When transmitting in SSB or AM mode, the FTX-1 transmit audio circuit can be set to the optimum operating level by individually adjusting the input and output gains of the microphone amplifier. The AMC (Automatic Microphone Gain Control) regulates the microphone audio so that distortion does not occur, even if excessive audio is input.

1. Touch the Meter Display and then touch "ALC" to select the ALC Meter.
2. Press and hold the [FUNC] knob.
3. Touch [MIC GAIN].
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.

1. Touch the Meter Display and then touch "COMP" to select the COMP Meter.
2. Press and hold the [FUNC] knob.
3. Touch [AMC LEVEL].
4. Activate the transmit and speak into the microphone while adjusting the AMC level with the [FUNC] knob.
5. Adjust the AMC to a point where the COMP Meter deflection does not exceed "10dB" on the audio peaks.

Setup is completed.

The AMC function only works in LSB, USB, AM, AM-N, DATA-L, DATA-U and PSK modes. It does not work in other modes.

The FTX-1 Speech Processor is designed to increase "talk power" by increasing the average power output of the transmitted SSB signal.

1. Adjust the MIC gain as described on the previous page.
2. Press and hold the [FUNC] knob.
3. Touch [PROC LEVEL].
4. Touch the Meter area on the display to select the "COMP" meter.

The transmit meter becomes the "COMP" meter.

5. Press the PTT switch on the microphone, and speak into the microphone in a normal voice level.
6. Adjust the [FUNC] knob to set the compression level within 10 dB.

• The Transmit Monitor is a helpful aid to verify proper adjustment of the Compression level.
• The "PROC" indicator lights in the display.

Rotate the [FUNC] knob to the left to turn the speech processor function "OFF".

Turn the [FUNC] knob to adjust the RF power output.

1. Press and hold the [FUNC] knob.
2. Touch [RF POWER].
3. Rotate the [FUNC] knob to adjust the RF power.

Use the Monitor feature to listen to the quality of the transmitted signal.

1. Press and hold the [FUNC] knob.
2. Touch [MONI LEVEL].
3. Rotate the [FUNC] knob to adjust the Monitor level.
4. To cancel the monitor function, turn the [FUNC] knob to set "MONI LEVEL" to "OFF".

Transmit audio monitor is not activate in the FM, FM-N, DATA-FM, D-FM-N, AM and AM-N modes.

The clarifier is used to adjust the transceiver receive frequency to match the other station transmit frequency and improve the audio; or to shift the transmit frequency of this station when the transmit frequency of the contact station is shifted.

The display will indicate "CLAR RX" → "CLAR TX" → "CLAR RXTX" in red, each time the [CLAR] key is pressed, and the clarifier will activate.

To adjust the offset frequency of the clarifier, turn the "MAIN DIAL" for the MAIN-side, or the "SUB DIAL" for the SUB-side.

To turn the clarifier OFF, repeatedly press the [CLAR] key until the Clarifier status is not displayed.

To clear out the programmed clarifier offset altogether, and reset it to "zero," press and hold the [CLAR] key.

If the transmit frequency of the contact station deviates, this receiver clarifier frequency can be changed leaving this transmit frequency unchanged.

1. Press the [CLAR] key.
2. Rotate the MAIN dial knob to change only the receive frequency.

When the receive frequency is offset by +20Hz.

Offsets of up to ±9995Hz may be set using the Clarifier.

After changing the receiver frequency with RX Clarifier, the transmitter frequency can be set to the same frequency as the receiver.

1. After offsetting the receiver frequency, press the [CLAR] key twice. The transmit frequency becomes the same as the receive frequency. "CLAR RX" of the display changes to "CLAR RXTX".
2. Press the [CLAR] key twice, only the receive frequency returns to the offset state. "CLAR RXTX" of the display changes to "CLAR RX".

The transmit frequency can be changed without moving the receive frequency of the transceiver. Normally, the clarifier is used to move only the receive frequency and compensate for the deviation of the transmission frequency of the contact station, however alternatively, only the transmit frequency can be moved without changing the transmitter. When responding to an operator that is called by a large number of stations such as in a contest, etc., the response rate may increase if the transmit frequency is moved slightly.

1. Press the [CLAR] key twice.
2. Rotate the MAIN dial knob to change only the transmit frequency.
3. To cancel Clarifier operation, press the [CLAR] key twice.

Offsets of up to ±9995Hz may be set using the Clarifier. To clear out the programmed clarifier offset altogether, and reset it to "zero", press and hold the [CLAR] key.

When the transmit frequency is offset with the TX Clarifier, it can be reset to the same frequency as the TX frequency offset from the receive frequency.

1. After offsetting the transmit frequency, press the [CLAR] key. The receive frequency becomes the same as the transmit frequency. "CLAR TX" of the display changes to "CLAR RXTX".
2. Press the [CLAR] key three times, only the transmit frequency returns to the offset state. "CLAR RXTX" of the display changes to "CLAR TX".

Equipped with a QRP mode that allows you to set the maximum transmission output to "5W" on all bands. This is useful for QRP contests.

1. Press and hold the [FUNC] knob.
2. Select [OPERATION SETTING] → [TX GNRL].
3. Rotate the [FUNC] knob to select [QRP MODE].
4. Rotate the [FUNC] knob, or touch "<" or ">" on either side of the value to select "ON" or "OFF".
5. Press the [FUNC] knob, or wait for about 3 seconds to save the setting.

The Digital Noise Reduction (DNR) system is designed to reduce the level of ambient noise. The (DNR) system is especially effective during SSB operation. Any of 10 different noise-reduction algorithms can be selected; each of these algorithms was created to deal with a different noise profile. You will want to experiment with the DNR system to find the best setting corresponding to the noise currently being experienced.

The DNR function can be operated individually for MAIN-side and SUB-side.

1. Press and hold the [FUNC] knob.
2. Touch [DNR].
3. Rotate the [FUNC] knob to adjust the DNR level.

The "DNR" indicator lights in the display.

4. Rotate the [FUNC] knob to the left to turn the DNR function "OFF".

The Voice Memory capability of the FTX-1 may be used to store and replay often repeated messages. The Voice Memory includes five memories.

The Automatic Antenna Tuner (ATU) is built into each FTX-1 optima. The ATU is designed to ensure that a 50-Ohm antenna impedance load is presented to the final amplifier stage of the transmitter.

• Because the FTX-1 optima ATU is located inside transceiver, it can only adjust the impedance presented to the transceiver end of the coaxial cable feedline. It does not "tune" the SWR at the antenna feed point itself.
• When designing and building an antenna system, we recommend that every effort be made to also ensure a low SWR at the antenna feed point.
• The ATU in the FTX-1 optima is designed to match impedances within the range of 16.7 Ohms to 150 Ohms, corresponding to an SWR of 3:1 or less on the HF amateur bands (6 m amateur band: 25 Ohms to 100 Ohms, corresponding to an SWR of 2:1 or less). Accordingly, simple non-resonant whip antennas, along with random-length wires and the "G5RV" antenna (on most bands) may not be within the impedance matching range of the ATU.
• The built-in antenna tuner cannot be used with an antenna connector connected to an external antenna tuner.

1. Press and hold the [FUNC] knob.
2. Touch [TUNER] to place the ATU in the transmit line (no adjustment or tuning will occur yet). While the ATU function is activated, the "TUNE" will be displayed.
3. Touch [ANT TUNE] key to begin automatic tuning. The transmitter will be engaged, and "TUNE" will be blinks while tuning is in progress.
4. To disengage the ATU from the transmit line, touch [TUNE].

• Always listen on the operating frequency before beginning the tuning process, to be sure tuning will not interfere with others who may already be using the frequency.
• When the optimum tuning point has been achieved, the transceiver will return to receive.
• It is normal to hear the sound of the relays while tuning is in progress.

FTX-1 Field does not include a built-in antenna tuner. When automatic antenna tuning is required, connect an optional external tuner such as the FC-40 or the FC-80. Remember that whenever an external antenna tuner is connected to the antenna connector, the built-in ATU of the FTX-1 optima must not be used.

For additional details on the following Functions, refer to the Advanced Manual which may be downloaded from the Yaesu website.

You can change each of the high, mid, and low frequencies of the received audio to your liking. It can be set for each mode.
