FT-847 OPERATING MANUAL
TRANSMITTING
OPERATION
POWER OUTPUT/ALC LEVEL MONITORING
During transmission, you have the option of monitor-
ing RF power output (“PO” on the Meter) or relative
ALC voltage (“ALC” on the Meter). The default set-
ting for the Meter is PO, and the selection may be
switched to ALC via Menu #24. For initial setup, we
recommend that you make this change now, then re-
turn the setting to PO, if you like, once initial adjust-
ments have been completed.
To do this:
Press the [MENU] switch momentarily to activate
the Menu mode.
Now rotate the SUB-TUNE control until Menu #24
(“
TX MTR
”) appears.
ƒ
If the current value is shown to be “
PO
,” rotate the
MEM/VFO CH control so that “
ALC
” appears on
the display.
Now press the [MENU] switch once more to lock
in your new setting and exit the Menu mode. Now
proceed to the “SSB TRANSMISSION” section on the
next page.
See page 82 for a complete description of Menu op-
eration.
Now that you are familiar with basic receiver opera-
tion, we shall explore the FT-847’s capabilities in the
transmit mode.
The transmitter can be activated within any of the 500-
kHz segments (detailed below) which contain the HF
amateur bands, as well as 50-54 MHz, 144-146 (or
144-148) MHz, and 430-440 (or 450) MHz. When
tuned to any other frequency, the transmitter will be
disabled. Within the 500 kHz HF transmitting seg-
ments, you (the control operator) are responsible for
restricting your transmissions to those frequency sub-
bands on which you are authorized to operate. Attempt-
ing to transmit outside an amateur band segment will
cause the “ERROR” diagnostic message to appear on
the display.
Important Note!
Whenever you transmit, be certain to have a
suitable antenna or 50 dummy load connected
to the antenna jack in use. Although the final
amplifier stage of this transceiver includes pro-
tection circuitry which will immediately reduce
power if no load is present, there still is a slight
chance of damage to your equipment in the (un-
likely) event of a catastrophic protection-cir-
cuitry failure.
Remember that there are four antenna jacks on
the rear panel of the FT-847, and each should
be connected to an antenna or dummy load in
the interest of long-term safety and reliability.
