Rich,
I have read Don AA5AU discussion on this and this is the next thing to
do now that I have my two K3's wired up for FSK RTTY. I can do this as
part of the process in getting ready for the ARRL RTTY Roundup. I have
a 24 inch LCD monitor screen so hopefully I can find room. Thanks for
the excellent suggestion and information.

The PK-232 has a cable from it to a serial COM port port on your
computer which you need to set up in your software, in my case Writelog.
That is all you need between the PK-232 and the computer. There is
absolutely nothing hooked to the computer sound card.
Actually, if you want the best of both worlds you can run an audio cable
between the PK-232 or the radio and the computer's sound card line in jack,
and use MMTTY as a second decoder. If you have room on your computer
monitor's screen, you can watch both decoders (PK-232 and MMTTY) running in
parallel - sometimes one copies when the other doesn't. I haven't done this
with the K3 yet, but I have used this trick with other radios. You can
either use a Y-connector at the radio or the PK-232, or if you connect the
radio's line out to the PK-232's 5-pin connector (J4), you can connect a
cable between the PK-232's phone jack (J3) and the sound card (the audio
inputs on J3 and J4 are connected directly together, so in effect there is a
Y-connector inside the PK-232).
In addition to giving you two decoders, this also lets you use MMTTY's
crossed-ellipse X-Y tuning display, which you may prefer to the PK-232's LED
tuning indicator. You can configure the MMTTY X-Y display to rotate in the
same direction as the radio's tuning knob, which seems to simplify the
hand-eye coordination process while tuning in signals.
