We are ready to migrate to Digital. The CP200 UHF is what we have now. What are my options. Would prefer a smaller, but durable version. Anybody have some experience with the newer radio's. I would think 4 to 5 watts is needed but that's a guess. Does digital go through buildings better.
Digital does not go through buildings better than analogue. What does influence building propagation is the band used, not the modulation being employed.
That said, the XPR3500 would be a good replacement if you insist on paying more than you need to for a radio. If you want a radio that is functionally like the CP200, just as durable, but cost less, look at the Vertex Standard VX-261. The company I work for, have somewhere between 70-100 VX-231 deployed and they have been rock solid.
While the VX-231 are obsolete, they have been replaced by the VX-261, and I would expect them to be as durable as the VX-231.
Not sure on price but I would guess they are significantly less than the XPR-3500.
