The Newtown Board of Selectmen has proposed upgrades to the town's emergency radio system.  $7.5 million would improve the dispatching and communications equipment, with a goal of reducing dead zones.  The two year plan would replace major components that are end of their useable life, because they were upgraded in 2001.  New transmission stations would be constructed and analogue equipment would be replaced with digital.  The capital improvement plan must be approved by the Board of Finance and the Legislative Council.  This comes as the town gets set to open a new police station next year.
