Dennis,
If you do not have a good dummy load, I suggest the DL1 as a first priority.
Follow that with the N-Gen to use when aligning your filters using
Spectrogram, and then the XG1 or XG2 to give you a good reference point for
setting the S-9 point on your S-meter. If you are into SSB and want t
I have the noise generator, dummy load and signal generator. All are
extremely useful and I really suggest having them. Of course, none of
them (except a dummy load) are needed when building the kit, but they
sure make it a lot easier.

Hey Elecrafters, With respect to the K2, which elecraft mini module would be
the best asset for alignment or trouble-
shooting? I realize each piece does a specific job, but
I am really new to kit building. Plus I want something else to
practice my soldering on besides the K2 itself.Hi! Hi!

Hello all,
While pack packing in the cold weather this past weekend, I noticed that
my "pimped-out" KX1 had dropped down to 2w power output after about a
hour on the air. I thought it was due to the batteries and the cold -

Today I opened up my KX1 and checked each Li-ion battery with a

Jeff,
If the PLL/VCO works, in all likelyhood, the thermistor board is
functioning. If one wants to know how well it is working, drift
measurements would have to be made after the K2 is assembled and tested in
all other aspects. Making drift measurements is a tedious endeavor and to

Dave,
If you look at the back of the thermistor board, there is one place where 3
resistors come together just above pins 4 and 5, those are connected
together. OTOH, a bit toward the right of that point you will see two
resistors with the ends pointing at each other and the PC traces are quite

Probably drift as you say. If the PLL Reference Oscillator Range test or VFO

The old rule was 5xWPM in Hz for a properly-shaped CW signal. I
remember studying this for my Novice.
Is that still accepted?

Hi Ian,

if you were on upper side band cw you could cosy right up to the lower

I just had two QSOs with my K2, the closest to any band edge
I've ever ventured in nearly 28 years of operating.
I heard F6FAI calling CQ and my K2 frequency was 7.0005 MHz.
I trusted that Jean was inside the band and I had set my

Yea, it is a mess. I have one bridge, but I think that is where they
come together anyway (the tail end of three of the resistors right next
to the connector) because I can't get it cleared up. If I have problems
that are on that circuit, it will be the first place I look.

Dave,
It's tight, but everything will fit. Be sure the leads coming out of the
thermistor board bend immediately 90 deg to the RF board.
Also take a good long hard look at your solder joints on that little thing.
The holes are not clad, so solder does not flow there like the rest of the ki
I just went to the Heil website and verified the ProSet-Ic has an

When I put mine in, I noticed that I had messed up and put the wires
running out the wrong side of the board. That makes a big difference
in how it fits. I left mine as is, and no problems at all with
shorts, though I have this thing in the back
Build it small, build it tight. I used a hydraulic press to make sure
the components were pushed down tight to the board before soldering
... well, maybe not :-) ...
But it does pay to keep things as small and tight as reasonably possible
so you'll have some space around the board.
