Hi Nigel,
I'm not sure how to reverse the direction of the VFO when turning the
knob clockwise. I can understand how that would be counterintuitive to
what you are used to on other radios. I just completed my KX1, S/N
1644, and it seems to be clockwise = increase frequency.

Do you have the encoder mounted on the wrong side of the board? Since all
the wiring is on the PC board, that is the only way I can think of to change
the encoder direction.
That is not normal - check to be certain you do not have a solder bridge or
unsoldered connection somewhere: At
Hi, Nigel!
I'm sorry to have to tell you this, but your KX1 was kitted with the
wrong type of encoder for the VFO control. The normal type of encoder
has a blue body, the reverse type has a white body. Lisa at Elecraft
has spent the last two weeks trying to contact all recent purchasers of
I don't know as I am not familiar with the KX1 but I presume they are using
an optical encoder to clock the frequency up and down. Is there a
possibility that the encoder leads were installed in reverse ?

Thanks to everyone for your replies.
I guess by now you will have read Brian's email to see that a few kits went
out with reverse encoders (southern hemisphere models as one reply suggested

It sure feels funny tuning a radio in the reverse direction!
As usual, all at Elecraft have
Hi Nick,
Gud luck with your K2...winding the coils is tedious but not difficult (in my
opinion. Get yourself a good maginfying glass and recount the turns after you
are finished. Allow yourself an a bit more length then when you cut the wire,
you can also trim it later, you'll have plenty
Hi Nick,
I'm a beginner kit builder also, and just finished my first K2.
I, too, was worried about the toroid windings. I went ahead and tried
it, and it really isn't that bad.
I found that Elecraft gives you more than enough wire, so err on the
side of a longer wire than called for by an inch

The diagrams in the manual are very clear in showing
the direction of the windings. Follow them exactly as

Nick, you have NOTHING to worry about. Coils are simple. Yes, they
can be time consuming when you get something with a bunch of winds on
it, but it is not hard at all. It just requires some concentration

The biggest thing is stripping and tinning the leads. I have a De-soldering
station that works very well to run the leads into the hole and strip with
heat and solder. But you can carefully scrape the enamel off or use a very
fine grit sandpaper to strip them and then tin them very well and look
Nick,
I do not understand why folks have a mental block about winding toroids - it
is easy for folks with normal manual dexterity.
A couple hints about winding - count each turn as it passes through the
center of the core - a single wire through the center is 1 turn. For large
lengths of wire,
Nick:
One problem I had winding coils was the first turn always was looser
than the rest. So I would intentionally wind an additional turn and
then remove the first turn. Just make sure you end up with the correct
number of turns.
Also, after the coil is wound, before I try to strip the
Hello all:
This morning I was monitoring 30 meters with my K2, when
there was a grid power failure (off-on-off, very rapidly). When
the power came back on, and when I turned on the K2,
something is now amiss with the receiver on 30 meters: now
there are closely-spaced constant cw-sounding
Addendum to early post on spurious signals problem:
Actually, the aforementioned spurious signals seem to be
present on the other bands as well, though much attenuated
compared with on 30 meters.

Hello, Nick.
I say wind them yourself. I faced the same dilemma. The first one or two
may seem awkward, but you will be more proud of your accomplishment when you
hear the first signals. Pay attention to which way you start the winding.
You can get that from the manual and the pictures.
Sorry for the addendums...
Whatever the problem is, I guess it's not with my K2. I'm also
getting the same spurious signals with my K1, and with my old
ICOM 735, neither of which were powered up at the time of the
power failure.
Very mysterious.

Better the UPS than the K2. It did its job of protecting what was

One of the strengths of the K2 is its single-conversion design. That is, in
