Amplifier Connections for Basic Operation
Figure 5 shows the connections to the amplifier when it is used with transceivers other than the KX3, or with a
KX3 without the optional KX3-KXPA100 Adapter Cable.
An amplifier with the optional KXAT100 antenna tuner is shown. If your amplifier does not have the antenna
tuner option, you will have only one
ANT
connector. Otherwise there is no difference in the connections.
The transceiver must have a key out connection that grounds the key line to enable the amplifier for
transmitting. Otherwise you will need to provide a means for manually grounding this line. If the line is not
grounded, RF from the transceiver is passed through without being amplified.
See the notes on the following page for a description of each connection.
