Repair / Alignment Service (We want to make sure everyone succeeds!) If necessary, you may return your Elecraft product to us for repair or alignment. (Note: We offer unlimited email and phone support to get your kit running, so please try that route first as we can usually help you find the problem quickly.) -
Page 4: Preventing Electrostatic Discharge Damage
How ESD Damage Occurs Whenever an object containing a static charge touches a circuit in your K3, current will rush into the circuit until the components reach the same voltage as the source of the static charge. If the voltage or current that passes through a component during that brief period exceeds its normal operating specifications, it may be damaged or destroyed. -
Page 5: Preparing For Installation
• If you choose to use a soldering iron to work on your K3 for any reason, be sure your iron has an ESD- safe grounded tip tied to the same common ground used by your mat or wrist strap. -

Page 7: Installation Procedure
HOLDING TOP COVER. Figure 1. Removing K3 Top Cover. CAUTION: Touch an unpainted metal ground or wear a grounded wrist strap before touching components or circuit boards inside the K3. See Preventing ESD Damage on page 4 for more information. - Page 8 WASHERS. Figure 2. Removing K3 Bottom Cover. As you install components and reassemble your K3, be sure all the screws are in place and secure, but do not over tighten them. Failure to tighten all screws may result in poor shielding of sensitive components, resulting in possible noise or birdies in the receiver as well as other difficult-to-trace problems.
- Page 9 Install two standoffs on the RF board that covers the bottom of the K3 as shown in Figure 3. (Note that the stiffening bar across the top of the K3 chassis has been removed to show the positions of the standoffs more clearly.)
- Page 10 4-40 3/16” (4.8 mm) screws . Be sure these are in the correct locations! CAUTION! Failure to replace the three 1/4” (6.4 mm) screws with their lock washers in the locations shown in Figure 2 may destroy power transistors in your K3!
- Page 11 Figure 5. Connecting Speaker Cable. Position the top cover on the K3. Note that the tab on the back center goes under the rear lip of the K3 rear panel. Secure the top cover with the nine 4-40 3/16” (4.8 mm) black flat head screws you removed earlier.
