Dear Frank,

I have never heard an IBOC broadcast and, as I rarely DX on the MWs, I
have not personally been bothered by spillover.

However, it seems to me that while IBOC is probably fine for the FM
broadcast band, either as an adjunct or even possibly the only
broadcast method on that band in the future, it, and all other known
digital transmission schemes, ought to be totally banned off the MW
band. This band (and its analog broadcasting method) is the only
reliable means of communication within the United States; it has the
two advantages of long-distance reception capability and a huge
installed base of receivers. (Relatively few people own shortwave
receivers.) This, of course, would be invaluable in the case of any
disaster, natural or man-made. No digital scheme has these advantages.

I should like to see the MW band expanded, say, from 510 kHz to 2000
kHz (and yes - I know this would eliminate an amateur band). Some of
these frequencies could then be restricted to clear-channel broadcasts,
perhaps one station each from the twenty or so largest cities all
around the US. In the event of a catastrophe, the desirability of such
stations is self-evident.

My $0.02 anyway.

Best,

Joe
