Clarifier; Rx Clarifier; Adjust Transmit Frequency To The Offset Frequency; Tx Clarifier - Yaesu FTDX101D Operation Manual

Clarifier

The clarifier is used to adjust the receiver frequency
of this transceiver to match the other station trans-
mit frequency and improve the audio; or to shift the
transmit frequency of this station when the transmit
frequency of the contact station is shifted.
When the [CLAR] key is pressed, the MPVD multi-
function ring becomes the Clarifier Dial and "CLAR"
is displayed in gray below the filter function display
on the TFT display.
Turning the MPVD ring changes the clarifier offset
frequency.
When the [CLAR RX] or the [CLAR TX] key is
pressed, the display changes from gray to red and
the Clarifier operates.
To turn the clarifier OFF, press the [CLAR RX] or the
[CLAR TX] key again.

• RX Clarifier

If the transmit frequency of the contact station is
deviated, this receiver frequency can be changed
leaving this transmit frequency unchanged.
1. Press the [CLAR] key on the top left of the
MPVD ring to light the indicator.
2. Press the [CLAR RX] key.
3. Rotate the MPVD ring to change only the receive
frequency.
When the receive frequency is offset by +20 Hz.
• The "CLAR RX" will appear in the display,
and the programmed offset will be applied
to the receive frequency.
• Offsets of up to ±9990 Hz may be set us-
ing the Clarifier.
4. To cancel Clarifier operation, press the [CLAR
RX] key.
● Since the offset amount is memorized, when the
clarifier function is operated again, the same off-
set amount is set.
To clear out the programmed clarifier offset alto-
gether, and reset it to "zero," press and hold the
[CLAR RX], [CLAR TX] or [CLAR] key.
• Adjust transmit frequency to the
offset frequency
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 TX] key.
The transmit frequency becomes the same as
the receive frequency.
● "CLAR RX" of the display changes to "CLAR
TRX".
2. Press the [CLAR TX] key again, only the recep-
tion frequency returns to the offset state.
● "CLAR TRX" of the display changes to "CLAR
RX".

• TX Clarifier

The transmit frequency can be changed without
moving the receive frequency of the transceiver.
Normally, the clarifier is used to move only the re-
ceive 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 fre-
quency is moved slightly.
1. Press the [CLAR] key on the top left of the
MPVD ring to light the indicator.
2. Press the [CLAR TX] key.
3. Rotate the MPVD ring to change only the trans-
mit frequency.
• The "CLAR TX" will appear in the display,
and the programmed offset will be applied
to the transmit frequency.
• Offsets of up to ±9990 Hz may be set us-
ing the Clarifier.
4. To cancel Clarifier operation, press the
[CLAR TX] key.
To clear out the programmed clarifier offset alto-
gether, and reset it to "zero", press and hold the
[CLAR RX], [CLAR TX] or [CLAR] key.
• To offset the frequency with the
TX Clarifier Adjust receive frequency
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.
After offsetting the transmit frequency, press the
[CLAR RX] key.
The "CLAR TX" display changes to "CLAR TRX"
and the receive frequency becomes the same as
the transmit frequency.
