Re: [IRCA] [NRC-AM] Re: Another perspective on AM IBOC, from thebroadcasters' mailing list

["Stewart, Joseph R" <RandyStewart@xxxxxxxxxxxxxxxxx>]

I've had a Boston Acoustics HD radio at home for a couple of months now,
and haven't listened to it since the first week we got them at KSMU.
None of our local AMs have put HD on the air, and none of the FMs that
have it--my station included--is doing anything interesting with the
secondary etc. channels, or indeed anything at all.  We will actually
program our secondary channel with all jazz (I think), but it hasn't
happened yet.

But since there are no local AMs running HD, my only recourse has been
to try and decode HD audio via skywave... and even with stations
producing a virtually city-grade signal in analog, it's been no dice
here so far. I get the visual ID, but no digital audio.  Obviously no
one in this metro area (Springfield, MO) currently has much reason to
want to "upgrade" to HD... slim pickings on FM--only 3 local stations so
far are even broadcasting in HD on the FM band--and NO AM stations
running HD (nor, from what I've heard, do they have any intention of
doing so in the near future).

I kinda sorta hate to admit this but...

I was at WPLN-1430/90.3 this morning.  (volunteering for the pledge
drive)  As usual, after my shift ended I ended up chatting with the
engineer and the station manager.  They played some recordings they'd
made of music, played on WPLN's HD AM station, as received on a JVC HD
car radio.

It really, really did sound like FM.  I think the spoken word
programming that's been on WPLN-AM when I've listened in HD simply
didn't adequately demonstrate what HD AM can sound like.  (and WLAC, the
other HD AM station around here, really never has sounded quite
right...)  

I'm coming to the impression that some of HD AM's shortcomings are
indeed actually those of receivers - that if some decent receivers come
along, it could actually work during the day.

That doesn't mean the nighttime problems are any less of a problem.
