Connection To The Linear Amplifier; Connection To The Tl-922; Connecting A Typical Linear Amplifier - Kenwood TS-990S Instruction Manual

1 INSTALLING AND CONNECTING THE TRANSCEIVER

CONNECTION TO THE LINEAR AMPLIFIER

You can connect a linear amplifier to the REMOTE connector.
Prior to activating the linear amplifier, ensure that you have configured the linear amplifier
controls. {page 16-31} {page 16-32}
10 ms is the response time from when the transceiver changes from receive to transmit to when is actually transmitted.
In operation other than CW Full Break-in, changing the menu configuration extends the response time to 25 ms (45 ms
for SSB, FM and AM modes).
Note:
◆ TL-922 have been discontinued and is no longer available.

CONNECTION TO THE TL-922

Supplied 7-pin DIN Plug (Use a self-made connection cable using the 7-pin DIN
plug supplied with the transceiver.)
CONTROL RELAY
Allocate pin number 2 (COM) in the REMOTE connector to connect to
the GND of the TL-922, and pin number 4 (MKE) to the RL CONT of the
TL-922. Additionally, connect pin number 6 (ALC) to the ALC OUT of the
TL-922.
Configure Advanced Menu 11 "Linear Amplifier Control (HF Band)" to
"Active High + Relay & TX Delay Control".

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 -7V to -10V.
◆ Refer to the instruction manual supplied with the linear amplifier for connection to the linear amplifier.
