FT-847 OPERATING MANUAL
OPERATION
…
You also can adjust the sidetone pitch using Menu
#6. This adjustment also controls the BFO offset
(the actual pitch of your transmitted signal relative
to your current receive frequency).
To adjust the CW pitch:
l Press the [MENU] button to activate the Menu
mode of operation.
l Rotate the SUB-TUNE knob to select Menu #6
(“
CW-PITCH
”).
l Rotate the MEM/VFO CH knob to select a new
pitch tone/BFO offset.
l The available offset range is 400 ~ 1100 Hz.
l Press the [MENU] key to exit the Menu mode.
The setting of Menu #6 also affects the “CW SPOT”
function. See the “CW SPOT FEATURE” discussion
below for details.
†
You may also adjust the receiver recovery time of
the pseudo-VOX system which automatically acti-
vates the transmitter when you close the key. The
default value for this feature is 100 ms.
To adjust the “hang time” for CW operation:
l Press the [MENU] button to activate the Menu
mode of operation.
l Rotate the SUB-TUNE knob to select Menu #9
(“
CW-DELAY
”).
l Rotate the MEM/VFO CH knob to select a new
delay time. The available range of adjustment
is 10 ~ 300 ms.
l Press the [MENU] key to exit the Menu mode.
Although the FT-847 was not designed for “full
QSK” operation, the minimum setting of Menu #9
(10 ms) will be very close to full break-in perfor-
mance.
‡
If you are using an external electronic keyer, and it
provides a “PTT” line for transceiver TX/RX con-
trol, this line may be connected to the rear-panel
PTT jack.

Note
Regarding CW Frequency Display
The FT-847’s frequency display is specifically
designed to provide you with precise indication
as to the zero beat frequency of your CW car-
rier, so you always know where your signal is
relative to the band edges.
Accordingly, the displayed frequency on CW
will be different from that displayed on the cor-
responding SSB mode by an amount equal to
the setting of the PITCH command (Menu #6).
For example, if Menu #06 is set to 700 Hz, and
you are operating on 144.200 MHz USB, if you
switch to CW (USB side) the display will now
indicate 144.200.700 MHz, but the pitch of in-
coming signals will not change. Conversely, if
you are operating on 3.790 MHz LSB, and
switch to CW (LSB side), the display will now
indicate 3.789.300 MHz, but signals received
will be on the same pitch as they were on the
(voice) LSB mode.
