[Elecraft] K3S & PC Win10 Soundcard

[Don Wilhelm]

Bret,

If you look at the soundcard in the Windows Sound properties, what us 
listed for output when only the K3 is connected? (Likely Speaker)  Then 
plug in the BT RXc - is the same output still listed and the headphone 
added, or did Speaker get replaced with Headphones?

Some soundcards will not allow simultaneous Speaker and Headphone use.
Usually when the front panel jacks are used, the rear jacks are turned off.

WSJT-X does not use the soundcard path for TX enable, but the serial 
port connection.

Apparently your BT RXc is turning off the audio to the K3 for some 
reason - this is a computer audio path problem, not a K3 problem.
