I won't deny it!

Now, if you want my honest assessment, I find the whole thing fraught with
ethical questions.

What if someone isn't listening to the radio when the message is
broadcast? What about the people who don't live near railroad tracks?

If this thing is to *actually* work, it would have to be space based. Work
with a database of the frequencies in use in the affected areas. broadcast
on them as the need arises. FM will be easy. AM will be some more work. Of
course you'll still have to deal with the people who aren't listening at
the moment!

Of course if it just a research project to burn up some money, then *that*
is a different subject altogether!

Space-based wouldn't work. You can't get a spot footprint small enough on
the earth's surface to make this do-able. Iridium comes about the closest,
but would you put up a constellation to provide the footprints and not use
it 99.999999999% of the time? :-)

Cheers.
