[Elecraft] Low Line-In level

[Don Wilhelm]

Dragan,

Since you have tested 2 computer soundcards with similar results, I 
suggest you contact Elecraft support for further clues to 
troubleshooting and resolution.

It still sounds to me that the computer speaker level may be too low for 
some reason.  If you can get the normal 5 to 7 bars of ALC meter with 
the microphone, then you should be able to get 4 bars solid with the 5th 
bar flashing in data modes.

Do you have bias set on for the mic connection? - bias should be off. 
If it is ON, then the bias voltage may be reducing the output of your 
soundcard interface.

73,
Don W3FPR
