Before You Begin Antenna Considerations The FT-991A is designed for use with any antenna system providing a 50 Ohm resistive impedance at the desired operating frequency. While minor excursions from the 50-Ohm specification are of no consequence, if the Standing Wave Ratio (SWR) present at the Antenna jack is greater than 3:1, the transceiver’s Automatic Antenna Tuner may not be able to reduce the impedance mismatch to an acceptable value.
Before You Begin Grounding The FT-991A 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.
Before You Begin Connection of Antenna and Power Cables Please follow the outline in the illustration regarding the proper connection of antenna coaxial cables, as well as the DC power cable. The DC power connector for the FT-991A must only be connected to a DC source providing 13.8 Volts DC (±15 %), and capable of at least 23 Amperes of current. Always observe proper polarity when making DC connection: The RED DC power lead connects to the Positive (+) DC terminal.

The Contour is set to either suppress, or boost specific frequency components, and thus enhances the sound and readability of a received signal. 1. Press the F(M-LIST) button to display the function menu list. Touch [CONT] to activate the CONTOUR function and set the MULTI knob as the CONTOUR adjustment knob. 2. Touch [CONT ] on the TFT display.
Interference Rejection IF SHIFT Operation (SSB/CW/RTTY/DATA Modes) IF SHIFT permits moving the DSP filter passband higher or lower, without changing the pitch of the incoming signal, and thus reduces or eliminates interference. Because the tuned carrier frequency is not varied, there is no need to re-tune the operating frequency to eliminate the interference. The total passband tuning range for the IF SHIFT system is ±1.2 kHz. 1. Press the F(M-LIST) button to display the function menu list.
Interference Rejection WIDTH (IF DSP Bandwidth) Tuning (SSB/CW/RTTY/DATA Modes) The IF WIDTH tuning system allows you to vary the width of the DSP IF passband, to reduce or 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. Press the F(M-LIST) button to display the function menu list.
Interference Rejection WIDTH (IF DSP Bandwidth) Tuning (SSB/CW/RTTY/DATA Modes) Using IF SHIFT and WIDTH Together The IF SHIFT and Variable IF WIDTH features together form a very effective interference-fighting filtering system. For example, in Figure “A”, you can see how interference has appeared both on the high and low sides of the desired signal. Touch [WIDTH] on the LCD, the interference from one side can be eliminated (Figure “B”).
Interference Rejection NARROW (NAR) One-Touch IF Filter Selection Press the F(M-LIST) button to display the function menu list.

Interference Rejection IF NOTCH Filter Operation (SSB/CW/RTTY/DATA/AM Modes) The IF NOTCH filter is a highly effective system that allows cutting out an interfering beat note or other carrier signal from inside the receiver passband. 1. Press the F(MLIST) button to show the functions listed on the TFT display. 2. Touch [ NOTCH ] on the TFT display. The Notch function will be set to “ON”. F(M-LIST) Button NOTCH indicator NOTCH level indicator MULTI Knob 3.
Interference Rejection Digital NOTCH Filter (DNF) Operation The Digital NOTCH Filter (DNF) is an effective beat-canceling filter that can null out a number of interfering beat notes inside the receiver passband. Because this is an Auto-Notch feature, there is no adjustment knob associated with this filter. Advice: If a very strong interfering carrier is encountered, we recommend using the IF NOTCH filter first, as it is the most effective notching tool in the receiver section. 1.
Tools for Comfortable and Effective Reception RF Gain The RF Gain control provides manual adjustment of the gain levels for the receiver RF and IF stages, to account for noise and signal strength conditions at the moment. 1. The RF GAIN knob should, initially, be rotated to the fully clockwise position. This is the point of maximum receiver sensitivity. 2. Counter-clockwise rotation of the RF GAIN knob will gradually reduce the system gain.

Advice: The APF bandwidth can be selected from NARROW/MEDIUM/WIDE via the Menu item “113 APF WIDTH”. 4. To cancel the APF action, touch [APF] on the LCD.
Tools for Comfortable and Effective Reception AGC (Automatic Gain Control) The AGC system is designed to help compensate for fading and other propagation effects. The AGC characteristics can be individually set for 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 F(M-LIST) button, then touch [AGC] on the LCD repeatedly to select the desired receiver-recovery time constant.
Tools for Comfortable and Effective Reception Adjustable Receiver Audio Filter The FT-991A includes an adjustable receiver audio filter, that provides precise, independent control of the low; and upper audio ranges. 1. Press the MENU button to enter the Menu mode. 2.
SSB/AM Mode Transmission ON/OFF Switch BAND Button MODE Button 1. Press the BAND button to show the band list, and then touch a band key corresponding to the Amateur band on which you wish to operate. Press the BAND button again, to close the band list screen. 2. Press the MODE button to show the mode list, and then select the operating mode by touching the corresponding key. Press the MODE button again, to close the mode list screen.
SSB/AM Mode Transmission Advice: ALC meter deflection may be caused by excessive drive power, but also by reflected power detected in the antenna system. If the antenna impedance presented to the transceiver is other than 50 Ohms, ALC meter action may be observed that is not related to the proper setting of [MIC GAIN] on the LCD. Therefore, we recommend that you make [MIC GAIN] adjustments into a dummy load or antenna system presenting impedance very close to 50 Ohms.
Using the Automatic Antenna Tuner The Automatic Antenna Tuner (hereinafter referred to as the “ATU”) built into each FT-991A is designed to ensure a 50-Ohm load for the final amplifier stage of the transmitter. Advice: Because the ATU of the FT-991A is located inside the station, it only adjusts the impedance presented to the transceiver at the station end of your coaxial cable feedline. It does not “tune” the SWR at the antenna feed point itself.
Using the Automatic Antenna Tuner About ATU Operation Figure 1 depicts a situation where normal tuning via the ATU has been successfully completed, and the tuning data has been stored in the ATU memory. The antenna system as seen by the transmitter is shown. In Figure 2, the operator has changed frequency, and the “HI-SWR” icon has appeared. The operator presses and holds in the TUNE button for one second to begin impedance matching using the ATU.
Enhancing Transmit Signal Quality Parametric Microphone Equalizer (SSB/AM mode) The FT-991A includes a unique Three-Band Parametric Microphone Equalizer that provides precise, independent control over the low, mid and treble ranges in the voice waveform. You may utilize one group of settings when the speech processor is off and use an alternate group of settings when the speech processor is on. The speech processor feature is described in the next chapter.
Enhancing Transmit Signal Quality Parametric Microphone Equalizer (SSB/AM mode) 8. Press and hold the PTT switch, and speak into the microphone while listening to the effect of the changes you are making. Because the overall effect on the sound will change with each adjustment, make several passes through each adjustment area, to be sure that you achieve the optimum settings. 9. When all adjustments have been completed, touch [ENTER] on the LCD to save the new settings.

Enhancing Transmit Signal Quality Using the Speech Processor (SSB Mode) The FT-991A Speech Processor is designed to increase “talk power” by increasing the average power output (via a sophisticated compression technique) and adjusting the audio quality to the menu settings (“130 P-PRMTRC EQ1 FREQ”, “133 P-PRMTRC EQ2 FREQ”, “136 P-PRMTRC EQ3 FREQ”). The result is improved intelligibility when conditions are difficult. F(M-LIST) Button 1. Adjust [MIC GAIN] on the TFT display, as described on page 59. 2.
Enhancing Transmit Signal Quality Adjusting the SSB Transmitted Bandwidth (SSB Mode) For SSB transmission, a default bandwidth of 2.4 kHz is available. This bandwidth provides reasonable fidelity along with good talk power, and is the typical bandwidth used for decades for SSB transmission. The transmit bandwidth may be varied by the operator, to provide different levels of fidelity or talk power, according to individual preferences. Here are the steps to adjust the SSB transmit bandwidth: 1.
Transmitter Convenience Features Voice Memory (SSB/AM modes) You may utilize the Voice Memory capability of the FT-991A for repetitive messages.
