OK Folks:
Once more, with feeling...
I have (at 1715Z, today) posted the info on the K2 RIT-SPLIT LED mod to my
web site. Actually, this is a new document which included a lot more
information. Unfortunately, it's also nearly 3MB in size, so PLEASE do NOT
view the file on-line. Please DOWNLOAD it to your hard drive and THEN view
it. If you happened to find an earlier (today) posting of the mod on my web
site, you might want to re-D/L this version.
The file (PDF) can be found at:

Once at my home page, go to the bottom of the home page and click on the
DOWNLOAD PAGE link. The article is in the "K2-RELATED FILES" section.
PLEASE NOTE that this is NOT an' official' Elecraft mod!!! Although the
design is Wayne's, the implementation is purely mine.
And no, PC boards are NOT AVAILABLE from elecraft, nor are the available
from me, at least at present. Though I may consider making some a bit later
on this winter. Cost will probably be $5 ppd to your door (U.S. and
Canada). There's little to the PC board. In fact, if you have a DremelTool
and a small piece of PC board, you can use the DremelTool to 'route' the
pattern onto the PC board. It doesn't have to be pretty... it just has to
work. I can supply a much less 'pretty', but much easier to route, PC board
design if you choose to use this method of making your own PC board.
This is NOT a mod for the faint of heart... one slip with the drill on the
front panel of the K2 case and you're a goner! There's very little 'wiggle
room' available with the LED, to get it properly positioned and you will
have to use care during the installation.
You CANNOT use just any LED either. It MUST be a HI-EFFICIENCY (or possibly
an ULTRA-BRIGHT) LED which can supply ample light output when drawing only
2 to 3 mA of current...!! This is a limiting factor in choosing which LED
you'll use, and you should TEST your chosen LED _at_ 2-3 mA, to ensure it
will work acceptably BEFORE you undertake this project.
Enjoy.
