[Elecraft] K3: 'Line In' problems

[Don Wilhelm]

Jason,

Since you can drive the K3 from the mic input, I am wondering if you 
have enough signal available to drive the K3 LINE IN at its expected level.

Do you have an in-line attenuator in the cable you are using at the K3 
LINE IN?  Or are you using an interface box that has an internal 
attenuator?  If so, you may not be getting enough signal into the LINE 
IN jack.

Try connecting the Line-out from the soundcard directly to the K3 LINE 
IN jack using a straight stereo cable.  The K3 does not need any 
interface box or in-line attenuator.

73,
Don W3FPR
