US DHS sent forms to every State, and Federal agency with the official nomclemature for ALL the interoperability chans, UHF, VHF, 700 and 800. The communications people at State levels should notify all first responder agencies of the changes. The whole idea of reaching interoperability is to get everyone on the same page in the same book. It would be nice if everyone would do so, but that seems to be the main problem now... Everyone has the right freqs, but won't use one language to name it. Offical freqs, tones and names are there... just have to be utilized correctly.:twisted:
