On my PC, I have several programs concerned with reception and

No, the programs can decode Morse code.

Only those programs which are designed to decode Morse code will decode
morse code. Some of the other programs are designed to teach Morse, and
will not decode Morse code. Most of these will accept a text file and
translate it into audible Morse. 50 years ago, when I was trying to
learn Morse, such facilities had never even been dreamt of! For
beginners, these programs are far more user-friendly than trying to find
slow Morse transmissions on the SW bands.

They probably CAN NOT DECODE other
trinary encoding, whether it's sent using CW (carrier on/off), MCW (tone
modulated carrier on/off), or FSK (frequency shift keying).

As long as the PC sound card is fed with beeps and boops which
adequately resemble what I mistakenly call Morse code, the decoding
programs make a valiant attempt to decode it. For convenience, you can
simply record the beeps and boops as an audio file, and decode it later.

You keep confusing the encoding of the data with the transmission medium.

But I have said absolutely nothing about either the encoding or the
transmission medium. You are mistaking me for someone who knows more (or
better) than I do.
