[Elecraft] Getting higher gain from input of line in or rear panel mic on K3

[Richard Ferch]

The audio input settings (source jack, bias, mic gain, etc.) are set and
remembered independently in voice modes vs data modes.

In voice modes, set the MAIN:MIC SEL, bias and MIC gain control to wherever
you need them for your voice and microphone. Set MAIN:MIC+LIN to OFF
(unless you are using the computer as a voice keyer).

Now put the K3 into DATA A mode. Set MAIN:MIC SEL to LINE IN, make sure
MAIN:MIC+LIN is N/A or OFF, and now use the MIC gain control to set the
LINE IN level. Typical numbers for this control are often in the range
8-12, but this is in series with the sound card's own Line Out level
control in the Windows mixer, so the two control settings interact
strongly. Between the sound card control and the K3's MIC control, you
should be able to set the audio input level in JT9 or other digital modes
to the desired 4-5 bars.

I am trying to get set up for JT9 in Data A mode; I am not getting
enough drive from the sound card to adequately drive the K3.

At the same time, the front mic is working fine (correct bias etc.) and
I don't want to lose this.
