I think you will find that the FCC has the FINAL call on frequency band
usage. I can't see them authorizing such intrusive use of the normal
broadcast bands, especially after the broadcast industry gets wind of your
proposal.

They got wind. Intrusive? Matter of subjectivity. A 30 sec message that
envelopes a 3500 sided square?

From a technical standpoint, broadband transmission of a signal is not hard.
A simple VFO sweep of all the normal broadcast bands is all that is
required. Obviously, the appropriate modulation techniques would have to be
used for each band.

That's the way we see it, more or less.

Another approach would be the use of a local (LOW power) sweeping UP/DOWN
converter. In this method, you could transmit a specific (authorized) signal
from the site. This signal would be received and detected by a local
receiver. This information would be used to modulate and rebroadcast the
signal within the vehicle. However, this would require onboard equipment.

Which mat make this impractical in the short run but there has been
discussion about mandating this type of installation. I have my doubts but
then we have seat belts and airbags.

I still think that your biggest hurdle will a legal one.

I agree. Thanks, Wayne.
