CONNECTING THE TRANSPORTER WITH THE HF
TRANSCEIVER
In order to connect the transporter to the HF transceiver,
you need to prepare three cables by yourself. For the
connection between the COM connectors on the two
transceivers, you may use a commercially available RS-
232-C cross-wired cable.
Note:
◆
Switch OFF both the Transporter and HF transceiver before making
the connection.
◆
The Transporter automatically transmits its call sign in Morse at
regular intervals because of legal requirements; therefore, transmit
sidetone must be output from the HF transceiver. On TS-570D or
TS-570S, do not select “OFF” in Menu 21. On TS-870S, use the
MONI control to adjust the sidetone volume.
◆
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.
