You may scan wither the VFO or the memories of the FT
DX
9000D, and the radio will halt the scan on any station with a
signal strong enough to open the receiver’s squelch.
VFO S
CANNING
1. Press the A or B switch (# ) to select the VFO
to be scanned.
2. Set the VFO to the frequency on which you would
like to begin scanning.
3. Rotate the SQL control (# for Main (VFO-A)
band scan, # for Sub (VFO-B) band scan) so that
the background noise is just silenced.
4. Press and hold in the microphone’s UP or DOWN
key for 2 second to start scanning in the specified di-
rection.
H
If the scanner halts on an incoming signal, the decimal point
between the “MHz” and “kHz” digits of the frequency dis-
play will blink.
H
If the incoming signal disappears, scanning will resume in
about five seconds.
H
On the SSB/CW and SSB-based Data modes, the scanner will
pause on a received signal, then will step across the signal
very slowly, giving you time to stop the scan, if you like. In
these modes on the VFO, the scanner does not stop, however.

Quick Point
If you have no interest in scanning, and wish to prohibit
the microphone’s UP / DOWN keys from initiating
scanning, you may disable scanning control from the mi-
crophone using Menu Item “GENERAL 036 MIC SCAN”
(set it to “DISABLE”).

1. Set the transceiver up in the memory mode by press-
ing the V/M key, if necessary.
2. Rotate the Main (VFO-A) receiver’s SQL control
(#
) so that the background noise is just silenced.
3. Press and hold in the microphone’s UP or DOWN
key for 2 second to start scanning in the specified di-
rection.

If the scanner halts on an incoming signal, the decimal point
between the “MHz” and “kHz” digits of the frequency dis-
play will blink.

If the incoming signal disappears, scanning will resume in
about five seconds.
Advice
During Memory Group operation, only the channels
within the current Memory Group will be scanned.
If the scan has paused on a signal, pressing the
microphone’s UP or DOWN key will cause scan-
ning to resume instantly.
If you press the microphone’s PTT switch during scan-
ning, the scanner will halt at once. Pressing the PTT
switch during scanning will not cause transmission,
however.
You may select the manner in which the scanner re-
sumes while it has paused on a signal, using Menu
item “GENERAL 037 MIC SCAN RESUME.” Dur-
ing memory scanning, the default “TIME” setting will
cause the scanner to resume scanning after five sec-
onds; you may change it, however, to resume only af-
ter the carrier has dropped out, if you like See page
134.
