Kenwood Sky Command System

Innovative concept allows the HF operator freedom to walk and talk

with handheld remote control

The Kenwood Sky Command System (KSS) effectively puts an HF trans- ceiver 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.

It’s not just freedom you’ll enjoy: KSS is simple and intuitive, yet amaz- ingly 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.

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.

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.
