Removing The Krx3A Or Krx3 Sub Receiver Module - ELECRAFT K3 Installation Instructions Manual

Remove the three 6-32 screws that secure the K144XV module to the side panel. Hold the module to keep
it from falling if the KRX3 sub receiver is not installed. Lift the module out, set the top cover on it to protect it,
and set it aside in a safe place.

Removing the KRX3A or KRX3 Sub Receiver Module

If you do not have the sub receiver installed, go directly to Removing the Bottom Covers and KIO3A/KIO3
Board on page 9.The sub receiver module is the "L" shaped metal enclosure (see Figure 3). Remove the sub
receiver module as follows:
Remove the chassis stiffener bar that runs across the top of the K3 chassis and is attached to the side panels.
If the KPA3A/KPA3 is installed, the stiffener will be attached to the shield by two screws. These screws may
have nuts and lock washers or they may thread into permanently-attached PEM nuts on the stiffener bar.
Remove the two 1-1/2" (38 mm) screws and lock washers shown in Figure 3. These screws extend all the
way through the sub receiver module and secure it to standoffs mounted on the main RF board that fills the
bottom of the K3.
In the following steps you will handle small TMP coaxial connectors. These are friction-
fit connectors shown in Figure 4. Handle the connectors by the grips as shown. Do not pull
on the coaxial cable.
