Reality
This is a disaster in the works, the idea is to move public safety over to 700/800. Its all part of the grant money and inter-opt-ability concept. So, where does the funding come from. You answered your own question, the issue is the money in grant funding is not enough to support 40 plus officers or firefighters in several jurisdictions. So, you space the money out and hope the county or an agency gets enough to support it. Or you go after your taxpayers threw 911 county taxes. I agree with the other person, its a joke and wont happen at least for ten years if not more. You still have way to many business and agencies that still not have narrow banded. Plus, with motorola dropping support for even more public safety radios the choices are being limited and being redone as motorola solutions read into that any way you want. You probably will being seeing a push more towards digital formats such as ndxn or idas or trbo or p25.
