SKY COMMAND SYSTEM II The SKY COMMAND SYSTEM II allows remote control of a TS-2000, TS-2000X, TS-B2000, TS-480HX, TS-480SAT, TS590S, 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. VHF Freq. UHF Freq. The Commander and Transporter transfer audio and commands as below: VHF freq. Audio UHF freq.

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.

Check your local laws before operating. ◆ Switch OFF both the Transporter and HF transceiver before making the connection. ◆ The Transporter automatically transmits its callsign in Morse at regular intervals because of legal requirements; therefore, transmit side tone must be output from the HF transceiver. ◆ When the Transporter is too close to the HF transceiver, unwanted feedback may cause malfunction. ◆ Do not share a regulated power supply between the Transporter and the HF transceiver. Unwanted feedback may cause malfunction. SKY CMD - 1
