We're totally receptive to such details. Please share. Thanks!
Without knowing even the basic info, that's a little hard. Can you tell us, at the very least, what band you operate in?
I'd start with ebay, you can probably find something in the Motorola HT750/1250/1550 (Waris) series or the Icom F series that would meet your needs. What radios are you now using? You obviously have the Motorola RSS/CSS for something, so you could look for that series of portable to see if there are any deals available. It would give you the ability to program with something you already have. Without any info though, we can't offer specific, legal solutions.
As suggested above, SAFER grants and UASI grants are worth looking at. The UV-5R is not type accepted because it doesn't work on the designated frequency, it isn't type accepted because of the amount of harmful interference it can cause on other frequencies when operated on the designated frequency. Put yourself into the other users position. If a local business or another public safety agency had UV-5Rs in operation, and every time they talked, your frequency became unusable, how would you react? It is potentially life threatening and the radio operator doesn't have a clue they're doing it. In a public safety application, it can put lives at risk, which is the exact opposite of the intention.
