450-470 MHz is alive and well and still full of public safety, business and other users (including, of course GMRS and Family radios), and it won't be going away anytime soon-every new allocation made by the FCC in the future is liable to be broadband only so the channelized stuff has to have a home too-although the Public Safety folks also have 14 MHz of "new" 700 MHz spectrum which is starting to be used for channelized systems-all P25 and on 12.5 KHz channels moving to 6.25 KHz over time.

Land Mobile uses much higher power TXs which would be that much more of a problem than these flea power transmitters. Joe M.
