Absolutely, LO. I'm sure you've done what I have on numerous occasions over the past five years - which is, a one-on-one quiet face-to-face with a sales engineer. I haven't spoken to a single one who thinks HD is a valid, much less a great, idea. After a handful of initial sales, they pretty much hate it, because it creates perennial problems.
They roll their eyes and say, the Home Office makes us sell this stuff. It's crap. Every gear manufacturer has a support department where the engineers do nothing but deal with incessant problems, complaints and issues about HD. The system generates more grief than every other product the companies sell put together. And half the time the problems originate with iBiquity, not the transmitter makers, so the poor station engineers get bounced back and forth between the parties as the manufacturers and iBiquity blame each other for problems.
Sales engineers will also tell you, in an unguarded moment, they haven't sold appreciable HD stuff in months if not years.
