Hi Elecraft K2 Experts  :)

I've started building K2 # 5422, and have finished
Control Board.

Couple of dumb questions - might keep my "ship" on
course:

1.  What is "numbering convention" of standard IC
packages - starting
with Pin 1 - does numbering go down that side and wrap
back on other
side, back to pin across from Pin 1?  (I know this is
basic, but .....)

2.  What is the "lettering convention" of standard
TO-92
transistor packages - from front flat side? 
(collector,
base, etc.)

3. Measuring all the ohmeter resistance checks at the
end of Control
Board section - I'm getting some resistance readings
much less than
manual's table values?  (I'm using an analog meter VM)

I might try to send Control Board (# 5422) back to
Elecraft's support
desk, for a checkup of this first board - for peace of
mind.

It took 4 days, part time, to build Control Board.  It
"Looks" good.
