Let's rewind this whole thing had have a rational discussion with some
meaningful technical content instead of all this subjective stuff
about "broadcast quality" whatever that means.

Bill, since you started it, why don't you start over again and begin
with a statement about what you think, i.e. your technical definition
of broadcast quality (in other words, audio frequency response by
frequency and no. of dB down from the peak level) and what you think
it should be, again giving us some numbers.  Maybe you think ham AM
audio should be 20 dB down at 100 cyles, nothing lower, with a gradual
rise of 15 dB to 3 kc and a gradual attenuation to nothing above 4.5
kc.  That's an example.  You may have a different technical
specification, but such a description would actually give us something
to discuss in a rational way.

The other vague and subjective statement is the "communicate using no
more bandwidth than necessary" thing.   Why don't you tell us what
that means to you in specific terms once again?  Otherwise such a
comment is needlessly provocative and contentious.
