[Elecraft] K3 #1456 - data modes setup

[Bob Towers]

Well, the K3/100 kit arrived on 18th August. I ordered it on 31 March 
and was expecting September delivery, so it was a pleasant surprise to 
get it early.

The K3/10 is built and I've connected it up to my soundcard (Aureal 
Vortex) on my PC via the LINE IN and LINE OUT jack sockets on the back 
of the K3. The connections to the soundcard are line out and line in 
respectively. My digital mode software is MixW.

I've come across a problem: the LINE IN and LINE OUT levels appear to be 
pretty low. I need to set the K3 LINE OUT level well above 50 before I 
can see a trace on MixW's waterfall, even with the soundcard's line in 
level set to maximum. I also need to set the K3 MIC gain above 50 before 
I get a decent level of drive; even at 70 the ALC level doesn't even 
register.

I have previously used this soundcard without problem with fixed level 
inputs and outputs from my TenTec Argonaut V, so I doubt whether the 
problem is with the soundcard.

OK, I could use the soundcard MIC input and speaker output instead, but 
I guess the impedances will be all wrong.
