6 Kenwood Sky Command System The Kenwood Sky Command System (KSS) effectively puts an HF transceiver in your hand, allowing you to relax in your lounge or backyard while controlling the TS-570D/S(G) in your shack. Or you could be sitting at a baseball game while operating the HF transceiver safely installed in your car. And the new Sky Command II adds the convenience of LCD confirmation of HF frequency. Its not just freedom youll enjoy: KSS is simple and intuitive, yet amazingly powerful. Once the Transporter (TH-79AKSS or TH-D7A)* has been wired to your TS-570D/S(G) HF transceiver, all you need to carry is the second handheld (the Commander). The Commander transmits control signals to the Transporter, which also relays your voice to the HF radio. In return, HF signals are transmitted back to the Commander. This system allows you to transmit and receive HF signals, set frequencies, switch memory channels, and much more all from your handheld transceiver. * Sky Command requires two TH-79AKSS units, while Sky Command II uses a pair of TH-D7A transceivers. Innovative concept allows the HF operator freedom to walk and talk with handheld remote control Kenwood Sky Command Employing a pair of TH-79AKSS transceivers as Commander and Transporter, the Kenwood Sky Command system has proved extremely effective in freeing the HF operator from his shack. The DTMF keys enable simple pushbutton operation of all major parameters on the TS-570D/S(G). And if the optional VS-3 voice unit is added, you can enjoy audible confirmation of the frequency setting. You can thus hunt DX while working around the house or garden. Kenwood Sky Command II Sky Command II enables full-duplex operation, adding some extra features that further enhance functionality. For example, you can confirm HF frequency visually on the LCD panel of the Commander (TH-D7A). Control is effected via TNC (AX.25), and now even more HF functions are accessible: XIT, mode switching (USB, FM, etc.), split-frequency operations on/off, memory shift, and frequency step selection. In addition, once every 10 minutes, the Transporter (TH-D7A) will send out its pre-programmed call sign via CW. Voice signals Control signals HF receive audio Voice confirmation of HF frequency 440MHz band 144MHz band Confirmation of HF frequency 440MHz band HF receive audio 144MHz band The operator controls the TS-570D/S(G) HF transceiver from the portable Commander (CMD) TH-79AKSS. Voice is transmitted from the CMD unit on the 440MHz band. Control signals are also sent from the CMD unit on the 440MHz band. The received HF signal is re-transmitted by the Transporter (TRP) TH-79AKSS on the 2M band. With an optional voice unit (VS-3) installed in the TS-570D/S(G) HF transceiver, the operator can confirm the HF frequency. The operator controls the TS-570D/S(G) HF transceiver from the portable Commander (CMD) TH-D7A. Voice is transmitted from the CMD unit on the 440MHz band. Control signals are sent from the CMD unit on the 440MHz band. The received HF signal is re-transmitted by the Transporter (TRP) TH-D7A on the 2M band. The operator can confirm the HF frequency on the LCD of the CMD.
