there is no requirement that anyone listen to any broadcast radio. with the
rapid growth of satellite radio there are even less people listening to
either am of fm broadcast radio. add those who listen to cd's or dvd's and
you get even less.

There are systems that are used for local road emergency notification, the
560khz one comes to mind, something along those lines would be the best bet,
and add in signs on the backs of vehicles. i guess the real question is,
what are you trying to do by overriding local broadcast stations? and over
what size area?

Am I way off base here, can any antennae, fractal or other, or any AM

All comments appreciated.

The things that pop into my mind are why AM rather than FM, which tends
to
be more local, and do you intend to 'over-broadcast' only the local
channels
(how many?) - I assume you intend to make the channel(s) selectable - or
the
entire band to ensure you get everyone?

The issue of selective vs full range broadcasting is a matter that has not
been decided either by client, company or possibility. There are plusses
and minus' to each.

Selective would entail less power but we are being told power of the fire
engine is not an issue.

Assuming that there is a commercial
AM broadcast station in the vicinity (what, 10 miles? 20 miles?) you are
probably going to be flat out getting a mobile rig to ride over it. How
do
you intend to do this?

Cheers.

lol Good question, Ken. Any suggestions?
