INTRODUCTION

THANK YOU!

The TS-870S 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; allow it to

guide you through the learning process now, then act as

a reference in the coming years. Though user friendly,

the TS-870S 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 KENWOOD 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-delta D/A

converters, and a 2-channel 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 Logikey complete with

test mode, 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.

•Provides an antenna tuner that can easily be

inserted into or removed from the transmit and

receive paths.

SUPPLIED ACCESSORIES

You can effectively

lengthen the front feet of

the TS-870S. Remove the

screws that fasten the front

feet to the transceiver. As

shown, install the supplied

spacers and the front feet

by using the supplied

screws. The removed

screws are not required,

but save them in case you

decide to remove the

spacers in future.

These sides

must face the

TS-870S case.
