Antenna Tuner (AT)

If using an external AT-300 antenna tuner, connect it here using the cable supplied with the antenna tuner. The AT-300 must be connected to ANT 1; it will not function if connected to ANT 2.

TS-870S

SM-230 Station Monitor (IF OUT 1)

Connect a cable from the IF OUT 1 jack to the IF IN jack on the SM-230 Station Monitor. This cable couples the 8.83 MHz IF from your TS-870S for pan display on the Station Monitor.

Accessory Equipment (ACC 2)

If you intend to use this transceiver for any of the digital modes, connect the input/output connections from a Terminal Node Controller (TNC) for Packet operation, a Multimode Communications Processor (MCP) for operation on Packet, PacTOR, AMTOR, G-TOR, or FAX, or a Clover interface to this connector.

SSTV and phone patch equipment can also be connected to ACC 2. SSTV operation is possible by connecting the input/output from a computer sound card to ACC 2, then running an SSTV application on the computer.

To operate on the digital modes, you will need the following equipment:

¥Personal computer with communications software (alternatively, a ÒdumbÓ terminal capable of sending ASCII commands)

¥TNC (Terminal Node Controller) or MCP (Multimode Communications Processor)

¥TNC or MCP power supply

¥RS-232C cable

¥13-pin DIN plug and cable

Connect your TNC or MCP to the ACC 2 connector on the transceiver Rear Panel using a cable equipped with a 13-pin DIN plug.

Do not share a single power supply between the transceiver and the TNC or MCP. Keep as wide a separation between the transceiver and computer as practical to reduce noise-pickup by the transceiver. Refer to the accompanying table for connection information.
