The monitoring level may be adjusted
via Menu #20 if the monitoring level is too loud
or too soft for your operating needs. To do this,
use the following procedure:
•
Press the [MENU] button to activate the Menu
mode.
‚
Rotate the SUB-TUNE knob to select Menu #20
("MONI-VOL").
ƒ
Rotate the MEM/VFO CH knob to set a higher or
lower M volume level; you cannot transmit

while in the Menu mode, so you will need to pick
an arbitrary value at first.

Press the [MENU] button to exit the Menu mode.

Now transmit to check the M
If it still is not set to the correct level, repeat the
above procedure.
Note: The M feature is disabled on SSB during
ONITOR
Satellite operation, as it would make reception
of your own downlink signal difficult. The M
is, however, available during CW Satellite
TOR
operation, to eliminate coordination problems
in sending caused by the propagation delay to
and from the satellite.

ARRIER
Although your FT-847 is carefully aligned at the fac-
tory for the best average frequency response for most
human voices, it is possible that your voice (or your
microphone) may have particular characteristics (ex-
cessive treble or bass) which may warrant minor ad-
justments to the TX C
vided via Menu #92 (USB) and #93 (LSB), is analo-
gous to the receiver's IF S
to your own voice in the transmit mode.
Utilization of Menu items #92 and 93 requires that
you first activate the "Extended Menu" function via
Menu #42. Press the [MENU] key to enter the Menu
mode. Next, rotate the SUB-TUNE control until Menu
#42 ("EXTEND") appears. Rotate the MEM/VFO CH
control until the display changes from "OFF" to "ON."
The Extended Menu is now active; press [MENU]
again to return to normal operation.
To adjust the USB C
•
First select the USB mode, then connect a dummy
load to the current antenna jack.
‚
Switch on the V
microphone's PTT switch.
ƒ
Listen to your voice, making careful observations
as to the treble and bass characteristics.
„
Now enter the Menu mode by pressing the [MENU]
key. Rotate the SUB-TUNE control until Menu #92
("USB-CAR") is selected.
...
Rotate the MEM/VFO CH control to change the
transmit passband characteristics: rotating in the
positive direction increases the treble response,
while selecting a negative number will increase the
bass response.

so a setting of "3 " represents a passband shift of
+30 Hz.
‡
Exit the Menu mode by pressing the [MENU] key.
ˆ
Now transmit again, listening to your voice char-
acteristics. If the response is acceptable, the proce-
dure is complete. If further adjustments must be
-
ONI
made, repeat the above process.
This adjustment may also be performed for LSB via
Menu #93. The two settings need not be identical; for
example, if you use 75 and 40 meters (bands where
LSB is used) primarily for local work, you may desire
a slightly lower frequency response for a more "mel-
low" sound, while setting a slightly higher frequency
response for DX work on 20 meters and higher fre-
quency bands on the USB mode.
