YOu're not feeding full range stereo with desire for high
fidelity with these things I"d assume, so communications
grade audio should be good enough. GO for the wireless mic
frequencies with a license or regular commercial UHF
business band, get the license, have the higher power and
the advantages that come with it.

I was presuming full range stereo. If you just need communications grade
stuff, there are LOTS of alternatives out there, some of which are just
solid as hell. I'd first start looking at low band VHF gear... there is
a lot of it out there, and aside from the itinerant frequencies (and the
broadcast aux frequencies), the licensed channels are dirt cheap.

wIth these low power fm broadcast band transmitters you have
to watch your field strength to remain within part 15
limits, but yet you want some height and possibly a gain
antenna which would possibly put you over legal limits.
terrain and even objects between transmitter and receiver
can degrade the received signal and the way to combat that
is better antenna systems and a little more wattage out the
back end.

I don't think I'd want to rely on something like that for an application
that had to be reliable. Things like paging systems at outdoor events
have to be reliable, if only because they sometimes have to be used for
crowd manageent in crisis situations.
