[. . . ] FT DX 9000MP Operation Manual DESCRIPTION GENERAL DESCRIPTION We wish to take this opportunity to thank you for your purchase of the FT DX 9000MP Transceiver!The FT DX 9000MP is the culmination of a four-year design project. But it also is the product of our company's fifty years of engineering, design, and manufacturing know how. As pioneers in the development of SSB, we have led the technological advances in Amateur Radio communications over the last half century. [. . . ] See the charts for further information about the typical response curves for these highly useful filters, which oftentimes can significantly enhance reception. NOTE It is possible to mute the audio from the speaker(s), if desired; see page 40. To mute the audio from the Main receiver (left speaker), press the [MUTE(A)] switch. To mute the audio from the Sub receiver (right speaker), press the [MUTE(B)] switch. FILTER A [LOW CUT] Switch FILTER B [LOW CUT] Switch FILTER B FILTER A [HIGH CUT] Switch [HIGH CUT] Switch NORM 300 500 700 1k 2. 4k NORM LOW CUT The audio filter is disabled. Audio below 300 Hz is attenuated at a rate of -6 dB/octave. Audio below 500 Hz is attenuated at a rate of -6 dB/octave. HIGH CUT Audio above 700 Hz is attenuated at a rate of -6 dB/octave. Audio above 1000 Hz is attenuated at a rate of -6 dB/octave. Audio above 2400 Hz is attenuated at a rate of -6 dB/octave. The audio filter is disabled. ADVICE It is possible to combine the speakers' audio outputs, so as to enhance the tonal fidelity from bass through treble; see page 40. Pressing the [OUTPUT(B)] switch (once the "[A+B]" switch has been pressed) will combine the audio from the two speakers, effectively doubling the total speaker aperture.

The operating mode is selected using the [MODE] switches to the left of the [MAIN Tuning Dial] knob, and the VFO (A or B) to which the selection is applied is selected by pressing the [A] or [B] switch above the Mode keys. Press the [A] or [B] key to select the desired VFO, then press the [LSB] or [USB] key to select one of the SSB modes. POINT OINT: QUICK POINT By convention, LSB is used in the 7 MHz and lower Amateur bands for SSB communication, and USB is used on the 14 MHz and higher bands (the 10 MHz band is used for CW and data modes only). Rotate the [MAIN Tuning Dial] knob to adjust the operating frequency. Alternatively, if using the optional MD-200A8X Desktop Microphone, you may use the Up/Down scanning buttons to sweep up or down the current band. VICE: ADVICE Be sure to verify that the microphone you are using is enabled for operation via the Menu. There are two microphone jacks (the front panel's three-pin XLR ("Cannon") connector, and the rear panel's 8-pin round connector), and either jack may be chosen independently for SSB, AM, and FM operation. 3. Press the microphone's PTT (Push To Talk) switch to begin transmission; speak into the microphone in a normal voice level. VICE: ADVICE The "TX" indicator will light up in the frequency display area, confirming that transmission is in progress. When transmitting in the AM mode, rotate the [RF PWR] control so as to set a maximum (carrier) power output of 50 Watts. Release the PTT switch at the end of your transmission. [. . . ] This key is used for gaining access to the Menu system, for configuring various transceiver characteristics. menu operation is described in detail, in this manual, beginning on page 128. Important note: Pressing this key momentarily activates the Menu, and the Menu selections will appear on the TFT screen; once you are finished, you must press and hold in the [MNU] key for two seconds to save any configuration changes (momentarily pressing [MNU] key to exit will not save the changes). These are the "Function" keys for the various functions associated with each page of the TFT's operational capability. [. . . ]
