Well I rushed right out to Radio Shack. They had a $20 lapel mike that broadcasts to a standard FM radio. They also had $70 lapel mike that broadcast to a special $80 receiver unit. It used frequency's higher than regular FM and had a potential of 8 separate channels (using one at a time). As usual at Radio Shack, the guy knew no more than what the catalog said.

I am interested in this solution, but I need to know how to input into a PA system with the cheapo mike. It seems this technique is working for a few 'Catters.
