[Elecraft] [K3} Why route microphone through a sound card?

[Pete Smith]

The compression control and TX EQ work normally.  Gain has to be set 
from the menu, for the Line In jack.

There are a couple of reasons why I do it this way. Mainly, it's because 
I need to reset my Run F1 message "on the fly" when operating split on 
the low bands.  Say I want to operate 40m at 7130, listening 7065 - with 
N1MM Logger I hold Ctrl+Shift+F1 and record a CQ specifying that 
frequency.  Then if I have to move my listening frequency again, I 
rerecord as I transmit.

It's also convenient to be able to set my "live" audio and the recorded 
audio to the same level. and thereafter adjust both with a single 
control.  I do this with a dummy load and I'm all set. Thereafter, if I 
need to adjust, I do it with the master playback gain of the audio mixer 
on my sound card, and needn't touch the radio.

And finally, putting both live and recorded audio through the same 
channel helps to make sure they sound the same, even if the sound card 
adds some white noise or unintentional shaping.
