ELECRAFT KX3 PHYSICAL DESCRIPTION

AND AUDIO-MORSE USER INTERFACE

Rev E1, 6-15-2012

Applies to firmware revision 1.06

INTRODUCTION

This document is intended to familiarize blind operators with basic operation of the Elecraft KX3.

Locations of controls and connectors are described. Control descriptions include the associated

audio Morse code characters and/or switch tones.

The user should also read the KX3 ownerʼs manual, which covers operation in detail. (A Braille

version of the ownerʼs manual is in progress.)

Note: At present, some controls may not include audio Morse feedback, making them difficult or

impossible to use without the display. Our goal is to eventually provide access to all KX3 functions

via the audio interface.

PHYSICAL OVERVIEW OF THE KX3

The KX3ʼs enclosure, not counting knobs, etc., is 1.7" high, 3.5" deep, and 7.4" wide. The

enclosure is made up of a top and bottom cover. The covers are held together by four thumb

screws at each of the four lower corners.

During normal operation, the KX3 is used in a trail-friendly orientation, nearly parallel to the

operating surface (table, etc.), but with its rear edge tilted upward. There are two tilt feet in the rear

that serve this purpose, in a manner similar to the rear tilt feet on a computer keyboard. To deploy

the tilt feet, loosen (but do nor remove) the two rear-most thumbscrews, fold down the feet

completely, then tighten the thumscrews again. Do not go beyond finger-tight as this may make the

thumb screws difficult to loosen later.

To gain access to the interior of the KX3 for changing batteries, all four thumb screws must be

loosened (but not removed). The top and bottom covers can then be separated. Note: The KX3 will

put out more power when running from an external supply. Batteries are recommended as a

backup, or when using the radio hand-held. If you use NiMH batteries, you can recharge them with

the optional KXBC3 battery charger/real-time clock module, reducing the need to periodically

change batteries.

The rear edge of the enclosure includes a heat sink, a thin plate about 7 x 1 inches that is secured

to the bottom cover. The heat sink may become quite warm to the touch when the KX3 is operated

at high power level or for extended key-down times.
