INTRODUCTION
THANK YOU!
The TS-8708S Intelligent Digital Enhanced Communications
System was developed by a team of engineers
determined to continue the tradition of excellence and
innovation in KENWOOD HF transceivers.
Taking maximum advantage of Digital Signal
Processing technology, the TS-870S introduces
operating tools like Auto Notch, Beat Cancel, and Noise
Reducer. When coupled with its IF Shift, Noise Blanker,
and Advanced Intercept Point functions, you will enjoy a
critical edge as you fight QRM and QRN in the new
solar cycle. In addition, the convenience of a built-in
RS-232C connector can transport your shack into the
world of remote transceiver control via computer.
But first, tame your ego and enthusiasm temporarily —
read every page of this book. Consider this manual to
be a personal tutorial from the designers; aliow it to
guide you through the learning process now, then act as
a reference in the coming years. Though user friendly,
the TS-8708 is technically sophisticated and some
features may be new to you. Your reward for your
diligence will be mastery of the TS-870S in the shortest
time possible with maximum fun.
As you continue exploring Amateur radio, thank you for
allowing the KENWOCD family to join you in this
chapter of your adventure.
DSP —
MAXIMUM SIGNAL/ MINIMUM NOISE
The TS-870S design includes a 2-channel Sigma-delta
A/D converter, two 2-channel Sigma-deita D/A
converters, and a 2-channe! advanced single-bit D/A
converter. Operating at a clock rate of 40 MHz, DSP
works for you whether you use SSB, CW, FM, or any
other mode. The adaptive filter functions include Auto
Notch, Line Enhance, and Beat Cancel.
DSP is the most effective way of using current
technology to separate what you want from what you
don't want. While receiving, you hear the most signal
and the least noise. While transmitting, you emit only
the desired audio components of the modulation without
adding distortion. The transmit equalizer combines high
boost, bass boost, and comb filter functions to further
improve your signal.
With DSP, you will hear clear receive signals that are
covered by noise on conventional equipment. The
enhancement of the receive signal is due to the
reduction of atmospheric and white noise, and to
rejection of adjacent frequency interference including
heterodynes. This capability of DSP to "clean up" the
environment surrounding the desired signal has a
significant effect. The signal you are trying to receive
will seem stronger and clearer even though the S-meter
reads the same. Those tired of listening to interference
of all kinds while operating may think a little magic is
being used.
FEATURES
+
Employs Digital Signal Processing (DSP) techniques
to significantly improve the quality of received and
transmitted signals.
+
Includes extensive user-adjustable digital and analog
filtering functions for combating all forms of received
interference.
-
Allows total customization of transmitted audio
through use of functions such as Transmit Equalizer.
»
Introduces a built-in RS-232C port for directly
interfacing to a computer. Supports computer
control of functions at a user-selectable transfer rate
between 1200 and 57600 bps inclusive.
«
Streamlines function setup by presenting an intuitive
Menu System for function configuration and control.
+
Conveniently allows ANTENNA1/ANTENNA2
selection from the Front Panel.
*
Directly addresses CW operators' interests by
including a full-function K-1 Lagikey complete with
test made, semi-automatic mode, and popular keyer
emulations. The Rear Panel is equipped with a
PADDLE jack and a KEY jack for connecting a
paddle, an external keyer, or a keyboard.
*
Pravides an antenna tuner that can easily be
inserted into or removed from the transmit and
receive paths.
