82 FT-857D Operating Manual
SCANNING FEATURES
This transceiver contains a wide variety of scanning capabilities. Whether you are in the
VFO mode or one of the memory modes, scanning operation is fundamentally identical in
all configurations, but with the following differences:
In the VFO mode, scanning causes the transceiver to sweep up or down the band, paus-
ing or halting on any signal encountered;
In the Memory mode, the scanner will scan the programmed memories, and can be
instructed to skip certain memories during scanning;
In the Programmable Memory Scan (PMS) mode, the scanner will scan the band within
user-programmed frequency limits.
SCANNING OPERATION
In order for the FT-857 to scan automatically, the Squelch must be set so that the back-
ground noise is silenced, because 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 operation, 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
[
FUNC
]
key momentarily, then rotate the SELECT knob, as needed, until
Multi Function Row “g”
[
SCN, PRI, DW
]
appears on the display.
4. Wait at least five seconds, until the “MFg” notation disappears, then press the
[
A
](
SCN
)
key momentarily to start upward scan (toward higher frequencies or higher memory
channel numbers).
5. Rotate the DIAL knob or SELECT knob counterclockwise to toggle the scanning di-
rection 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 seconds. Thereafter, scanning will resume whether or not the other
station’s transmission has ended. While the transceiver is in the “Pause” condition,
the decimal points in the frequency display area will blink. See “Scan-Resume Choices”
in the next chapter for details of how to customize the resumption of scanning.
In the SSB/CW modes, the scanner will slow down (but won’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 second to initiate upward or downward scanning, respectively, if Menu
Mode No-058 [MIC SCAN] is set to “ON.”
