Kenwood TH-D7A Instruction Manual page 89

The Sky Command 2 allows remote control of a
TS-570D, TS-570S, or TS-870S HF transceiver. This
system requires two TH-D7As and the optional cables
which connect one TH-D7A to the HF transceiver. You
will use one TH-D7A as both a remote control and
speaker microphone. This TH-D7A is called
"Commander". The TH-D7 connected with the HF
transceiver is called "Transporter". It will function as an
interface between the Commander and the HF
transceiver. The Sky Command System allows you, for
example, to watch for and hunt DX while working around
the house, or to operate the HF transceiver while
relaxing in the living room or patio, instead of in the
shack.
