We bought a dozen or so average consumer radios, from a walkman to a boom
box to a clock radio, and whatever is in between. On every one, the music in
analog sounds as good as it did before, and switching the IBOC on and off
produced during several days of testing no significant differences on
average radios.

Your experience is precisely the opposite of a 50kw (oldies) music
station with which I am familiar. It turned off the IBOC because of
unacceptable adjacent channel interference issues. To the great
surprise of the PD, who believed as you do that no one would notice
the difference in the analog bandwidth, he immediately began getting
calls from listeners during his airshift saying the sound of the
station had improved greatly, and praising the station for whatever it
had done to make it sound so much better. AFAIK this station has no
immediate plans to resume testing of IBOC.

I personally have heard this station with IBOC operating and found the
analog signal nearly unlistenable on a narrow-band standard GM car
radio.

Two stations here in the New York City market (WPAT-AM 93 Paterson and
WZRC-AM 1480 New York) were also trial-running IBOC, in addition to
WOR-710.

The test didn't last for even a month.....

Maybe there's something to do with the processing or what. Who knows.

All I know is, when I'm listening to WOR with IBOC going, there is
also a hiss in the audio - almost like tape hiss. And this is on a
medium quality digitally tuned walkman, so I know I have the station
on the dot.

However, on some realy really low-fi clock radios and pocket radios
the station sounds 'OK' sort of...not including the hissing going down
all the way to 68 and to 74 (where it's sort of overridden by the
splatter from the stations at 66 WFAN and 77 WABC respectively.
