[Elecraft] K2 and data modes

This works but it is very "soundcard dependent."  If your soundcard 
has limited input gain or is particularly "noisy" the direct connection 
is marginal.  The "smart" solution is a combination of J5 and a 20 dB 
buffer like the W3FPR/N0SS board. 

More recent interfaces - microHAM DigiKeyer and microKEYER II - include 
low noise preamplifiers to work with fixed level audio sources as low 
as 50 to 100 mV (e.g., J5 in the K3 and the fixed level outputs in many 
YaeComWood radios).
