Busy-Frequency Stop; Scan Speed Change - Kenwood TS-50S Instruction Manual

BUSY-FREQUENCY STOP
When a signal is received during memory or program
scan, the transceiver automatically stops scan and
remains on that frequency for either a short time (Time
Operated mode), or remains until the signal drops
(Carrier Operated mode). The Squelch must be
adjusted to the noise threshold paint when there is no
signal.
In the Time Operated mode, scan stops on a busy
frequency for approximately six seconds, and then
resumes.
In the Carrier Operated mode, scan stops on a busy
frequency while a Signal is present, and resumes
approximately two seconds after the signal drops.
Select the stop mode using the Menu Set-up function.
Menu A, No. 10 is for program scan, and Menu A, No.
12 is for memory scan (refer to page 46.) Time
Operated mode is the factory default.
Note:
For
scan
to stop, the Squelch control must be set
to
just
beyond the threshold (where the background noise just
disappears when no
signal
is present).
The Busy-Frequency Stop function can be turned on
or off. Refer to Menu Set-up on page 46. Menu A,
No. 09 is for program scan, and Menu A, No. 11 is for
memory scan.
SCAN SPEED CHANGE
The scan speed can be varied from the default fastest
rate using the RIT control. A weight value appears on
the display right during scan that acts as a speed
reference number. Turning the RIT control clockwise
decreases the scan speed, and counterclockwise
increases the speed.

SCAN As this number
increases, the scan
speed slows.
5 SCAN
When using the 500 Hz filter or listening for
particularly weak signals, use a slower scan speed to
ensure scan stops on all Signals.
The scan step size, and therefore the scan speed,
varies according to whether Busy-Frequency Stop is
on or
off,
and which modulation mode is selected as
follows:
I
Busy-Frequency
Stop OFF

SSB/cwi FM/AM

I
"5 kHz
• Except in the Broadcast Band: 9 kHz steps when 9
kHz is selected via Menu B, No. 61. Refer to Menu
Set-up on page 47.
Turning the RIT control counterclockwise decreases
the weight value (faster scan speed) whereas turning it
clockwise increases the weight value (slower scan
speed). Any value selected remains in effect until you
adjust the control again, or until you reset the
transceiver using the A=B key.
Remember to center the RIT control once finished
scanning to avoid confusion later when the RIT is
used.
