Kenwood TS-850S - Manual (Page 12)

(i|) RIT/XIT frequency display
Shows the amount of RIT/XIT offset to the nearest
10 Hz. Minus “ —” appears in the display when the
RIT / XIT offset is below the transmit / receive
frequency.
Shows the scan speed during scanning.
Note
This switch is disabled during FM operation.
@ NOTCH control
The NOTCH function is used to reduce or eliminate
heterodyne, or CW type signals. The NOTCH filter
will not be effective against SSB, AM or FM type
signals.
@ SQL (Squelch) control
This control is used to eliminate atmospheric noise,
and receiver static noise during no signal periods.
Slowly rotate the control clockwise to the point
where the ambient noise just disappears, and the
speaker shuts off. This point is known as the
squelch threshold point. Now you will only hear
output from the speaker when an incoming signal is
present. For weak signal reception this control
should be fully counterclockwise.
@ NB LEVEL control
Controls the noise blanker operating level.
Use only the minimum level necessary.
(§) NB2 WIDTH control
This control varies the width of the blanking pulse of
NB2.
Notes
1. The NB2 control only works on woodpecker
type noise.
2. If the control is turned too far, the received
signal may be distorted. Set the control for the
best receive signal.
(24) RIT switch
Press to turn the RIT ON or OFF.
@XIT switch
Press to turn the XIT ON or OFF.
@NB 1 switch
For pulse type noise, such as generated by
automotive ignition systems, turn the NB 1 switch
ON.
This switch will not help to eliminate atmospheric or
line noises, only pulse type noise.
(^ NB 2 switch
Noise blanker 2 is used for long duration pulse
noise,
like the “woodpecker”. To reduce
“woodpecker” radar noise interference, set switch
NB 2 to the ON position (NB 2’s effectiveness
depends on the specific type of interference). If you
use NB 2 for short duration pulse noise, the receive
signal may become distorted, making it difficult to
hear.
Unfortunately no noise blanker can remove all
different types of interference; but the two noise
blankers that have been provided in the TS-850 are
effective in most cases.
If there is no “woodpecker” present, the switch
should be in the OFF position.

(§) REC/SEND switch
This switch is used when you want to manually
control transmit or receive.
REC : Places the transceiver into receive.
SEND : Places the transceiver into transmit.
(§)THRU/AUTO switch
THRU : The auto antenna tuner is not used in
transmit.
AUTO: The auto antenna tuner is used in transmit.
(§) NOTCH switch
When this switch is ON, the notch filter is activated.
0 AT TUNE switch
When this switch is tuned ON and the THRU/AUTO
switch is placed in the AUTO position, the automatic
