[Elecraft] K2 S/N 4787 Build In Progress

[Jim Harris]

Hi to everyone,

K2 s/n 4787 was received yesterday (3/2/5) at about
1:20pm via UPS.  At about 15 hours into the experience
I have the control board and front panel complete and
just starting the RF board.  Several comments.....

How did they squeeze all that into one box!

On the control board I mislocated one capacitor.  All
resistance measurements were fine.

On the front panel board while trying to add SSB
components after the fact I managed to slightly burn
the edge of a push button.  Wish the instructions had
mentioned to put the low SSB components in before the
higher and vulnerable parts were added.

On both completed boards an IC ending in "06" on the
parts list actually ended in "16".  I'm reasonable
sure I got them right by a process of elimination.

I'm inventorying each board as it is begun.  There is
not enough space on my work bench nor do I have enough
spare parts trays to do the whole inventory at once. 
I may be missing 2-3 parts on the RF board.  But, I've
learned already to wait and see if they turn up in
another bag.  The torrids cores were confusing at
start but seem to have worked out okay.  At this point
capacitors for the RF board are a wild blur.  I'm sure
I have not correctly identified at least a third of
them.  Many numbers on the caps are simply not in the
parts list.  If anyone has a good way to ID them I
would be pleased to hear from you.  Measuring them so
far has proved somewhat futile with a simple DVM with
a capacitance measuring function.  Several resistor
packs have not had the right part numbers.  So far
I've been able to ID them by measureing them.

My impression so far is that there are components of
some of the accessories to be installed on the three
main boards but when and sometimes how is not always
clear.

With the kit I purchased an Elecraft/Heil MD2
microphone.  Apparently a resistor is to be added on
the back of the mic plug on the front panel board.  I
have two other Heil mics.  Can they be used on the K2
with or without this resistor?

I'm trying to take a few pictures as things progress. 
I'll try to find a way to post them when finished.

Thanks for listing guys.  This is quiet an
experience!!

Jim, AB0UK
