Connecting A Typical Linear Amplifier; Connection To Other Kenwood Transceivers With A Tnc Terminal - Kenwood TS-990S Instruction Manual

CONNECTING A TYPICAL LINEAR AMPLIFIER

To connect a commercially available linear amplifier to the transceiver, follow the instructions given in the illustration below.
Note:
◆ Use a linear amplifier that has the ALC output level in the range from 0 V to -7 V. Do not use a linear amplifier that has the ALC output level
outside the 0 to -7 V range. This may cause distortion and transmit power reduction by faulty ALC performance and abnormal oscillation.
◆ Refer to the instruction manual supplied with the linear amplifier for connection to the linear amplifier.
CONTROL RELAY
Activates if "Active High + Relay" or "Active High + Relay & TX Delay
Control" has been configured for Advanced Menus 11, "Linear Amplifier
Control (HF Band)", and 12, "Linear Amplifier Control (50 MHz Band)".

CONNECTION TO OTHER KENWOOD TRANSCEIVERS WITH A TNC TERMINAL

The connection illustrated below allows packet cluster tuning using a TH-D72A/E, TM-D710A/E, or TM-
D700A/E. {page 16-27}
You can connect the TS-990S to a TM-D710A/E or RC-D710 using an optional PG-5G and a commercially available RS-
232C cross-cable. If the RS-232C cross-cable has female plugs or male plugs, use a female to male conversion plug.
You can connect the transceiver to a TM-D700A/E using a commercially available RS-232C cross-cable.
Note:
◆ TM-D700A/E has been discontinued and is no longer available.
◆ Refer to the instruction manual supplied with the device with the built-in TNC for details of connection.
