INTERFACING TO OTHER LINEAR AMPLIFIER
The T/R control line is a transistor open collector circuit, capable of handling positive amplifier relay coil voltages of up to +50V DC and current of up to 400 mA. If you plan on using multiple linear amplifiers for different bands, you must provide external band-switching of the Lin Tx relay control line from the TX GND OUT line at the LINEAR jack. Important Note!
Do not exceed the maximum voltage or current ratings for the TX GND OUT line at the LINEAR jack. This line is not compatible with negative DC voltages, nor AC voltages of any magnitude. Most amplifier control relay systems require only low DC voltage/current switching capability (typically, +12V DC at 25 ~ 75 mA), and the switching transistor in the FT-450 will easily accommodate such amplifiers.

[AF GAIN] button

ADVICE: If you are using the speaker for monitoring, instead of headphones, excessive advancement of the [AF GAIN] knob can cause feedback to occur. Additionally, this feedback can cause the VOX system to hang up in a loop, making it impossible to return to receive. Therefore, we recommend the use of headphones, if at all possible, or the minimum usable setting of the [AF GAIN] knob, if the speaker must be used. Because the Monitor feature utilizes a sampling of the transmitters DSP signal, it can be very useful for checking the adjustment of the Speech Processor or Microphone Equalizer on SSB, and for checking the general signal quality on AM and FM.

TONE SEARCH SCANNING
In operating situations where you dont know the CTCSS tone being used by another station or stations, you can command the radio to listen to the incoming signal and scan in search of the tone being used. Two things must be remembered in this regard: You must be sure that your repeater uses the same tone type (CTCSS). Some repeaters do not pass the CTCSS tone; you may have to listen to the station(s) transmitting on the repeater uplink (input) frequency in order to allow Tone Search Scanning to work. To scan for the tone in use: 1. Set the radio up for CTCSS operation (see the previous discussion). The icon will appear on the display. 2. Press and hold the [F] button for one second to enter the Menu mode. The icon will appear on the display. 3. Rotate the [DSP/SEL] knob to select the menu item TONE F TONE F. 4.

When the radio detects the correct tone, it will halt on that tone, and audio will be allowed to pass. 7. Press the [DSP/SEL] knob to lock in that tone. 8. Press and hold the [F] button for one second to return to normal operation. NOTE: If the Tone Scan feature does not detect a tone, it will continue to scan indefinitely. When this happens, it may be that the other station is not sending any tone. You can press the [PMS/SCAN] button to halt the scan at any time.

BASIC SETUP

1. Press the [MODE ]/[MODE ] buttons several times to indicate both the and icons on the display. Engage the RTTY operation using LSB injection, which is generally used in the Amateur service. 2. When you begin typing on your TU or computer keyboard, the command to transmit should automatically be sent to the transceiver, causing it to enter the transmit mode. NOTE: If you anticipate making data transmissions of longer than a few minutes, we recommend that you reduce the transmitter power to 1/2 ~ 1/3 of its normal maximum via Menu Item RFPOWER RFPOWER. RFPOWER QUICK POINT: In the FT-450, RTTY is a mode defined as being an FSK mode, whereby the closing and opening of a keying line (to ground) causes the Mark/Space tones to alternate. The RTTY mode is not an AFSK based mode in this transceiver, and the AFSK output tones from a TNC will not cause Mark/Space shifting to occur. Use the Packet mode for AFSK-based Baudot and other data modes. ADVICE: There is no adjustment of the FSK input level (FSK IN of the DATA jack) on the rear panel; please make any needed level adjustments at the TU side. The Mark/Space Shift utilized in most Amateur RTTY operation is 170 Hz. Other shifts may be configured, however, using Menu Item RTY SFT RTY SFT. The FT-450 is set up for high tone operation (centered on 2125 Hz) by default, but you may configure it for low tone (1275 Hz) operation using Menu Item RTY TON RTY TON. You may find that you are unable to decode some RTTY stations, even if they are of sufficient signal strength. If this is observed, there may be a Mark/Space polarity problem between your station and the other station. If so, try setting Menu Item RTYRPOL to REV (Reverse) to see if RTYRPOL RTYRPOL that permits copy. A separate Menu Item permits reversal of your transmitters Mark/Space polarity: RTYTPOL RTYTPOL.

The Real DX Receiver! The 67.899 MHz 4 pole roofing filter (MCF) and 8 band-pass filters at the RF state provide excellent suppressions of out-ofband interference.
The interference-filtering begins in the "RF" stages, with a double conversion superhetrodyne (1st IF 67.899 MHz / 2nd IF 24 kHz) system. And the 8 band-pass filters at the RF input that help eliminate out-of-band interference, followed by the RF AMP (2SK520 x 2) to led into the active DBM (1st local) will promise its excellent dynamic range. At its 1st IF stage, a powerful and excellent shape factor 4 pole roofing filter with a bandwidth of 10 kHz substantially reduces adjacent signal interference. Then, YAESUs high performance DSP at the 2nd IF stage / 24 kHz permits easy management of AGC, interference rejection, audio tone control, and noise reduction, for clear and quiet reception. The 20 dB ATT (Attenuator) and IPO (Intercept Point Optimization) feature allow the operator to optimize the characteristics of the receiver front end to improve its dynamic range.
