It does mention tin whiskers.

(All recent legislation has them, although the press tends not to 
mention them.)

[Elecraft] K2/K3 Scientific Attention to Detail

2007-10-19 Thread Bill Tippett

http://www.theworldlink.com/articles/2007/10/06/news/doc4707c03901b23958789121.txt

The EU's decision was irresponsible and not based on sound science,
said Joe Smetana, a principal engineer and tin whisker expert with French
 telecommunications equipment maker Alcatel-Lucent SA. We're solving
a problem that isn't and creating a bunch of new ones.

A good example of well-intentioned environmentalists and politicians
ignoring science...the law of unintended consequences strikes again.  Thank
you Elecraft for staying ahead of the game (by not allowing lead-free solder
use in the K2).

From W0YK's comments on the Sprint using two K3s in SO2R:

Prior to this, with the K3 in one ear and another radio
it the other ear, the K3 was strikingly better to listen with.

It only sounded like the signal was in one spot because I had
the AFX Binaural feature turned on.  This effect was accentuated
by the much lower noise component in the audio of the K3, even
on 40, 80 and 160.

With the K3, my brain needs to be re-trained to copy CW without
the background rumble of noise and distortion and extraneous
artifacts that I hear with other radios.

Thank you again Elecraft for your attention to detail re
IMD, BDR, Phase Noise, AGC, etc.  Attention to details, using
scientific metrics rather than marketing perceptions, DOES make
a difference, despite what other manufacturers might have us
believe.  When the K3 hits full production capacity, I predict
other manufacturers will wonder where their orders went.

73,  Bill  W4ZV

That's the EU in a nutshell. For another example, look at all the
effort made to force Microsoft to release a version of Windows with no
media player in it. Which nobody wants...
