[Elecraft] K2 and Digi Modes

[Doug Faunt N6TQS +1-510-655-8604]

Yep, the board shown on your site is the one.  I used a miniature pot
(1/4" square) that fits the board pattern, with the adjustment screw
parallel to the board so it can be reached from above.  I used an 1/8w
resistor, miniature 3 x 5mm electrolytic caps, and an 1/8" standoff to
mount it.  When I get a camera again, I can take photos of the board
in a K2 since I have to replace the earphone jacks on both K2's.

   Doug,

   Since the boards have the pot, they are definitely from my batch - Tom's 
   had two fixed resistors in place of the pot which worked well because 
   the level could be adjusted with the soundcard controls.  Those who get 
   your boards should look at the instructions on my website www.w3fpr.com.
