	CONNECTING THE TRANSPORTER WITH THE HF
1	TRANSCEIVER
	You can use the optional cables (PG-4R) to connect the
2
	Transporter with the HF transceiver. For these cables,
3
	contact your authorized KENWOOD dealer.
4	Note:
5	◆ Switch OFF both the Transporter and HF transceiver before making
	the connection.

6◆ The Transporter automatically transmits its call sign in Morse at

7regular intervals because of the legal requirement; therefore, transmit sidetone must be output from the HF transceiver. On TS-570D or

8TS-570S, do not select “OFF” in Menu 21. On TS-870S, use the MONI control to adjust the volume of sidetone.

9◆ When the Transporter is too close to the HF transceiver, unwanted

10feedback may cause malfunction.

◆Do not share a regulated power supply between the Transporter and

11the HF transceiver. Unwanted feedback may cause malfunction.
