n Setup Procedure
1) Turn ON the transceiver being used for TRP.
2) Set up its DTSS code and CTCSS frequency
on the 440 MHz band, its operation frequency
on the 144 MHz band, and its operation
frequency on the 440 MHz band. (These
settings must be the same as those in the CMD
mode).
3) Turn OFF the transceiver’s power.
4) Press and hold the PTT and CALL buttons,
and then turn ON the transceiver's power. The
following display appears when TRP mode is
set up successfully.
Note: Using a high CTCSS frequency may cause an audible
tone to be output from the speaker of the HF transceiver. If this
happens, select a lower CTCSS frequency which does not cause
the problem.
n Setup Cancellation
1) Turn OFF the transceiver’s power.
2) Push and hold the PTT and CALL buttons,
then turn ON the transceiver’s power.
Cancellation is successful when “Sky” and
“Trp” no longer appear on the screen.
TRP mode provides the specific condition for
providing transfer of the CMD and the signals of
the HF transceiver. The lamp and power change-
over keys can still function while in TRP mode,
however, you must return to the conventional
mode of operation before you can reset the
frequency.
Set the reception volume control for the 440 MHz
band at approximately center.
Note: In TRP mode, the power save and APO functions are
automatically turned OFF. Therefore, we suggest you use an
external power source. When you use the same power supply
as the HF transceiver, you are advised to take care of the HF/RF
feedback through the power supply line. In this case, the
supplied voltage of the TRP is the same as the HF transceiver,
so you should be careful to avoid overheating, or other
malfunctions, of the TRP.
RS-232C SETUP
4,800 bps, 8 data bits, and 2 stop bits are used for set
up. It is important that the RS-232C communication
speed is set up correctly. If the set up is not correct,
the HF transceiver will not operate properly.
REFERENCE: MENU numbers of HF
transceivers.
• TS-570D(G)/S(G): No. 35
• TS-870S: No. 56
HF TRANSCEIVER SETUP
Note: Only the TS-570D(G)/S(G) and TS-870S models can be used
with this system. Other KENWOOD products will not operate.
Please refer to the appropriate instruction manual of the HF unit for
operation of the HF transceiver.
Set up the frequency and mode for the operation of
VFO and M. CH. (When an external speaker is
connected to the line from the I/O UNIT, voice
signals cannot be heard. Keeping this in mind, when
you listen to and confirm a voice signal, you are
advised to either disconnect the line, or use a head
set). Set the functions of the HF transceiver which
the CMD cannot control, beforehand.
HF TRANSCEIVER:
• Set the AF volume control to the 9:00 to 10:00
position.
• Set the MIC gain to approximately the center.
• Set the squelch control to the fully opened
position.
COMMON ITEMS FOR
TRANSMISSION/RECEPTION
n Confirmation of Preparation
• Has the set up of the COMMANDER (CMD)
been completed? (See page 3).
• Has the set up of the TRANSPORTER (TRP)
been completed? (See page 5).
• Do the operation frequencies, the DTSS code,
and the CTCSS frequency of the CMD and the
TRP match?
• Has the set up of the HF transceiver been
completed? (See page 5).
n System Initial Set Up
1) Turn ON the power supplies of the CMD, the
TRP, and the HF transceiver (in any order).
2) Push the HF PWR ON key on the CMD (key
1). “CTRL” is displayed on the screen of the
HF transceiver. If “CTRL” is not displayed,
check the Confirmation of Preparation again.
3) To turn OFF the HF transceiver’s power, press
the HF PWR OFF key on the CMD (key 4).
After the power is turned OFF, no function
other than HF PWR ON can be performed.
Note: Turning OFF the power supply of the equipment during
KSS operation will stop the operation.
