K60XV Module Installation
If a K160RX option (160 m and Receive Antenna) is installed, you may need to adjust the position of
the RX ANT ground lug to prevent interference with the K60XV board in the next step. This ground lug
should not be rotated to face upward, as it may contact one of the top-cover option modules (KAT2 or
KPA100). The lug should instead be rotated so that it is either below the RX ANT jack or so it fits into the
cutout on the K160RX module.
Plug in the K60XV module. Make sure the 3- and 8-pin connectors, P2 and P1, are properly mated
with J15 and J13 on the RF board. There will be some length of pin exposed on each connector, so that the
K60XV PC board height matches the height of the nylon standoff. Three slug-tuned inductors on the K2
RF board should appear approximately centered in the associated holes on the K60XV board.
i
The three slug-tuned inductor holes are provided so you can access all of the K2's band-pass filter
alignment points without removing the K60XV. However, it should normally not be necessary to adjust
these inductors during K60XV alignment.
Secure the K60XV module to the nylon standoff using a 4-40 x 1/4" (6 mm) screw and one #4 split
lock washer. Do not overtighten the screw, which could strip the threads in the standoff.
Re-install the bottom cover.
Verify that your K2 firmware is at revision 2.04P or later (by holding any key during power-on). If not,
you must upgrade it before you can complete K60XV alignment and test. Refer to the instructions supplied
with the firmware.
If you have a KAT2 internal ATU and its firmware has not already been upgraded to 1.07 or later, you
may want to upgrade it now. The KAT2 may be usable on 60 meters with an older revision of firmware,
but it will not cover a very wide impedance range.
If you have a KPA100 100-watt stage and you plan to use it on 60 meters, it must be upgraded as noted
on page 2 of this manual. If you choose not to upgrade it at this time, be sure not to attempt to transmit in
high-power mode on 60 meters.
This completes K60XV installation.
Note: Do not install the top cover or the KPA100 module at this time.
