” indicator of the DSP Graphic Display on the display. 2. Press the [DSP/SEL] knob to engage the contour filter. 3.
CONVENIENCE FEATURES SHIFT (INTERFERENCE REJECTION “SIGNALS WITHIN 3 KHZ”) IF Shift allows you to vary the DSP filter passband higher or lower, without changing the pitch of the incoming signal, so as 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.
CONVENIENCE FEATURES WIDTH (INTERFERENCE REJECTION “SIGNALS WITHIN 3 KHZ”) The IF Width tuning system allows you to vary the width of the DSP IF passband with three steps (FM: two steps), so as 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. 1.
CONVENIENCE FEATURES NOTCH (INTERFERENCE REJECTION “SIGNALS WITHIN 3 KHZ”) 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. 1. Press the [DSP] button several times to set the “>” icon to the “NOTCH” indicator of the DSP Graphic Display on the display. 2. Press the [DSP/SEL] knob to engage the IF Notch filter. 3. Rotate the [DSP/SEL] knob to adjust the center frequency of the IF Notch Filter.
CONVENIENCE FEATURES DNR (INTERFERENCE REJECTION “SIGNALS WITHIN 3 KHZ”) The Digital Noise Reduction (DNR) system is designed to reduce the level of random noise found on the HF and 50 MHz bands, and it is especially effective during SSB operation. Any of eleven different noise-reduction algorithms can be selected.
CONVENIENCE FEATURES RF GAIN The RF Gain controls provide manual adjustment of the gain levels for the receiver RF and IF stages, to compensate for noise and/or signal strength conditions at the moment. The [SQL/RF GAIN] knob should, initially, be rotated to the fully clockwise position. This is the point of maximum sensitivity, and counter-clockwise rotation will gradually reduce the system gain.

Two things must be remembered in this regard: You must be sure that your repeater uses the same tone type (CTCSS).
MEMORY OPERATION CONVENIENT MEMORY FUNCTIONS The FT-450 contains 500 regular memories, labeled “MEM-001” through “MEM-500”, two Home channels, one for the HF band and another for the 50 MHz band, two special programmed limit memory pairs, labeled “MEMP1L/MEM-P1U” and “MEM-P2L/MEM-P2U”, one QMB (Quick Memory Bank) memory, one Alaska Emergency Frequency Channel (5167.5 kHz), and five 60-meter (5 MHz) band channels.
MEMORY OPERATION MEMORY GROUPS Memory channels may be organized into as many as 10 convenient groups, for easy identification and selection. For example, you might want to set aside memory groups for AM BC stations, shortwave broadcast stations, contest frequencies, repeater frequencies, and PMS limits, or any other groupings you like. Each memory group is capable of holding up to 50 memory channels (the Group size is fixed).
MEMORY OPERATION REGULAR MEMORY OPERATION The Regular Memory of the FT-450 allows storage and recall of up to 500 memories, each storing frequency, mode, and a wide variety of status information detailed previously. Memories may be organized into as many as ten Memory Groups, and additionally you get two pairs of band-limit (PMS) memories along with one QMB (Quick Memory Bank) memory and two Home channels.
