I can't offer any examples from the amateur radio market for the simple
reason that I'm not licensed for HF operation myself, not yet having
passed the Morse test, and thus have had no reason to look for them.
However, there *ARE* suchlike systems in use on HF in the commercial
world, most notably the various WAN-ethernet cards that operate on the
HF bands at various frequencies. My brother has one in his computer that
he uses to connect to his Works network, and it appears to operate with
a low power signal with a 3 MHz bandwidth centred around 25 MHz.

Is it also necessary to have exactly the same FIRMWARE on those carsd at
each end? If so, then every time SCS release a new version of the
firmware, everybody has to buy t to remain online...

Your mis-information didn't help.
Best wishes from Riley.
