Connection To The Linear Amplifier; Connection To The Tl-922 - 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.
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:
◆ The TX/RX control method may vary depending on the type of external linear amplifier. Some linear amplifiers may enter TX mode when the
control terminal is switched to the ground line. For such a linear amplifier, allocate pin number 2 in the REMOTE connector to connect to the
GND terminal and pin number 4 to the control terminal of the linear amplifier.
◆ TL-922 have been discontinued and is no longer available.
