Donny,
That MAY not be a wireless problem. I work lots af areas where large attenae transmit radio signals right through my speakers. Roxboro Pa is just such an area, and I hear Jerry Blavat yappin in my ear all night long!

MI have several wireless mics, and if you have a uhf, true diversity mic with a good element .... it is every bit as good as a wired mic. The only trade off is a slight frequency dip on the high end, but that is usually corrected with EQ, and mostly undetectable.

Wireless is here to stay. I'm sure midi will be wireless soon too. The technology exists now, but it's not practical or economical yet.
