In the following steps you will handle small TMP coaxial connectors. These are friction-

fit connectors shown in Figure 3. Handle the connectors by the grips as shown. Do not pull

on the coaxial cable.

Figure 3. TMP Coaxial Connectors.

Hold the KRX3 module by the two brass knurled nuts on the top, and lift it straight up to gain access to the

small TMP coaxial connectors plugged into the module. There are two along the front. There may be one at the

back as well, depending upon the options installed. As you lift the KRX3 module, it will unplug from two small

interface circuit boards. One is at the front and the other is at the rear. These small boards may come out with

the module or they may remain attached to the K3 main RF board.

Unplug the TMP coaxial cables leading to the KRX3 module, then lift the module free and set it aside.

Locate the two small interface circuit boards that fit between the connectors on the KRX3 module and the

connectors on the K3 RF board. Remove them and put them in a safe place.

Installing the KBPF3 in the KRX3 Subreceiver

If you are not installing a KPBF3 in the subreceiver, go directly to Installing the KBPF3 in the K3 Main

Receiver on page 11.

Unscrew the two knurled nuts shown in Figure 4 and lift the top half of the enclosure off. There are two

unthreaded sleeves over the long screws above the circuit board that will slide off easily (see Figure 5). Be sure

you don’t lose them.
