Is there available, can it be done to have an AM and/ and or FM

Slightly less evil would be emergency broadcasting type uses...

Apparently someone believes it's possible as an application was recently
filed with the FCC for an experimental license to operate just such a
system across the FM band. (the Commission denied the application)

Their intent was to install transmitters on emergency vehicles, so they
could warn other motorists to get out of the way.

My guess is the FCC feared these devices would "get out into the wild" -
can you imagine what an unscrupulous nightclub owner (or someone with
a political bone to pick) could do with a few of these?
