Kenwood TH-D72E - Manual (Page 71)

SKY COMMAND SYSTEM II
The SKY COMMAND SYSTEM II allows remote control of a TS-2000, TS-2000X, TS-B2000, TS-480HX, TS-480SAT, TS-
590S, TS-570D, TS-570S, or TS-870S HF transceiver.
You will use one transceiver as a control station called “Commander”. The transceiver connected with the HF transceiver
is called “Transporter”. It will function as an interface between the Commander and the HF transceiver. This system
allows you, for example, to watch for and hunt DX while washing your car, or to operate the HF transceiver while relaxing
in your car, living room, or patio, instead of in your shack.
The Commander and Transporter transfer audio and commands as below:
SKY CMD – 1
CONNECTING THE TRANSPORTER WITH THE HF TRANSCEIVER
In order to connect TH-D72 to the HF transceiver, you need to prepare three cables by yourself. The COM terminal on
this transceiver accepts a 2.5 mm (1/10") 3-conductor plug. If necessary, use the cable (service part: E30-3400-XX) to
modify the cable end of RS-232-C connector.
Note:
X Operation of Sky Command System II may not been permitted in certain countries. Check your local laws before operating.
X Switch OFF both the Transporter and HF transceiver before making the connection.
X The Transporter automatically transmits its call sign in Morse at regular intervals because of legal requirements; therefore, transmit side tone
must be output from the HF transceiver.
X When the Transporter is too close to the HF transceiver, unwanted feedback may cause malfunction.
X Do not share a regulated power supply between the Transporter and the HF transceiver. Unwanted feedback may cause malfunction.
