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.

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”

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
