said by cornelius785:i highly doubt your microphones operate in that same spectrum as these 'white space' devices would mainly based on the fact that they could never get certification from the fcc to operate in the already used TV bands. my guess it that your microphones operate in an ISM band. plus the the white space devices should be aware that some small range of frequencies is being used and should not transmit in that range.
I highly doubt you have any idea what you're talking about...
