SAVE THIS INSTRUCTION MANUAL.
The following explicit definitions apply in this
manual:
Note : If disregarded, inconvenience only, no
risk of equipment damage or personal
injury.
Caution : Equipment damage may occur, but not
personal injury.
i This Instruction Manual covers the following
! models:
TS-950SDX: HF TRANSCEIVER with the , SO-2, YK-
880-1, YG-455C-1, and YG-455S-1,
are included in this transceiver as
standard equipment.
FCC WARNING
This equipment may generate or use radio
frequency energy. Changes or modifications to
this equipment may cause harmful interference
unless the modifications are expressly approved
in the instruction manual. The user could lose the
authority to operate this equipment if an
unauthorized change or modification is made.
i Note
This equipment has been tested and found to
comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection
against harmful interference in a_ residential
installation. This equipment may cause harmful
interference to radio communications, if it is not
installed and used in accordance with the
instructions. However, there is no guarantee that
interference will not occur in a particular
installation. if this equipment does cause harmful
interference to radio or television reception,
which can be determined by turning the
equipment off and on, the user is encouraged to
try to correct the interference by one or more of
the following measures:
=- Reorient or relocate the receiving antenna.
= Increase the separation between the
equipment and receiver.
ie Connect the equipment into an outlet on a
circuit different from that to which the
receiver is connected.
~~ Consult the dealer or an experienced
tadio/TV technician for help.

7. Enclosure removal — Never remove the en-
closure. If the internal parts are toucned ac-
cidentally, a serious electric sheck might occur.
8. Water and moisture - The unit should not be
used near water for example, near a bathtub,
washoowl, kitchen sink, laundry tub, in a wet base-
ment, or near a swimming pool, ete.
9. Outdoor antenna grounding — If an outside an-
tenna is connected to the receiver, be sure the an-
tenna systern is grounded so as to pravide some
protection against voltage surges and built up static
charges. Section 810 of the National Electrical
Code, ANSI/NFPA 70, orovides information with
respect to proper grounding of ihe mast and sup-
porting structure, grounding of the lead-in wire ta
an antenna discharge unit, size of grounding con-
ductors, location of antenna-discharge unit, con-
nection to grounding electrodes, and requirements
for the grounding siectrode. See the accompany-
ing illustration.

(1) Antenna
Caution
Protect your equipment --- Use a LIGHTNING
ARRESTER.
The type of antenna that is used will greatly affect
the performance of the transceiver. Use a properly
adjusted antenna, of good quality, to enable your
transceiver to perform at its best. The antenna input
impedance is 50 ohms. Use 50-ohm coaxial cable
such as RG-8 or 5D-2V for this connection. If the
antenna is far from the transceiver the use of low
loss coaxial cable, such as 10D-2V is recommended.
Match the impedance of the coaxial cable and that
of the antenna so that the SWR is less than 1.5 to 1.
The protection circuit in the transceiver will activate
if the SWR is particularly poor (greater than 3 to 1).
A high SWR value will cause transmitter output to
drop, and may lead to TVI or BCI reports.
(2) Grounding
Caution
Never use a gas pipe or electrical conduit pipe for
ground connection.
Notes
1. A ground connection that is a 1/4 wavelength or
its multiple may provide a good DC ground, but
it will not provide a good RF ground.
2. A city. water pipe cannot be used as a good į
earth in some cases. |
j
Making a good earth connection is important for
preventing dangers such as electric shock and for
emitting a high quality signal with minimum
spurious radiation. Bury a commercially available
ground rod or copper plate under the ground and
connect it to the GND terminal. A thick wire, cut as
short as possible, should be used for the connection.
To make a good earth connection, connect the GND
terminal to a grounded metal water pipe.
(3) External speaker
The TS-950SDX includes a built-in speaker. If you
would like to use an external speaker, such as the SP-
950, it may be connected to the EXT SP jack on the
rear of the radio. The speaker may be any good 8
ohm permanent magnet type speaker. The diameter
should be at least 4 inches for good audio quality. If
you plan on using a speaker other than the SP-950, it
should be equipped with a miniature phone jack
plug. (diameter 3.5 mm}
E External Speaker and Voice Outputs
Using an external speaker, you can switch the MAIN
and SUB voice outputs.
To switch the voice outputs, use the MENU key as
follows:
MENU operation
1. Press the MENU key.
2. Adjust the M.CH/VFO CH control to select menu
number 06. The SUB frequency display will then
show the current setting.
3. Use the UP/DWN switches to select the desired
function.
4, Press the MENU key again to complete this MENU
operation.

Headphone
Microphone
(1) Headphones
Any low-impedance (4-16 ohms) headphones may
be used with the transceiver. Connect the
headphones to the front panel PHONES jack.
(diameter 6.0 mm). The optional HS-5 or HS-6
headphones are best suited for use with the
transceiver. Stereo. type headphones can also be
used. When using Stereo headphone the main band
will be heard on one side and the sub-band on the
other side. If the sub-band is turned off no audio will
be heard on the sub-band side.
(2) Microphones
Any microphone with an impedance between 250 Q
to 600 Q may be used with this transceiver. The
KENWOOD microphones MC-43S (handheld), MC-
60A, MC-80, MC-85, MC-90 {table-top type) are
recommended.

@ POWER switch
Press to turn the power ON or OFF.
@ ATT (Attenuator) switch
When the incoming receive signal is very strong,
the signal should be attenuated to prevent
distortion of the signal, thereby stabilizing the
receiver performance. This is easily done by
activating the ATT switch. This control is also useful
when a strong signal is near your desired signal;
while some loss will occur to the desired signal, as
well as the undesired signal, the use of the
attenuator will sometimes allow you to understand
what is being received. This switch allows
attenuation of the input signal by 6, 12 or 18 dB.
For normal receiver performance, this switch
should be in the 0 dB position.
10
@ VOX/MAN switch
VOX (Voice Operated Switch} operation is possible
in SSB, AM or FM operations. Break-in operation is
possible in CW operation. To activate the VOX
circuitry place the VOX switch ON (mm).
@ FULL/SEMI (Break-in) switch
This switch affects the transmit/ receive recovery
time. In the SEMI position the transceiver will key
when the key is depressed and remain in the
transmit position until a preset delay has been
reached. In the FULL position the transceiver will
switch back to receive as soon as the key is released,
thus allowing you to copy incoming signals
between characters.
© MONI (Monitor) switch
Allows monitoring of your transmit signal.
© DIM (Dimmer) switch
Selects the intensity of both the digital display and
the meter illumination, bright or dim.
