Gareth,
My state transitioned to a state-wide 700/800 MHz Motorola P25 system about 2 years ago, to replace their VHF High band / VHF Low Band system. So far, there have been a number of both complaints and accolades about the system - and it appears that what you hear depends upon whom you talk to. Many users "on the street" complain about "motorboating" voice quality, background that covers the actual message being conveyed, "dead" spots / inability to access the system when needed, etc. Other users gloat about the ability to be able to "talk across the state" from one mobile unit to another. My personal, unscientific analysis: when it works, it works well. When it fails, it fails VERY badly. It really depends upon the application - for business, it is most likely a very good protocol. For public safety, I have my reservations. If you want details, contact me off-list and I'll try to be of assistance. ;-) Good luck, and be sure to do your homework. you'll need it!

The town I live in rolled back from a 800mhz apco p25 back to their analog VHF system.

The repeater issues (If any) are especially interesting for me, and would be very interested in hearing feedback from my colleagues from around the globe.
