SCANNING OPERATION
SCANNING FEATURES
Scan-Resume Choices
Scanning operation requires that you have the FT-897D’s
audio squelched. The transceiver then “assumes” that the
opening of the squelch corresponds to the discovery of a
signal you may wish to listen to.
Once the scan has been halted, one of three things may hap-
pen:
TIME (default action): In this mode, the transceiver pauses
on the signal and stays locked on its frequency for
five seconds. Thereafter, scanning will resume
whether or not the other station’s transmission has
ended. The pause time is adjustable from 1 to 10 sec-
onds via Menu Mode No-078
[
SCAN RESUME
]
.
BUSY:In this mode, the scanner will halt until the other
station’s transmission ceases (at which point the
squelch will close). One second after the squelch
closes, scanning resumes automatically.
STOP:In this mode, the scanner will find a signal, and lock
on that frequency without resuming the scan.
To choose the Scan-Resume mode:
1. Press and hold in the
[
F
]
button for one second to acti-
vate the Menu mode.
2. Rotate the MEM/VFO CH knob to select Menu Mode
No-077
[
SCAN MODE
]
.
3. Rotate the DIAL knob to select the desired Scan-Resume
mode.
4. Press and hold in the
[
F
]
button for one second to exit
the Menu mode.
This transceiver contains a wide variety of scanning capa-
bilities. Whether you are in the VFO mode or one of the
memory modes, scanning operation is fundamentally iden-
tical in all configurations, but with the following differences:
In the VFO mode, scanning causes the transceiver to
sweep up or down the band, pausing or halting on any
signal encountered;
In the Memory mode, the scanner will scan the pro-
grammed memories, and can be instructed to skip cer-
tain memories during scanning;
In the Programmable Memory Scan (PMS) mode, the
scanner will scan the band within user-programmed fre-
quency limits.
Scanning Operation
In order for the FT-897D to scan automatically, the Squelch
must be set so that the background noise is silenced, be-
cause the command to “Stop Scanning” driven by the same
circuit that causes the green “Busy” LED to light up (when
noise or a signal is received).
1. Set the SQL knob to the point where background noise
is silenced. A typical setting, for effective scanning op-
eration, will be at 12 o’clock or slightly clockwise from
this position.
2. Set the transceiver into the operating configuration in
which you wish to scan (VFO or Memory; PMS will be
described later).
3. Press the
[
F
]
key momentarily, then rotate the MEM/
VFO CH knob, as needed, until Multi Function Row
“g”
[
SCN, PRI, DW
]
appears on the display.
4. Press the
[
A
](
SCN
)
key momentarily to start upward scan
(toward higher frequencies or higher memory channel
numbers).
5. Rotate the DIAL knob or MEM/VFO CH knob counter-
clockwise to toggle the scanning direction downward.
6. The scanner will now cause the transceiver to increment
in the chosen direction until a signal is detected. When a
signal is encountered which opens the Squelch, it will
do different things, depending on the operating mode:
In the FM/AM modes, the transceiver pauses on the
signal and stays locked on its frequency for five sec-
onds. Thereafter, scanning will resume whether or
not the other station’s transmission has ended. While
the transceiver is in the “Pause” condition, the deci-
mal points in the frequency display area will blink.
See “Scan-Resume Choices” on next chapter for de-
tails of how to customize the resumption of scanning.
In the SSB/CW modes, the scanner will slow down
(but wonn’t stop).
7.
Press the PTT switch on the microphone to cancel scanning.
You may also press and hold in either the [UP]
or [DWN] key on the microphone for one sec-
ond to initiate upward or downward scanning,
respectively, if Menu Mode No-058 [MIC SCAN] is set to
“ON.”
