ERV (Emergency Reatoration Vehicles
As a uniformed Prorective Services Officer for Pratt & Whitney Aircraft, I was fortunate to get the Nicole tour of one of the ERV's at Rentschler Field. The door was open and they caught me with my butt hanging out while I took a peek inside. The tech who was inside asked me if I would like the tour and of course I said yes! I don't remember all of what he told me but the general jist of it was the vehicle's primary purpose is to replace a trunked site during times of malfunction and scheduled down times that arise. It made sense as a "go pack" (a complation of necessary gear pre-packaged that could be transported on a moments notice.) but the secondary purpose of utilizing the vehicles at special events has done more to justify the vehicles for the reasons stated in the previous reply to your questions. He told me the idea of these ERV's are nothing new, that they were in use by others before CSP's trunked system came along. So the concept had been well thought out. And CSP included them in the initial requests for proposals. The vehicles also can patch just about any comms system together, including cell phones. It can cross patch... from one band to another, using different modes of transmissions (conventional to trunked both analogue and digital), etc. By the time the tech was finished, he had me believing if need be, the vehicle could bounce signals off the moon if necessary! Of course, I wanted an ERV to take home with me! I had thought the added expense of these vehicles was a frivolous expense until that day. I thought in the case of a site needing repair it only needed a repairman's visit, not an entire self contained site replacement. How very wrong I was to think that. The vehicles have paid for themselves many times over.
