Page 5: Preventing Electrostatic Discharge Damage
Preventing Electrostatic Discharge Damage Sensitive components may be damaged by Electrostatic Discharge (ESD) simply by touching them or a circuit board containing them unless you take specific steps to prevent such damage. Damage may occur with static discharges far too little for you to notice. A damaged component may not fail completely at first. -

Doing so may damage sensitive components. See Preventing Electrostatic Discharge Damage on page 5 for important information. Before starting, check to be sure that you have the parts listed below. KXAT100 Core Assembly Box E850594 ELECRAFT ILLUSTRATION DESCRIPTION QTY. -

KXAT100 Hardware Envelope E850601 ELECRAFT ILLUSTRATION DESCRIPTION QTY. PART NO. M-F Standoff, 4-40 3/4" (1.9 cm) E700293 Switch Cap E980250 Lock Washer, Split Ring, #4 E700010 Assembly Procedure IMPORTANT ASSEMBLY INFORMATION Check off the steps as you finish each one. Skipping a step is easy to do without taking a moment to be certain that you completed the previous step. - Page 8 All of the screws that you will remove are identical and interchangeable. Also, they are the same length as the screws you got with the KXAT100. Take care to save all of them and the other hardware you remove to reassemble the amplifier.
- Page 9 On the rear panel, remove the nut holding the RS232 (PC) connector as shown in Figure 3. Figure 3. Removing the RS232 Connector Nut. Remove the six screws, lock washers and spacers on the rear panel as shown in Figure 4. The rear panel will be held in place by the coaxial cables to the SO-239 connectors.
- Page 10 Carefully unplug the coaxial connectors as shown in Figure 5. The TMP connectors are a friction fit and will pull straight up. Use your needle nose pliers to grip the metal connectors if space is too tight to reach them with your fingers.
- Page 11 The KXPA100 circuits are contained on two pc boards: the power amplifier (PA) module mounted on the heat sink and the low pass filter (LPF) module mounted on standoffs above the PA module. Remove the four screws and lock washers holding the LPF module to the standoffs and replace them with standoffs and lock washers as shown in Figure 7.
- Page 12 Taking ESD precautions, remove the KXAT100 ATU module pc board from its packaging. Place it on the standoffs you just installed so that the two plugs on the ATU module mate with their corresponding sockets on the LPF module as shown in Figure 8. Be sure that both connectors are properly aligned so all of their pins engage.
- Page 13 Secure the ATU module pc board to the four standoffs using the screws and lock washers you removed earlier as shown in Figure 13. Note that there is a hole near the center of the ATU module that is not used. Figure 9.
- Page 14 On the rear panel that you removed earlier, remove the hole plug from the ANT 2 opening. The plug has small parts that latch it against the inside surface of the rear panel. Squeeze them so they will slip through the opening to release the plug.
- Page 15 Connect the cables with the TMP connectors on the rear panel to the LPF and ATU module pc boards as shown in Figure 12. CAUTION Failure to properly connect the cables may result in damage to your KXPA100. Figure 12. Connecting Rear Panel Cables to the LPF and ATU PC Boards. Pass the small jack through the hole marked on the rear panel and secure it with the hex nut RS232 (PC)
- Page 16 CAUTION When replacing the bottom U-cover in the next step, be sure it is oriented with the lettering toward the rear panel as shown in Figure 6. Reversing the orientation will cause the threaded bushings for the handle to strike the circuit boards. Replace the bottom U-cover so the end with the label nearest the rear panel (the correct orientation is shown in Figure 6).
- Page 17 (see Figure 1on page 8). That completes the installation of the KXAT100 Antenna Tuner module in your KXAT100 Amplifier. Complete operating instructions are included in your KXPA100 Owner’s manual.
