[Elecraft] K2 #3547 done! (and a question on K2's and immigration)

[akern@haverford.edu]

K2 # 3547 is completely done.  KPA100, KAT100, KSB2, K160RX and KDSP2 are 
all up and running.  I just did the DSP today--what an AMAZING
difference.  I can't believe how well the filtering works.  I showed it
to a few of my buddies here and now they all want to build K2's!  To the
guys at Elecraft--I know you're reading this--a job VERY well done.  I
couldn't have had more fun building the rig.  Not to mention that you
have the best customer service ever!

On an unrelated note, I am leaving for South America in 6 days and am
becoming preoccupied with how I am going to carry the rig through
customs.  (Sorry, this is not a technical question.)  I'm all set in
terms of the mechanics of it--I have a padded backpack and all that
stuff.  It's the paperwork and immigration officials that have me
worried.  I'm going to HC land first, and although I won't get my
reciprocal license until I'm in Quito I do have an IARP and will have the 
Ecuadorian consulate notarize my FCC license.  What I am really concerned 
about is the possibility that I might run into some junior level customs
officials who are not up on their ham radio and for whatever reason think 
I am suspicious.  Any thoughts from people who have already carried their 
rigs internationally on how to best get through customs checkpoints?
Should I proactively open up the rig and present my paperwork, or just
walk through and hope they don't pick me out of the line?  Also, should I 
bring the gel cell battery (sealed) in my carry on or check it through?
Any advice would be appreciated.
