Rtty Equipment; Linear Amplifier; Antenna Tuner - Kenwood TS-570D, TS-570S Instruction Manual

RTTY EQUIPMENT

Use the ACC 2 connector to connect to the RTTY equipment. Connect the RTTY key output line to pin 2 of the ACC 2
connector. Connect the demodulation input line of the RTTY equipment to pin 3 of the ACC 2 connector.
Note: Do not share a single power supply between the transceiver and the RTTY equipment. Keep as wide a separation as possible between the
transceiver and the RTTY equipment as practical to reduce noise-pickup by the transceiver.

LINEAR AMPLIFIER

Connect an external transmit power amplifier to the REMOTE connector. Before using the external amplifier, switch
ON the linear amplifier control relay via Menu No. 39.
The TX/RX relay response time is 10 ms when you have selected CW Full Break-in and 25 ms when you have
selected CW Semi Break-in.
Note: The TX/RX control method differs depending on external amplifier models. Some amplifiers enter the TX mode when the control terminal is
grounded. For those amplifiers, connect pin 2 of the REMOTE connector to the GND terminal of the amplifier and connect pin 4 of the connector to
the control terminal of the amplifier.

ANTENNA TUNER

Use the ANT 1 connector and the AT connector to connect an external antenna tuner. If you connect the external tuner
to the ANT 2 connector, the external tuner will not function.
Note: While using an external antenna tuner with the TS-570S, you cannot use the 6 m band to transmit. Connect your 6 m band antenna to the
ANT 2 connector.
