[Elecraft] K2 and Digital Modes

[Don Wilhelm]

There is no known problem for using the K2 with any of the soundcard 
interfaces as far as I know.  Most interface boxes allow for configuring 
  to the proper microphone cabling (even if they offer special cables). 
  And the K2 can be configured to use most any microphone wiring scheme.

The K2 audio that is fed to the interface card is quite another 
decision.  The headphone jack and the external speaker jacks are easy 
candidates, but will vary with the setting of the AF Gain control (easy 
enough to adjust by looking at the waterfall display background color), 
but if you want an independent fixed audio output, my K2 Fixed Audio 
board is one solution.  See my website > http://w3fpr.qrprqdio.com
(I no longer have kits, but I still have a few boards available).
For the K2/100 the board can be mounted between the front panel and the 
control board.
