I described the protocol in my earlier message.  The number of channels is
variable but typically eight.  Bandwidth would be a few kilohertz
depending on how much resolution you want and how much signal/noise you
think you can play with.  It is not a particularly bandwidth-efficient
encoding.  I'm sure that the bandwidth in practice is limited by
regulatory concerns - if you want a much higher sampling rate and you want
to do it *legally*, then you're going to either be limited to flea power,
or forced up into the UHF.
