Good man, that's the right attitude to construction, (and life).

Don and all,
Thanks for your replies.
I have read all the tales of distress and solutions to the mix of RS232 and
non-RS232 re the K2 interface. Don't want to go there.
The standard MicroKeyer to K2 lead set as far as I can tell seems to have a
RS232 D type connector presumably male to go
I encountered a problem when building KAT2. I'm in page 7 in revision D
manual.
The fifth step says:
Install the two 16-pin female connectors, J4 and J5, on the top of
the Control board... Make sure the connectors are
perpendicular to the board

I may not fully understand so excuse if I make no sense.
The plug coming out of the microkeyer represents your computer in the grand
scheme of things. So with your existing cable (as I assume works today)
where you would normally plug into the computer you would now plug into the
db9 shell coming
Stewart,
If the Microkeyer has connections only to pins 1, 2, 3 and 5 of the 9 pin
connector, one can safely plug it into the K2 directly.
In your case of an external KPA100, you have a existing cable connecting the
K2 to the KPA100. You will have to bring out another cable from the K2 end
Rolf,
You will have to somehow get J4 and J5 perpendicular to the board. Forcing
them into alignment with the screws will likely break something.
I have not had any past problems in accomplishing that feat. Be certain C60
and C45 are the proper values of 0.001 uf (marked 102) - the .001

I have a pair of wire strippers - they are shaped like nail clippers but are

through the varnish but not the wire.
However I also use heat - not enough to burn off but sufficient to make the

for a reliable QRO rig of the same value.

Lee,
I burn off the insulation using a GC brand Snap Vacuum Solder Popper.
Heat the iron, melt a bit of solder into the hole into the tip end,
insert the wire into the small hole at the iron tip up to the edge of
the toroid, allow the wire to heat until the insulation burns off, about

I didn't find my original posting anymore so I couldn't reply to the
original thread.
I took a sharp knife and took away some very thin plastic layers from
the surface of J4 (16-pin connector). Plastic was removed above the pins
from 7 to 10 and number 16. Now J4 is sitting perpendicular to
For my own K2, I have put a plug into pin 4 and broken off pin 4 of the
mating cable, so only that special cable can be plugged into the K2 to
prevent an accident that can happen to the best of us.
An excellent idea. It's not just Elecraft that do this; Kantronics

I felt precisely the way you do now when I received my K2 in July--the

tinned one.
Take some enamalled wire and practice tinning (don't burn your fingers).
Then wind and tin a few and see how you feel. I liken the
Chris and all,
The signals from the K2 are not likely to damage any external RS232 port,
normal RS232 drivers and receivers will handle the signals sourced by the
K2. BUT - RS232 port signals from the external device WILL DAMAGE THE K2 if
they source signals on the normal DSR, RTS, CTS or RI
Hi Bob
Thanks.
I just want to make sure it doesn't give trouble later.
I am using crystal400 halide free.
Actually , I was using crystal 511 multicore for various things and seems to
be OK.
Just I want my K2 to last all my life or may be most of my life.

Folks,
Jack Brindle sent this privately, but I must say he is correct - a computer
or external device that connects to pin 1 can create a ground loop. While
that will not likely harm anything electrically, it may make functions 'work
strangely'.
Jack and I both did a bit of web research of the
Hi:
The standoffs that hold J8 (the DB9 connector) to the back
panel aren't long enough.
They don't reach to the threads on the nuts.
Has anybody else had this problem?

Those standoffs do not have a lot of extra thread length, but they will fit
if everything is positioned correctly. Check first to determine if there is
any gap between the PC board and the rear panel - there should be none at
all. You may have the DB9 connector mounted at a slight angle
Hi All
Elecraft has a new minikit, a directional coupler model CP1. This kit can be
built as a 20 db or 30 db directional coupler. The coupler is usually used
with a spectrum analyzer but I find it works perfectly with my OHR WM-2 QRP
wattmeter.
Just connect the CP1 in series with your dummy
Hi Moe,
In my search for information on X39 flux, I found (via Google) some
information from Rapid Electronics which also descripes Crystal 400
and 511. It doesn't appear that there should be any problems with
either of these.
I tried to send you the data directly as an attachment, but

One should not assume that any particular connector implies any kind of

And to make matters worse, the real RS-232 standard calls for DB-25P
