Sorry Guys,
I must have had ssb stuck in my head even though I knew Ian had asked
about cw. Thanks for the polite correction.
This could mean my wife is right about my listening.

Hi Paolo,
have you heard about SOTA (SUMMITS on the AIR)? If not read about it on
the Web. Write about your QRX on the SOTAwatch and you will have real

Either I am missing something or this is just crazy. I have the board

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.

I've got the Heil ProSet-Ic with the Icom (blue) adapter from Heil.
However, I'm not sure if I need to connect the K2 mic connector pin 2 to

I just went to the Heil website and verified the ProSet-Ic has an

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
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.

Along these lines, is there a way to know that the thermistor board is
working properly? I'm guessing one would see drift, but are there more
efficient, quantitative tests to ensure thermistor board function?
Thanks,

I think it is about 3 khz. So I never go closer than 1.5khz. I suppose

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

Probably drift as you say. If the PLL Reference Oscillator Range test or VFO
Linearization doesn't go like it should I'd suspect the thermistor board first.

W5ALT says that the maximum bandwidth for a CW signal (assuming
you're modulating with a square wave) is 26 x wpm (http://
www.comportco.com/~w5alt/cw/cwindex.php?pg=5). So that makes the
bandwidth--at most--520 Hz. I would assume that the K2 shapes the
signal, so the bandwidth should be
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
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
assure good

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!
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.

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
