Sean,
U8 is seldom faulty. Check your soldering - refer to the Soldering
tutorial on the Builder's resource page at the Elecraft website if you
have questions. If suspicious, re-flow the soldering with a hot iron
(750 to 800 deg F). The solder should flow out to an almost invisible
edge on
Hi all,
I'm building my K2. I've just got to the step where everything gets
assembled and tested for the first time, and when testing the sidetone
I'm getting nothing.
I've set the K2 to edit St L and varied the value from 0 to 255,
checking the voltages on U8. Pin 1 is 0v for all settings, an
Paul,
That is in fact perfectly normal. The reason is that the AGC and RF
Gain control are using the same voltage to control the gain, and the
S-meter responds to that voltage. You will do the initial S-meter
adjustment during your Part II alignment.

I have completed part II of the assembly of my K2 and I am about to move on to
part III (alignment and testing of the 4 MHz oscillator, VCO, BFO, etc.).
Everything has gone well up to this point but I did notice something that seems
a little bit unusual. Is it normal for my bargraph to light up

You may want to add the header for the AUX RF before you mount the heat
sink on the K2 RF Board, and that part is included with the KPA100 kit.
All other changes or additions are easily accessible by removing the
bottom cover. Removing the heat sink is not a nasty chore, but is more

Hi all,
I just completed the control and front panel board builds yesterday. The kit
is really remarkable, even the mounting of the LCD and diffuser basically
went off without a hitch. I did have a capacitor left over at the end of the
front panel build. Went back through the manual and saw the on
It took me two and a half days to build my 2nd K2, about 30 hours total,
then some time spent doing the alignment and adjustment, then I built most
of the options in the next week.
The first K2 took about 40 hours, but I think they improved the manual over
time.
The building is VERY fun and add
Jon,
The KAT100 can be used with the basic K2, there are 4 internal K2
signals that must be routed to the KAT100 for it to function. So the
base K2 MUST be equipped with the KIO2 or a suitable substitute (see the
websites dealing with the external KPA100 for the substitute - if it

Subject: RE: [Elecraft] K2 Build Sequence Question
I can't comment on the KPA100 or KAT100.
Your intentions of an incremental build make sense to me.
I'd make sure that the KAT100 will function as an autotuner with the basic
10 watt rig (I'

Others on this forum with more K2 experience than I will chime in, I'm sure.
I've just built one K2, and it's the QRP version.
