Hi Mike,

> Can a Kam KPC-3+ used for VHF packet work?

Your TNC should work well ... monitor on 145.800 and 145.825 MHz with
PASSALL = ON in the TNC.  The 145.825 frequency is the one usually used for
spacecraft APRS packet but the ISS has been on 145.800 up & down for
digipeating this past week.

While the syntax of the commands you type into your TNC may differ from the
examples I used for an MFJ TNC-2 you can likely get on the air with the
settings I have summarized at:

ISS digi is workable with less than 5 watts and a 2M vertical. PCSAT is
workable when its in full sunlight and I generally have better luck with a
small (3-element) 2M beam on that bird.
