[Elecraft] Using external sound card for digital modes

[Tighe Kuykendall]

Maybe your MIC BTN setting, page 35 in the manual?

I was struggling a little with digital modes on my KX3.  After trying 
several things, I picked up a USB Traveller from G3LIV 
(http://www.g3liv.co.uk/).  Has keyed PTT via USB, isolation 
transformers, and controls for RX/TX levels.  It's small and packs well 
for portable use and is USB powered.  I've used it with the built-in 
sound on my MacBookPro as well as a TASCAM US-2x2.  For me, it was money 
well spent.  Customer service from Johnny is awesome as well.
