Hi All,
My K2 will be in the post soon. Meanwhile I have been avidly reading
in readiness for the build. One mention of this mod refers to C72,
many others like Stan & Jim refer to C71. Checking the schematic for
the KPA100, C71 is listed as 0.0018uf decoupling RFC3 to ground and
C72 0.01uF decouples the gate of Q6 if I read it right. Can someone
please check this out before I need to get a solder sucker out!!
73 to all, thanks for the excellent reflector and those at Elecraft for
the excellent manuals. Looking forward to joining you with the build
and on the air.

Hhmmm. This is the second time today that I have seen the C71
reference on
the KPA100 board. I am in the process of building my KPA100. Do I need
to
replace this cap now before I go any further? I don't have a DSP unit,
but
will be adding it later. I would rather do the mod now than have to
take it
apart and do it later. What do ya'll think?

Subject: [Elecraft] Re: Which Mods are applicable?
Jim,
I have just finished K2 #4687 with KPA100, DSP, 160M, SSB and NB. My
kit
came with all required mods already in the parts package. All I
needed to
do was to update the construction manual with written notes found on
the
included Errata sheets. Elecraft included one Mod bag of parts for
either
the DSP or KPA100 (I don't remember which one) which I THOUGHT needed
to be
installed, but after realizing I was replacing a capacitor with the
exact
same capacitor (I'm slow sometimes), I realized the corrected parts
were
already incorporated into the regular parts inventory. The only part
I had
to replace which can be called a mod, was C71 in the KPA100. As luck
(or
incredible planning on Elecraft's part) would have it, the .1uF
capacitor
needed for C71 was a spare left over from one of the other accessories.
My point is: I wouldn't worry about those "optional" mods until you
get the
rig together. Elecraft has done a great job of getting an up-to-date
kit in
your hands so that you don't have to worry.
Have fun!
