YAESU SSM-75E (01) PDF Document

The YAESU SSM-75E microphone has several switches with specific functions:

① PTT Switch: Switches between Transmit and Receive. Press to transmit and release to receive.

② DWN/UP Key: These keys can be used to manually scan the frequency upward or downward. The amount of frequency change depends on the operation mode.

③ MUTE Key: While pressing the MUTE key, the receiver audio from the speaker will be muted.

④ Microphone: Speak into the microphone in a normal tone of voice with the microphone 5 cm away from the mouth.

⑤ P1 key: This key toggles the ON/OFF lock for the MAIN Dial knob. When “Lock” is ON, the MAIN Dial knob can still be turned, but the frequency will not change, and “LOCK” appears in the frequency display. It is the same function as the [LOCK] key on the front panel of the transceiver.

⑥ P2 key: The current operation status can be stored in a dedicated memory channel (QMB: Quick Memory Bank) with one touch. It is the same function as the [QMB] key on the front panel of the transceiver.

⑦ P3 key: Pressing this key momentarily exchanges the VFO-A and VFO-B frequency data. It is the same function as the [A/B] key on the front panel of the transceiver.

⑧ P4 key: This key toggles frequency control between VFO and the memory system. It is the same function as the [V/M] key on the front panel of the transceiver.

The amount of frequency change depends on the operation mode. The default settings are as follows:

The frequency change step can also be changed in the setting menu:

To adjust the microphone gain on your YAESU SSM-75E transceiver, follow these steps:

Step 1. Touch the Meter Display and then touch “ALC” to select the ALC Meter.

Step 2. Press the [FUNC] knob.

Step 3. Touch [MIC GAIN].

Step 4. Key TX and adjust the [FUNC] knob to set the input level of the Microphone Amplifier to the position where the ALC Meter needle does not exceed the ALC zone on the audio peaks.

The AMC (Automatic Microphone Gain Control) regulates the microphone audio so that distortion does not occur, even if excessive audio is input. The AMC function only works in SSB, AM, DATA-L and DATA-U modes. To adjust it:

Step 1. Touch the Meter Display and then touch “COMP” to select the COMP Meter.

Step 2. Press the [FUNC] knob.

Step 3. Touch [AMC LEVEL].

Step 4. Activate the transmit and speak into the microphone while adjusting the AMC level with the [FUNC] knob.

Step 5. Adjust the AMC to a point where the COMP Meter deflection does not exceed “10dB” on the audio peaks.

Setup is completed.

Operate the [FUNC] knob to make the following settings:

PROC LEVEL: Adjust the level of the speech processor function.

RF POWER: Adjust the transmit power.

MONI LEVEL: Adjust the monitor level.

The last function used is retained in the [FUNC] knob so it can be easily set by operating the [FUNC] knob. Normally, it is suggested to utilize the [FUNC] knob as the [LEVEL] knob for the spectrum scope.

The Parametric Microphone Equalizer function is activated only in SSB, AM, and FM modes. To set it up:

Step 1. Set the RF output power to a minimum value. It is recommended to connect a dummy load and monitor the signal on a separate receiver to prevent interference.

Step 2. Press the [FUNC] knob.

Step 3. Touch [MIC EQ]. The Parametric Microphone Equalizer function is activated.

Step 4. Press the [FUNC] knob.

Step 5. Touch [MONI LEVEL].

Step 6. Rotate the [FUNC] knob to adjust the Monitor level.

Step 7. Press the [FUNC] knob.

Step 8. Select [OPERATION SETTING]→[TX AUDIO].

Step 9. Rotate the [FUNC] knob to find Menu items [PRMTRC EQ1 FREQ] through [PRMTRC EQ3 BWTH] for when the speech processor is disabled, or [P PRMTRC EQ1 FREQ] through [P PRMTRC EQ3 BWTH] for when the speech processor is engaged.

Step 10. Rotate the [FUNC] knob, or touch “<” or “>” on either side of the value to adjust a particular Menu item.

Step 11. Press and hold the PTT switch, and speak into the microphone while listening to the effect of the adjustments. Make several passes through each adjustment area to ensure optimum settings are achieved. It is best to wear headphones connected to a monitor receiver.

Step 12. When all adjustments are satisfactory, press the [FUNC] knob to save the new settings.

Step 13. Touch [BACK] several times to return to normal operation.

To activate the equalizer:

Step 1. Adjust the MIC gain as described previously.

Step 2. Press the [FUNC] knob.

Step 3. Touch [MIC EQ]. The function is now activated.

Step 4. Press the PTT switch on the microphone, and speak into it in a normal voice level.

To cancel the equalizer:

Repeat steps 2 and 3 above, and choose “OFF” in step 3.

Before you begin, note the following:

Interconnections to FTDX10:

Connect “ATAS-120A” to the ANT terminal of the FTDX10 with a coaxial cable. Observe these precautions:

• Turn off the external power supply switch and the FTDX10 power supply switch first before connecting the cables.

• Do not plug or unplug the connector of the antenna cable with wet hands or during transmission.

• Grounding is required for the ATAS-120A. Ensure the antenna base is in contact with the car body for proper grounding.

Setup the transceiver:

Step 1. Press the [FUNC] knob.

Step 2. Select [OPERATION SETTING] → [GENERAL] → [TUNER SELECT].

Step 3. Rotate the [FUNC] knob, or touch “<” or “>” on either side of the value to select “ATAS”.

Step 4. Press the [FUNC] knob to save the new setting.

Step 5. Touch [BACK] several times to return to normal operation. The “ATAS” icon will appear in the display.

Tuning Operation:

Step 1. Press the [TUNE] key to begin automatic tuning.

• The transmitter will engage, and the “ATAS” icon will blink while tuning is in progress.

• When the optimum tuning point has been reached, the transceiver will return to receive, and the “ATAS” icon will again glow steadily.

• Note: When using the ATAS-120A for the first time, tuning may not be performed for about 1 minute until the FTDX10 recognizes the antenna.

Manual Tuning:

Press the PTT switch on the microphone to transmit and then press the UP/DWN button on the microphone to adjust the antenna until the meter indicates the minimum SWR. The meter on the screen will automatically change to the SWR meter.
