[Elecraft] Day 1: Fried something already?

[Don Wilhelm]

  Owen,

That pin numbering is correct - it is just like an IC.  From the top, 
position the white bar to the left, and pin 1 will be the leftmost pin 
toward you.  On the bottom, you can usually identify pin 1 by the 
different shaped solder pad.  Normally pin 1 is round while the others 
are rectangular.
