Tom,
You have to use DATA A with a soundcard program such as HRD or MultiPSK.
Here is what I do:
Turn off Tx ALC in menu. I use VOX instead of the PTT line. Adjust VOX and
ANTIVOX as needed. Adjust LINE IN and audio output from soundcard so that
you get the power output that you want to use (no more than 50 watts with
the 100 watt K3). Use the K3's power meter to adjust. With my HT OMEGA
Claro+ soundcard, I use a LINE setting of 3 and a low output on my soundcard
(about 1/3 from full output). It doesn't take much. Of course you will see
no ALC reading, because it is turned off. The K3 will automatically go into
Tx when it detects audio input... why use PTT if your don't have to. Use
1500Hz center frequency with software, and adjust bandwidth as needed. You
can go as low as 50Hz with PSK31.

Subject: [Elecraft] Help with PSK
I am trying (and failing miserably) to set up my K3 to work PSK31 mode.
I am using a Microham USB Microkeyer II and my normal Logger 32 software
which I have used for aged with my MP running very fb.
The outgoing tones from my K3 dont "sound right" and a near neighbour says
my signal is very bad
unreadable and very broad.
In the K3, I have the compression set to 0 the mike gain set to 0. I
am in Data mode and using DATA MD have PSK D showing - 31 bps.....
My K3 ALC meter is still showing almost full ALC (according to the meter)
with almost now poer output (turned right down).
I have the TX knob on my Microkeyer set at zero and within Logger
soundcard - psk window, have the output set right back, well below the
settings for the MP!
I am receiving PSK no problem at all. The radio is connected to my
computer via the serial port on the rear...
I can run RTTY FSK without any problem whatsoever.
I think i need a little guidance here...
