As to AM in Carlsbad, you are at the fringe of the AM signals
of the San Diego HD AMs, so dropout would be likely on a bad
receiver. The fact is that SD does not even have an AM that
totally covers the market with a usable signal.

2nd model maybe, not second generation.

First generation used several separate chips. Second, starting
with the BA Receptor, used an integrated chip, third generation
coming in next few months.


Nope. All radios so far are using general purpose IC programmed by
EPROM to run the Ibiquity application.

I'll let you know when an IC that specifically designed for IBOC
comes around.


Gen 1 was a bunch of chips... gen 2 is one EPROM (which in general
parlance, is a chip). Gen 3 includes the Samsung and other "radio on
a chip" products.

Gen 1 was the Pioneer car radio nearly every CE of an early HD
station had.


The program is stored on an EPROM it does not run on an EPROM. An EPROM
is just a memory element. Since there are no IC elements designed for
IBOC yet you need to use a general purpose DSP IC that can do many tasks
depending on how you program it. These part don't have permanent memory
so you use a part like an EPROM to store the program.

An IC designed for IBOC will not need an EPROM.
