Replace the chassis stiffener using the screws you removed earlier. If your original stiffener lacks the

cutout required for the K144XV as shown in Figure 10, use the stiffener supplied with your K144XV kit.

Enabling the K144XV Module

The following steps configure your K3 for use with the K144XV option.

Reconnect power to your K3 and turn it on.

Hold CONFIG and note the K3 firmware revision displayed. It must read 4.12 or later. If necessary,

download and install the latest firmware from www.elecraft.com

before proceeding.

In the CONFIG menu, set the parameters shown below. Note: This table assumes you’re using transverter

band 1 for the K144XV. (XV1). If you already have one or more external transverters connected to the K3, you

can select a different band for the K144XV. For example, if you wish to use band XV2, tap ‘2’ on the numeric

keypad before setting up parameters. When you are finished, tap CONFIG to leave the menu.

Menu Entry (VFO B) Parameter (VFO A)

XV1 ON YES

XV1 RF 144

XV1 IF 28

XV1 PWR L 1.50 (see note 1)

XV1 OFS 0.00

XV1 ADR Int. Trn0 (see note 2)

NOTES:

1) 1.0 mW is the normal drive level for full output. See Output Power Adjustment on page18for more

information about properly adjusting the drive and output power levels.

2) Setting

ADR to Int Trn0 tells the K3 than the internal 2 meter module is being used rather than an

external transverter. This sets up the KXV3A correctly and enables automatic K144XV crystal

switching at the 146-MHz boundary.

Int Trn1 through Int Trn9 are provided for using the K144XV to

drive higher-frequency transverters (see Using External Transverters with the K144XV on page 20.)
