Solder just one pin of P2 (but not the center pin, which is harder to re-heat due to the ground plane).
Verify that P2 is not tilted, and is seated completely flat. If not, re-heat the soldered pin and press down on
all of P2's pins until the connector drops into place. Once the connector is seated correctly and is not tilted,
solder the other two pins.
Install 8-pin male connector P1. (An end view of P1 is shown in the drawing above.) Solder just one
pin of P1, near the middle of the connector. Verify that P1 is now perpendicular to the PC board and is
seated completely flat. If not, re-heat the soldered pin and press down on all of P1's pins until the connector
drops into place. Once the connector is seated correctly and is not tilted, solder the remaining pins.
At this point only the locations for J1 and J2 should be empty. Use of these connectors is explained in
later steps.
Do a complete visual inspection of the PC board, on both sides, using a magnifying glass. Look for:
__ solder bridges; __ unsoldered pins; __ cold solder joints; __ backwards diodes or ICs.
This completes K60XV PCB assembly.
Installation
i
Installation of the K60XV module may require 1 to 2 hours or more to complete. Before
proceeding, you should already have installed and tested new K2 firmware if applicable (you'll need 2.04P
or later). Also, if your K2 serial number is 4087 or lower and you plan to install a replacement
heatsink/rear-panel with phono connector holes, you should have this panel available before you start.
Otherwise, you will not be able to complete the installation. (Alternatively, you can use the K2 top-cover
"XVTR IN/OUT" holes, or drill two phono connector holes in your existing heatsink panel. Both options
are covered in these instructions.)
Remove the K2's top cover or KPA100 module, unplugging all internal cables.
Remove the bottom cover panel (the panel with the tilt stand).
i
The lower rear panel/heat sink must be removed in order to install K60XV module connectors.
Follow the procedure below carefully so that none of the hardware will be lost or reinstalled incorrectly.
Remove the heat sink panel as follows: (1) remove six screws; (2) remove the hardware retaining the
antenna and key jacks; (3) if you have a 160 m module (K160RX), unplug it; (4) tilt the K2 up on its left
side, with the front panel facing forward; (5) remove the two nuts and lock washers holding the heatsink to
the PA transistors, but do not remove the PA screws; (6) push the PA screws back into the cabinet just
enough to allow removal of the heatsink panel, but do not allow the screws to fall out; (7) remove the
heatsink panel; (8) push the PA screws back down from the top side of the RF board; (9) install the two
nuts removed earlier onto the PA screws (hand tight) to hold all PA hardware in place as you complete the
remaining installation steps.
