[Elecraft] K3s USB sound card not receiving MMTTY audio

[Mike Dodd]

Aargh! Aargh! Aargh! (Sound of head banging on desk.)

The problem was that I did not have the K3s set to use the line input! 
I.e., MAIN:MIC SEL menu entry was not set to LINE IN.

I feel stupid for overlooking this setting, but honestly I don't 
remember doing it in the past when setting up for other RTTY contests, 
or switching back to MIC afterward. I need to check MMTTY and N1MM to 
see if either sends any commands to the K3 to do this automatically.

To make matters worse, I have a text document that shows connections and 
settings for the K3, but it didn't mention the MIC SEL menu entry; it 
only said to set the MIC (line) level. I completely missed the implied 
line input selection. You can bet that is now fixed!

So, problem solved. THANK YOU to everyone who offered suggestions here 
and via private email. I hope I can avoid this embarrassing situation in 
the future.
