Operation Manual

This operation manual is used for the KENWOOD SKY COMMAND SYSTEM (hereinafter referred to as KSS), which is compatible with the TH-79AKSS and TH-D7A, which is available for sale on a limited basis.

KENWOOD SKY COMMAND SYSTEM

TH-D7A:

Refer to the TH-D7A Instruction manual (page 83) for instructions on how to use the KSS with the TH-D7A transceiver.

Notes: PG-4R modification necessary when KSS II operation with the TH-D7A.

Please cut the white wire carefully (TH-D7A ONLY).

KSS provides a wireless microphone system over a short distance. Accordingly, KSS is very useful in the following situations:

• Watching for DX, schedules, or tuning the bands while working around the house.

• Operating HF radio while relaxing in your living room, instead of in the shack.

• Operate without carrying a wired microphone around the shack.

• Operate HF while camping, picnicking, or at local sporting events (HF in the mobile).

At present, KSS is capable of communication in voice mode. Please use SSB/AM/FM modes.

To get the most out of this system, KSS allows HF memory channel operation, and fixed frequency operation, even if VFO is used. It is more effective if you operate by selecting HF operation frequencies and modes beforehand. KSS can control RIT, if required. In addition, KSS can operate VFO and can change the frequency in steps. Therefore, the conventional operating method of tuning the VFO is not suitable in this system.

TH-79AKSS:(Does not work on the other TH-79 series)

KSS provides a system wherein the portable transceiver is used as a wireless remote control, microphone, and repeater used in operation with the TS-570S(G)/D(G) and/or TS-870S HF transceivers. Wireless remote control operation has been achieved through the utilization of the portable transceiver’s DTMF and CTCSS functions, and the HF transceiver’s PC control functions.

This system is capable of transmitting and receiving HF radio signals, changing over from transmit to receive, setting frequencies, switching memory channels, and other functions.

440MHz band: Control signal to the HF transceiver

•

The operator controls the HF transceiver from the portable COMMANDER (CMD) TH-79AKSS.

•

The received HF signal is re-transmitted by the TRANSPORTER (TRP) TH-79AKSS on the 144 MHz band.

•

Voice is transmitted from the CMD unit on the 440 MHz band.

•

The control signals, for frequency and functions of the HF transceiver, are sent from the CMD unit on the 440 MHz band.

•

With the (optional) VS-3 voice unit installed in the HF transceiver, the operator can confirm the HF frequency.

identification. FCC Rule

97.119, Station Identification. Each amateur station, except a space station or telecommand station, must transmit its assigned call sign on its transmitting channel at the end of each communication, and at least every 10 minutes during a communication, for the purpose of clearly making the source of the transmissions from the station known to those receiving the transmissions. No station may transmit unidentified communications or signals, or transmit as the station call sign, any call sign not authorized to the station.
