Paul,
Some programs are capable of sending a Video ID using Hell, so, you
can read the ID as a text preamble from the waterfall.
MultiPSK also does send a RS ID using some codes sent as an MFSK

I guess that RTTY, AMTOR, etc. That's up to my friend, I will pass this
to him.

That depends on what you’re interested in doing with your PK-232.
WinWarbler supports your PK-232’s CW and RTTY modes. You can run RTTY
