How is AM stereo doing in the US?

Just about dead. Few receivers available except for some OEM car
radios, fewer and fewer stations broadcasting it.

But there are still more than 10 times as many AM Stereo stations as
there are AM stations using IBOC.

Let's say there are turly 200 AM stereo stations left... you are saying
there are fewer than 20 AM IBOC staitons.

Just the company I am with has 5, and there are already about 50 on the air
and another roughly 200 ordered and in construction.

Since IBOC does not coexist with AM stereo, it's over. The IBOC stations are
in major markets, and the AM stereos are generally X-band or oddball
stations with a penchant for suffering.

And as for "fewer and fewer
stations broadcasting it", you could say that about IBOC -- within my
listening range here in NJ, there are at least half a dozen stations
which tested IBOC for a few weeks or months and then gave up on it.

And which would they be? I don't know of that many in the whole country, and
the few that there are had problems with thier antenna system, not with IBOC
per se.


For example, iBiquity's web site lists 860 WWDB in Philly and 930 WPAT
and 1480 WZRC in the NYC area as current IBOC signals, but all of
these stations haven't transmitted IBOC in almost a year now. This
kind of track record does not inspire much confidence in the future of
IBOC, at least on the AM band.

The two NY stations have horrible DA systems, neither being optimized for
low-Q and bandwidth. And both are ethnic, not candidates for effective use
of IBOC when brokers bring thier programs on home made cassettes or CDs.
