Touch an unpainted metal ground or wear a grounded wrist strap

before touching components or circuit boards inside the K3. See Preventing ESD Damage

page 4 for more information.

Removing the KRX3 Subreceiver Module

If your K3 is equipped with the optional KRX3 Subreceiver, you must remove the subreceiver module to install

the KBPF3 in either the main receiver or the subreceiver. The KRX3 subreceiver module is the “L” shaped

metal enclosure (see Figure 2). Remove the subreceiver 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 KPA3 is installed, the stiffener will be attached to the KPA3 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 2. These screws extend all the

way through the KRX3 module and secure it to standoffs mounted on the main RF board that fills the bottom of

the K3.
