Introduction

If your K144XV is already installed in your K3, turn to Using the K144XV on page 18 for operating

instructions.

The K144XV option adds 144 to 148 MHz receive and 10-watt transmit capability to your K3 via a separate
antenna connector on the rear panel. Complete specifications and operating instructions are included in your K3
Owner’s manual. This manual covers both installation and operation of the K144XV option.

Only a few basic hand tools are needed (see page 6) to perform the installation. A minimal amount of soldering
is required to install a power connector on the K3 RF board on some K3s.
