Sayonara analog, hello digital. The town\u2019s public safety radio system will be transmitting digitally this month thanks to the completion of a multi-year overhaul that featured six construction sites around town \u2014 and out of it \u2014 that link communications for the police, fire, fire police, highway, emergency management, and parks and recreation departments. The last piece of the puzzle \u2014 Moses Mountain tower, across the Danbury border \u2014 was finished in early June. Now, incompatible radios at the scene of an emergency \u2014 including garbled transmissions and weak signals in many areas of town \u2014 are a thing of the past. \u201cParks and Recreation and Highway are involved because during a major storm they\u2019re clearing roads, plowing, taking care of wires,\u201d said Acting Emergency Manager Dick Aarons who has been overseeing the $3.7-million radio system upgrade for the last half decade. Moses tower Aarons said that the Moses Mountain tower took the longest because of unexpected complications. \u201cIt took us a whole year \u2014 or a little bit longer \u2014 to get permission to work on that tower,\u201d he said. \u201cOnce we got that permission, we finished our work in three weeks.\u201d But, even before Moses Tower was complete, Aarons said that a large part of the system had been up and running for months. \u201cParks and recreation, the highway department, the office of emergency management and the fire police \u2014 they\u2019re already using the new radios on the new digital system,\u201d he said. The holdouts The two departments still communicating on the old-school analog system? Fire and police. Aarons said that the new radios have been installed, but those departments have yet to make the switch to digital. The plan is for both the cops and firefighters to be on the new system Tuesday, July 25. Aarons said that, with the digital signal, emergency responders will be able to communicate from their portable radios from any home in Ridgefield. Testing The new system seems to be working even better than expected. \u201cSpecially equipped police cars, driven by police officers, took engineers to all areas of the town and several areas in surrounding communities to check the performance,\u201d said Aarons. He said that the radios installed at headquarters and emergency vehicles have an easier time picking up the signal because of their large size, but that the extraordinary aspect of the project lies in the smaller radios. \u201cWhat we really care about are the radios that officers and fire carry on their belts,\u201d he said. \u201cWe have to be able to make those communications so that the people on either end hear the transmission loud and clear.\u201d Testing yielded positive results. \u201cThe most exciting thing is we\u2019re hearing back from the officers that they\u2019re able to communicate now,\u201d said Aarons. \u201cIn every case, the performance met or exceeded our original expectations."
