Speech Processor; Rf Power Output Control - Yaesu FTDX101MP Operation Manual

Speech Processor

The FTDX101 Speech Processor is designed to
increase "talk power" by increasing the average
power output of the transmitted SSB signal.
The speech processor function only works in
SSB mode.
It does not work in other modes.
1. Press the [FUNC] key.
2. S e l e c t [ O P E R A T I O N S E T T I N G ] →
[TX AUDIO] → [PROC LEVEL].
3. Select [COMP].
4. Press the [FUNC] key to save the new set-
ting and exit the Setting Menu.
5. Press the [FUNC] key to exit to normal
operation.
6. Adjust the MIC gain, as described in Para-
metric Microphone Equalizer on Parametric
Microphone Equalizer (page 52).
7. Touch the left meter area on the display to se-
lect the "COMP" meter.
The transmit meter becomes the "COMP"
meter.
8. Press the [MIC/SPEED] knob.
While the Speech Processor function is ac-
tive, the indicator on the left side of the [MIC/
SPEED] knob will light.
9. Press the PTT switch on the microphone, and
speak into the microphone in a normal voice
level.
10. Adjust the [PROC/PITCH] knob to set the
compression level within 10 dB.
● The Transmit Monitor is a helpful aid to ver-
ify proper adjustment of the Compression
level.
To switch the Speech Processor OFF, press the
[MIC/SPEED] knob once more.
The speech processor can distort the transmit
waveform when used to increase the average
TX power, so it is not used in normal communi-
cation.

RF Power output control

Turn the [MULTI] knob to adjust the RF power
output.
1. Press the [FUNC] key.
2. Touch [RF POWER].
3. Rotate the [MULTI] knob to adjust the RF
power.
When transmitting in the AM mode, set a max-
imum (carrier) power output of 50 Watts (for
FTDX101MP) or 25 Watts (for FTDX101D).
● Setting of maximum transmission output
The maximum transmit power can be set for each
of the HF Bands, the 50 MHz band and the AM
mode.
Set according to the operation situation, when
you do not need large transmission output.
1. Press the [FUNC] key.
2. Select [OPERATION SETTING] → [TX GEN-
ERAL].
3. Rotate the [MULTI] Knob to select the item
you want to set.
HF MAX POWER (HF band)

AM MAX POWER (AM mode)
(The setting range is 5 to 50 W*
1
* FTDX101D is 100 W
