[Elecraft] Problem with Test TX Data and ALC

[Don Wilhelm]

Carl,

I figure you are using the K3 LINE IN jack, and when you used it on the 
KX3, you used the MIC jack.
The Line In needs a much larger audio signal than the mic level that 
your SignaLink is providing.
There is a jumper you can change in the SL box to increase the audio 
output level - look for it in the SL manual.
