Chapter 10 Scan; Program Scan; Scan Hold; Confirming Start/End Limits - Kenwood TS-870S Instruction Manual

SCAN
Scan is a useful feature for hands-off monitoring of your
favorite frequencies. After becoming comfortable with
how to use all types of Scan, the monitoring flexibility
gained will increase your operating efficiency.
This transceiver provides the following types of Scan:
Scan Type

Program Scan

All-channel
Scan
Memory
Scan
Group Scan
PROGRAM SCAN
The Program Scan function scans the range between
the Start frequency and End frequency stored in
memory channel 99. If Program Scan is used before
you store a Start and an End frequency, then the lower
and upper frequency limits of the transceiver are
automatically stored for the Start and End frequencies
respectively. Some General market versions substitute
the lower and upper frequencies for the current band in
place of the frequency limits of the transceiver.
Program Scan direction is controlled by the Start and
End frequency relationship. The following table
summarizes the way that Program Scan functions:

Purpose
General update of activity
on the entire band or a
sub-section of the band
while in VFO mode.
Quick activity update of all
programmed Conventional
memory channels.
Quick activity update of a
selected group of
Conventional memory
channels.
Program Scan
Action
Up
Jumps to Start
frequency, then
scans up.
Monitors
Start/End
frequency.
Jumps to
Start/End
frequency and
monitors it.
Down
Jumps to Start
frequency, then
scans down.
For a refresher on how to store the Program Scan
Limits, refer to "STORING SCAN LIMITS IN CH 99"
{page 58}. The following are additional important points
regarding the Program Scan function:
• Starting a transmission by closing the CW key, by
sending a packet, or by triggering the VOX circuit by
voice or the DRU-3 Digital Recording Unit stops
Program Scan; however, transmission does not
begin immediately.
• When the Program Scan range is smaller than a
single step of the M.CH/VFO.CH control, turning this
control causes Scan to jump to the lower of the
Start/End frequencies, then continue scanning.
• Starting the Program Scan function switches OFF
the RIT and XIT functions. RIT and XIT are not
switched ON again when Program Scan stops, and
the RIT/XIT offset frequency is not cleared.
• Operating mode can be changed while scanning.
• If Automatic Mode is switched ON, it will function
with the Program Scan function.
Use the following procedure to activate Program Scan.
1 Select the VFO mode using VFO A or VFO B.
2 Press [SCAN].
3 To stop scanning, press [SCAN], or [CLR], or
[SEND], or Mic [PTT].

SCAN HOLD

While using Program Scan, if Menu No. 65
(PG.S.HOLD) is switched ON, then turning the Tuning
or M.CH/VFO.CH control stops the transceiver from
scanning for approximately five seconds. This is also
true if Mic [UP] or [DWN] is pressed. Program Scan
resumes after the five second pause. The default is
OFF.

CONFIRMING START/END LIMITS

1 Recall memory channel 99.
2 Press [DOWN] to check the Start frequency and
press [UP] to check the End frequency.
