- Page 2 Besides, writing a User’s Manual is a great way to learn any system. Well, I have to say, I was wrong about the first item. It turns out the Yaesu Manual is very good. It is just that the FT-450 is a very complex machine. I continued with the effort because my second reason is still valid.

(adaptable). Since there are literally hundreds of settings possible on the FT-450, a button, knob, or dial may be used to control more than one function. The less often changed values are set by a sequence of buttons and/or dials. - Page 6 YAESU HF/50 mHz Transceiver FT-450 User’s Manual CONTROL STATE FUNCTION ON/OFF T-PRESS - Toggle system ON/OFF PRESS Step DSP contour, notch, digital noise reduc, width, OFF ATT/IPO PRESS Step through combinations of ATT and IPO off and on T-PRESS CW...

Needless to say, the 12 volts must already be supplied to the unit. The power switch is also used to reset memory and/or adaptation in the FT-450. Warning: Do not perform any of the first three following steps unless you are prepared to lose information: 1) Turning the power on while holding the “F... -

Communications Mode The FT-450 transceiver is designed to communicate using Lower Side Band (LSB), Upper Side Band (USB), Continuous Wave (CW, i.e. Morse code), Data (DATA), Amplitude Modulation (AM), or Frequency Modulation (FM). -

The frequency lock may be released by pressing “LOCK” again. In addition to the display, the FT-450 is able to announce the current frequency through the speaker or headset. To hear the frequency, f-press the “VOICE” button (2 upper button from the right). -

YAESU HF/50 mHz Transceiver FT-450 User’s Manual Extracting the Signal from the Noise Every stage of the FT-450 Transceiver contributes to the effort to improve the signal to noise ratio. In order to deal with the wide dynamic range of input signals, the operator may optionally insert 20 db of attenuation or disable the radio frequency (RF) amplifier in what is called intercept point optimization (IPO). -

Page 14: Radio Frequency Volume Control
YAESU HF/50 mHz Transceiver FT-450 User’s Manual The FT-450 attempts to maintain a constant audio level (assuming the signal is strong enough). In general, we want the Automatic Gain Control (AGC) to respond quickly during CW or DATA transmissions. However, when speech is involved we want the system to react more slowly so that voice inflections can be heard. -

YAESU HF/50 mHz Transceiver FT-450 User’s Manual addition, if CW mode, the display also shows whether the injected beat frequency is LSB or USB. When the automatic antenna tuner is engaged, the TUNER indicator is lighted. As long as the system is receiving (or squelch is open) the BUSY indicator is lighted. -

Channel Memories The FT-450 contains 508 memory channels as well as M-TUNE, VFO-A, VFO-B, QUICK, and HOME. The memory channels may be addressed one of two ways per Table 7 according to the setting in adaptation. -

Table 8 – Contents of Each Memory Channel Tuning of the VFO Setup Memory The FT-450 Transceiver maintains three active VFO setups; M-TUNE, VFO-A and VFO-B. One of these three setups, known as the primary VFO, is indicated on the bottom right hand corner of the display. -

YAESU HF/50 mHz Transceiver FT-450 User’s Manual Channels Memories See Table 7 for channel designation. 5.6.1 Recall Simply press the “MW/V/M” button and then select the desired active channel with the “DSP/SEL” knob. If memory groups is adapted ON, pressing the “DSP/SEL” knob highlights the group number and the DSP/SEL knob now steps one active group at a time. -
Page 20: Vfo Memory Scanning
Semi-automatic Keyer The FT-450 contains a semi-automatic keyer for CW transmission. It has the advantage (and to some, disadvantage) of making the code stream more uniform. The relative size of dots, dashes and spaces a standard size for a given code speed. -

When you are done, be sure to restore the BK-IN function. For CW reception training, the FT-450 has a built in CW Training feature, which sends random Morse Code five-character groups via the sidetone (heard in the speaker). The groups may be numeric, alpha or a mixture of both alpha and numeric characters. -
