[Elecraft] K3s audio problem

[Mark E. Musick]

Sid,
Why aren't you using the sound card in the K3S? Then your JT65 and PSK
software talks to the K3S sound card through the USB cable. Then you do not
need external sound cards or connections to LINE IN, LINE OUT or the front
panel MIC jack.
I operate AFSK RTTY and this is how I have MTTY, N1MM and Writelog set up.

Sid,

In that case, you would set the MIC SEL menu to FP.L as you have it, and
feed the soundcard output to the mic input.

Note that this has nothing to do with your headset that you use for SSB.
Use DATA A mode rather than SSB because that data submode sets compression
to 1-1 and the TX EQ to flat.  That setting is independent of any settings
you may have for SSB.

I am just curious why you have not connected the soundcard output to the
Line In jack on the back of the K3 - it is not only more convenient when
switching between SSB and data modes, but it offers transformer isolation
for the soundcard lines.

In either case, adjust the audio level to produce 4 bars solid with the 5th
bar flashing on the ALC meter - that is the "no ALC" point for the K3.  Set
the power desired with the K3 power knob.
Ignore the "internet" advice to adjust the power using the audio level -
that does not work with the K3.  Adjust the power level with the power knob.
