[Elecraft] K3 Audio from RS232 connection?

[Bill Frantz]

You can use the line in/out connectors in the back of the radio 
and a "sound card" for your computer. USB sound cards are 
available inexpensively from Amazon. I have one for my KX3 which 
I think cost about $5.00. You may need to install a pad to lower 
the signal level between the line out on the radio and the Mic 
in on the sound card.

In an ideal world, you will get the the RJ-45 connector 
repaired, either locally with someone who can re-solder the 
surface mount connector or by getting it repaired by Elecraft.
