[Elecraft] K3 data mode fail

[Don Wilhelm]

Skip,

Make certain the K3 is getting audio into the Line In jack.
Pull the speaker or Line Out cable from your soundcard and plug 
headphones or amplified computer speakers into that soundcard jack.
Then do a TX from your software application.  Do you hear any audio 
tones?  If not, check the computer/soundcard.

If audio there, plug in the cable to the K3 Line In making sure the 
plugs are fully seated on each end.  You could have a bad cable.
Since you have good audio to the computer on RX, swap the two audio 
cables between the soundcard and the K3.  If you have an OK waterfall 
display, the cable between K3 Line Out and soundcard line in (mic) is 
working.

If you still have problems, contact support at elecraft.com for further 
analysis.
