[Elecraft] K3s USB sound card problem

[Richard Ferch]

If checking and if necessary correcting the output sound device selection
in MMTTY doesn't solve the problem, here are a few other things to look at:

The Windows sound card level setting on the USB audio codec (playback side)
The K3S's MAIN:MIC SEL setting while in AFSK A (it should be LINE IN)
The K3S's Mic gain setting while in AFSK A
The K3S's MAIN:VOX GN setting while in AFSK A (if you get an indication on
the ALC meter but it doesn't trigger PTT)
