The modulation scheme used for DTT in USA might help keep the
art of working with radio waves, how they propagate & most importantly
how to best receive them alive.

Things like SWR become important, even for more robust methods
like on satellite - stuff that the AM/TV dBuV-mindset crowd will have
to work to get their heads around.

Yes, SWR on receive.

Big improvements in demod chipsets over time, but there is ultimately
a limit to what can be done to work with what's coming down the
feeder.  Advances in technology tend to have dumbing-down effect,
but all things digital have bits that are better approached analog-like.

There is more to the trend of one-zero-off-on-that's-all-I-need-to-know
which interestingly us retro-hobbyists seem to have a better
understanding of sometimes than the "industry".
