Re: [Elecraft] SKN - A Straight Solution - background

2005-12-20 Thread Thomas Miccolis


  Group,

  Jim  is  the  ONLY  "technical expert" recognized by the ARRL.  He can
  detail  the  actual  QST  issue which details this fact as well as the
  issue that his article on Field Day appeared (published author).

  Jim,  you  should research back to when there were multiple Field Days
  (duting  the  1930's?)  and document it here on the reflector.  SKN is
  important  because  many  people nowadays not only do not know history
  accurately  but  actually choose to revise it.  So it would be nice to
  know  the  exact year that the 4th of July event ceased.   Believe me,
  some  HAMs  only  know  BPL as an interference problem and NOT what it
  originally meant for decades!

  So here's what we all do:
  1) Operate SKN using straight keys only
  2)  Send  in  detailed reports of our operations to ARRL, with pics if
  possible,  listing  QSOs,  rigs/keys used, best fist, most interesting
  QSO,  etc. (Something ironic about using a $250 2004 digital camera to
  take  pics  of my 1945 J-37 key, bought at a junk sale for 25 cents in
  1965)
  3)  Mention  in  report  that  while  I/we have/use bugs, sideswipers,
  cootie  keys,  keyboards, electronic whoozis and watsatzs, on SKN I/we
  use straight keys only.
  4a)  Suggest  there  be  a  separate  "Bug Night" set aside. Maybe the
  original July 4th SKN date.
  4b)  Or  maybe  suggest  BN  and  SKN  should  run  consecutively, not
  concurrently - say, Dec 31 UTC is straight keys only, Jan 1 UTC is any
  nonelectronic  key.  Or  something  similar  so SKN retains its unique
  identity. You get the idea - tell 'em what we want!
  No  matter what the rules say, if we all use straight keys that night,
  it will remain Straight Key Night.

[Elecraft] Use of Lead (Pb) free SMD Components...

2005-12-30 Thread Thomas Miccolis


  Beware of tin whiskers!

  Lead-free  generally  translates to "pure tin".  If you do not want to
  risk tin whisker growth then you should solder dip or re-tin the leads
  of such devices with eutectic solder.

  No.
  If  you're  used to SMDs with lead plating, though, you'll notice that
  it  takes  a  very small fraction of a second longer for the solder to
  flow onto lead-free parts.
