FT-847 OPERATING MANUAL
(19) FAST Switch
Pressing this switch toggles the transceiver between
“high speed” and “slow speed” tuning rates for the
MAIN VFO Tuning Dial, the SUB-TUNE knob, the
MEM/VFO CH knob, and the UP/DOWN switches.
The “
FAST
” icon will appear on the display panel when
the fast-tuning mode has been selected.
(20) MAIN VFO Tuning Dial
This large knob is the main tuning dial for the trans-
ceiver, controlling the frequency of the Main VFO.
Clockwise rotation of the dial increases the frequency,
while counter-clockwise rotation of the dial decreases
the frequency.
The tuning steps may be changed via the Menu sys-
tem. The default tuning steps are shown below:
(21) SHUTTLE JOG
™
Control
The outer “SHUTTLE JOG™” control is concentric
to and slightly behind the MAIN VFO Tuning Dial.
The SHUTTLE JOG™ allows fine or rapid frequency
excursions with just a slight turn of your hand. Rotat-
ing this control slightly to the left or right initiates slow
tuning in a downward or upward direction, respec-
tively. The more you rotate this spring-loaded control,
the faster the Main VFO frequency will be changed.
(22) LOCK Switch
This switch locks the settings of the MAIN VFO Tun-
ing Dial, SHUTTLE JOG™ ring, and the SUB-
TUNE knob. Other front panel switches may also be
locked out, using Menu #27 (see page 87).
(23) SATELLITE Mode Indicators
These indicators provide satellite operating mode in-
formation, and they become illuminated based on mode
selections made via the switches immediately below
the indicators (see sections (24) ~ (27) below for de-
tails).
[RX] (HOME)
In this mode, the MAIN VFO Tuning Dial is
used to control the downlink (receive) frequency
during satellite operation.
[TX] (VFO/M)
In this mode, the MAIN VFO Tuning Dial is
used to control the uplink (transmit) frequency
during satellite operation.
[TRACK] (AuB)
In this mode, the Main and Sub VFOs are
“slaved” so that they change frequency together
when the MAIN VFO Tuning Dial is rotated. In
the “TRACK” mode, either “normal” or “inverted”
transponders may be utilized, depending on the
selection made by the [N/R] switch (see below).
[N/R] (SPLIT)
This switch selects the transponder operating
mode during satellite operation. In the “N” (Nor-
mal) mode, increasing the Main VFO frequency
also causes an identical increase in the Sub VFO
frequency.
In the “R” (Reverse) mode, increasing the Main
VFO frequency causes an identical decrease in
the Sub VFO frequency.
(24) HOME [RX] Switch
This switch is used to recall the “HOME” memory chan-
nel on each band.
In the SATELLITE mode, pressing this switch causes the
Main VFO to be designated as the Receive (downlink)
VFO; in this case, the Transmit (uplink) frequency will
be controlled by the SUB-TUNE knob.
(25) VFO/M [TX] Switch
Pressing this switch changes frequency control be-
tween the Main VFO and the Memory systems. Re-
peatedly pressing this switch causes frequency con-
trol to toggle between these two systems.
In the SATELLITE mode, pressing this switch causes the
Main VFO to be designated as the Transmit (uplink)
VFO; in this case, the Receive (downlink) frequency
will be controlled by the SUB-TUNE knob.
(26) A
u
B [TRACK] Switch
Pressing and holding in this switch for ½ second causes
the contents of the Main VFO to be copied into the
Sub VFO, so that the two VFOs’ contents will be iden-
tical.
In the SATELLITE mode, pressing this switch activates
the “VFO Tracking” mode, whereby the Main VFO
and Sub VFO are “slaved” under control by the MAIN
VFO Tuning Dial.
