yes, that should do it, too.
one thing I noticed though is that US receivers can be confused by 
loud audio signals. Just clap your hands, and it might take it for a 
returned US pulse. Has wrecked many performances that worked 
perfectly at home, but couldn't handle the louder stage conditions.

I don't see how this helps when the signal is burried in noise.

I would be interested over what distance you receive information from 
moving people.
And are you using the Polaroid transducers, the smaller stuff from 
RS/Farnell, or something else ?
