It looks like the FCC will be auctioning off the bandwidth above 600mhz after 2016. Sennheiser has posted more information and a petition to provide compensation from the wireless and broadband companies that will end up with the spectrum for the replacement of radio mics in those affected blocks. Let's protect what bandwidth we still have. If you don't already have it, GET YOUR FCC LP LICENSE EVERYONE!!!!
