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.
