"Amateur TV" or SSTV is dead, replaced by much newer technology

Okay, John, I understand completely where you are coming from. I
ask for no more.


It is interesting that "John Smith" made the same error that Len made
some time ago. Amateur TV and SSTV are not at all the same thing.
For that matter, neither are dead. ATV is quite alive and SSTV is
simply implemented differently, via the use of soundcards.

Correct. SSTV is hardly TV at all, being still images. And ATV is
indeed the transmission of moving images, and there is a very good
reason that it is at UHF frequencies.
