You will need an RS232 port on your computer and the current Elecraft K144XV Utility program. If
your computer has only USB ports, you can use a USB/RS232 interface. You can obtain one that has
been tested in this application from Elecraft; order the KUSB Universal Serial Bus Adapter. KUSB
drivers are available for Windows, Macintosh and Linux operating systems.
IMPORTANT!
You need incorporate the following changes only if you are installing the K144XV Reference
Oscillator Phase Lock option at the same time that you are installing the K144XV 2-Meter Option.
1. Page 13: Add the following step immediately after Figure 6 (You can cut this out and attach it to the page
with a mark indicating to perform it before the last two steps on that page):
Disconnect the TMP cable from J83 on the Main KSYN3 board (mounted on the front panel shield closest
to the side panel you have removed; see Figure 4, TMP Cable Connections, in the K144XV Reference
Oscillator Phase Lock Option Installation manual). Leave the other end of the cable connected to J2 on the
KREF3 board. Take the TMP cable from your K144XV Ref Lock kit and plug it into J83 on the KSYN3 board.
You will plug both of these cables into K144XV after the module has been installed. Be sure to position the
cables so you can reach them after installing the K144XV module in the following steps.
2. Page 14: After Figure 7, add the following step:
Refer to the K144XV Reference Oscillator Phase Lock Option Installation manual and install the Phase
Lock board as shown in Figure 3, Installing the Phase Lock Board, on page 7, and then connect the TMP cables
as described on page 8 and in Figure 4, TMP Cable Connections.
