FEATURES
. DCS = Digital Code Squelch
DCS uses digital code information to open squelch on
a receiver that has been programmed to accept the
specific code being transmitted. The system recog-
nizes 100,000 different 5 digit code signals, making it
possible for each station to have its own “private call”
code, as well as to have “group call” or “common call’
code. DCS is also effective in suppressing unwanted
signals.

Notes:
1. To release auto mode operation, press any key other
than the AUTO key.
2. In AUTO mode operation, frequency cannot be
changed during transmission (No. TX QSY). If the
frequency is to be changed during transmission,
such as in satellite communications, Release AUTO
mode first.
@ DIAL FREQUENCY
1. The frequency displayed is the center for carrier fre-
quency. When switching needs the display will not
shift frequency, thus the displayed frequency is the ac-
tual transmit frequency.
2. In CW operation, the displayed frequency is the trans-
mit frequency. The actual receive frequency is 800 Hz
below the transmit frequency.

1. Connect a key to the rear panel KEY jack. If the key
plug does not match the jack, use an adapter plug or
connect the supplied plug.
2. The side-tone circuit is built in, to allow monitoring your
CW signal. When in other than CW mode operation,
this is used for monitoring your CW keying practice. In
this status, transmission is inhibited.
3. Reception in CW is USB. AGC is automatically set to

@ SATELLITE COMMUNICATIONS
The present Amateur Satellites in orbit are OSCAR 10 and
RS 5 ~ 8 (USSR). Communications using these satellites
use various frequencies by transponders installed in those
satellites. When satellite communication through OSCAR
10 is to be performed using the TS-711A/E and
TS-811A/E, proceed as follows. In this operation, use
mode B. Perform the uplink on the 430 MHz band
(TS-811A/E) and the downlink on the 144 MHz band
(TS-711A/E).
OSCAR 10
Uplink frequency ............5 435.025 ~ 435.175 MHz

(USB)
General beacon freq........... 145.810 MHz
Engineering beacon freq.... 145.987 MHz

Satellite communications require advanced techniques
and skill (orbit information, use of beacon signal, use of an-
tenna, operation behavior, etc.), compared with ordinary
communications. Before transmitting, study satellite com-
munications techniques. Several publications are available
from organizations such as the ARRL and JARL.

FUNCTION CONTROLS AND SWITCHES
@® RIT
RIT (Receiver Incremental Tuning) is a function to only
shift receive frequency without changing transmit fre-
quency.
1. The RIT variable range is +9.99 kHz. The two most
significant digits are displayed.
2. The RIT allows you to obtain the exact frequency of the
other station.
3. Restoring to “0.0” (zero offset) can be done simply, by
pressing the CLEAR switch.
4. The RIT works in any mode, COM ch, M ch, or dial
locked.
5. The RIT frequency display works even with the RIT
switch OFF, and allowing you to preset the RIT.

The IF SHIFT control is used to shift the passband of the IF
filter without changing receive frequency. By turning this
control in either direction, the IF passband is shifted as
shown in above figure. The IF SHIFT is effective in elimin-
ating interference when nearby signals are supperimposed
on the receive signal during either SSB or CW operation.
IF SHIFT does not operate in FM mode.
a) To eliminate interference from signal (B), turn counter-
clockwise (-).
b) To eliminate interference from signal (A), turn clockwise
(+).

@ RF GAIN control
For normal operation, this control should be turned fully
clockwise for maximum sensitivity. Receive sensitivity is
reduced by turning the control counterclockwise. :
Adjust the RF control so the S-meter does not show ex-
cessive deflection. This minimizes noise during reception
and allows the S-meter to indicates signal peak (or a little
below that point). Noise is markedly reduced when signal
is absent.

ch and repeat steps 1 and 2.
@ Digital code standby
The “Standby” indicator is a visual indication of which di-
gital access codes will actually open the squelch of the ra-
dio. Simply stated it shows the “Active” codes. When the
indicator is on the code is active. When the indicator is
off, the code is not used.
The digital code displayed when the [CS] key is pressed
“ON” (called the transmit digital code) becomes an “active”
code regardless of the standby indicator.
However, when using the digital code standby mode, light
the standby indicator by pressing [D. SQ] key for the
transmission digital code.

Channel channel number
number
The frequency can be set with the main dial and the trans-
mission digital code channel can be set with CS switch.
@ Digital code squelch operation
The new DCS system gives the operator the ability to select
which stations he wants to listen to. Only those stations
that transmit the proper data will be able to “open” the
squelch of the TS-711A/E when the DCS system is ON.
You must prearrange which codes will be used, since once
you have turned on the system only the proper codes will
open the squelch.
18
D.SQ
< Operation >
1. Press the [DCS] key and then the [D.SQ] key. The DCS
system is now active. The DCS and D.SQ indicators
will light, and undesired signals will not open squelch.
2. Select the codes you wish the system to recognize by
turning on the appropriate stanby indicators.
3. When any of the selected codes is received the squelch
will open, an alert tone will sound, and the microproces-
sor will select the proper transmit code to allow normal
two-way communications.
4. Two different [DCS] alert signal functions are available.
When the [DCS] and the [D.SQ] keys are on and the
proper access code is received, the radio will beep 3
times and the [D.SQ] indicator will turn off.
When the [D.SQ], [C.AL], and [DCS] keys are on and the
proper access code is received, the radio will beep 3
times continuously until reset, and the [D.SQ] indicator
will turn off.
Use of these alert functions, in conjunction with the op-
tional CD-10 call sign display, will allow unattended
monitoring. When you return and discover that the
alert function has been activated you can recall the call
signs of those stations who have attempted to contact
you. Further information on the CD-10 is contained in
the operating manual for that accessory.
To reset the DCS system, press the [D.SQ] key, and the
[C.AL] key, if desired.
