Hz), 1, 3 and 5 KHz. If you are operating in ham bands (and
especially when using CW), the 100 Hz (.1 KHz) mode is
best. On the short wave broadcast bands, scanning at 5 KHz
is great!
The Scan button engages the automatic scanning functions of
the SG-2000. The scanning function operates in three
different modes; scanning by frequency, scanning by channel,
and scanning by scan bank. Scanning may also be controlled
by an external device such as a computer or ALE controller.
When operated by an ALE controller the SG-2000 will scan at
speeds in excess of 5 channels per second. Manual operation
is variable from 5 seconds per channel to approximately 5
channels per second.
In the frequency mode, the SG-2000 will scan up or down in
discrete steps defined by the Step Function. By rotating the
Spinner Knob clockwise or counterclockwise, the direction of
the scan can be changed to direct the scan to the desired
frequency range. If the squelch is activated in scan, the unit
will continue scanning until activity breaks the squelch. The
unit will then pause for 5 seconds and if there are no more
breaks in the squelch, the unit will continue in the original
direction.
The scan channel mode is similar to the frequency mode in
that when activated, the unit will begin to scan factory
programmed ITU-VOICE and ITU-SITOR channels.
direction of the scan can be changed rotating the Spinner
Knob clockwise or counterclockwise.
Spinner Knob in scan, the unit will step once in that direction
and then pause for approximately 2 seconds. This will allow
the manual stepping through of the scan routine to find
activity. The ITU or SITOR channels can be selected by first
setting the radio in VOC or TELEX modes respectively.
The programmed scan mode allows you to program
channels into one of six banks or files for scanning. There are
six banks with up to 10 files in each, allowing up to 60
channels to be programmed. When scanning, the unit will
search through the selected banks at a pre-determined rate.
This scan rate may be changed at any time using the RATE.
