[Elecraft] Possible issue with K3 Line In port?

[Don Wilhelm]

Paula,

Although you said 'it worked before', take a look at the ALC meter. 
With digital modes, you should have enough audio to drive it to 4 bars 
with the 5th bar flashing.  See the article on my website www.w3fpr.com.

Can you transmit in SSB mode?  If so, the K3 audio is fine and you can 
focus on the Line In or the soundcard output for the problem source.
