I just read yesterday that Congress is trying to pass through legislation that would push the FCC to open TV frequencies to unlicensed wireless devises (such as garage door openers, wireless phones, et cetera). They claim that these devises could utilize the "white space" between tv channels that nothing occupies. However - what many fail to realize is that this is the space that wireless microphones and IEM use. If the FCC opens these frequencies it will mean uncontrollable interference. Not a good thing for anyone using wireless mics or iems. Churches, schools, trade shows, theaters, national touring acts, restraunts, et cetera...will all be affected. The public forum has closed on this issue, but you can still write letters to your congressmen and to the FCC.
