3 REC/SEND switch
This switch is used when you want to manually
control transmission or receiving.
REC : Places the radio into the receive mode.
SEND : Places the radio into the transmit mode.

THRU: The auto antenna tuner is not used in the
transmit mode.
AUTO: The auto antenna tuner is used in the
transmit mode.
FF/AT TUNE switch
When this switch is turned ON with the
THRU/AUTO, switch placed in the AUTO position,
the automatic tuner will be engaged and the tuner
will try to match the antenna.
36 PHONES jack
Output terminal for headphones.
MIC jack
Microphone connection.
GND (STBY) #
MIC connector (Front view)
@® KEY SPEED control
This controls the speed of the electronic keyer. Turn
the knob clockwise to increase speed.
® AGC switch
This switch selects the operating time constant of
the AGC (Automatic Gain Control) circuit. When
the AGC switch is set to AUTO the gain is
automatically controlled for the selected mode.
When the AGC switch is set to SLOW, the receiver gain
and S-meter readings will react slowly to large input
changes, and when set to FAST, the receiver gain and
S-meter will react quickly to changes in the input signal
tevel.
The normal position when using all modes is the
SLOW position. When working any of the
following, you might wish to use the FAST position.
® When tuning rapidly, use the FAST position.
@ When receiving weak signals.
@ When a high-speed CW signal is being received.
| Note
This switch is disabled during FM operations.
40; MAIN NB LEVEL control

Use only the minimum level necessary.
© SUB NB LEVEL control

& NB 1 switch
For pulse type noise, such as generated by
automotive ignition systems, turn the NB 1 switch
ON.
This switch will not heip 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
tone 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-950SDX
are effective in most cases.
If there is no woodpecker" present, the switch should
be in the OFF position.
