You can't use your radio as an excuse. There are simply too many of
them that respond the same way. In my mind, it's simply bad
engineering to allow a signal to be polluted that way. Even if you
ignore the effects on listenership, it's hard for me to understand
how engineers can accept and make excuses for what I hear - for what
many of us here hear. As more stations install the hash generators
the worse the band will become. It doesn't take exotic, expensive
equipment to see how the AM band, and, possibly, the FM band will
suffer in an effort to join some mythical revolution.
I honestly hope that nighttime IBUZ operation will be authorized soon
enough to prevent complete destruction. The grand HD Dominion was
created to obscure the serious technical issues. Will $200 million in
promotion money make the technical issues either go away or become
palatable to listeners? How many engineers are members? The names I
see are sales and Wall Street-driven executives without a technical
clue. That, in itself, is strange to me, since these are the people
who stand to lose the most from bad technology. Of course, most of
them will have been fired long before analog goes away. They'll just
get too old (more than 40) to be relevant to whatever generation is
ready to pop up. Most are there, already. They'll be fired by a new
20-something boss.
From a programming standpoint, I believe it'll kill AM. The jury is
still very out on what effect the artifacts on FM will have on TSL.
We won't know that until receivers are replaced. I suspect that those
who went to CES will come away with the feeling this is feeble
technology that will be replaced well before it finds its market by
something far less destructive.

I spent a couple of months with an IBUZ receiver. It ain't no
revolution. As you discovered, a simple AM radio is all you need to
prove it doesn't work well.

At this point a hairshirt is more appropriate.
