LOS ANGELES – It will cost $51 million to purchase new radios for Los Angeles Police Department officers, according to the Web site www.nbc4.com/. The department has used the Astro radios by Motorola since 1994, but often run into dead zones while on patrol. Because the city now faces a $245 million budget deficit, the funding will be hard to come by. It would cost $43 million to purchase 10,000 new hand-held digital radios, and another $8 million for 350 mobile radios installed in police cruisers, NBC reported. The Police Commission’s executive director will soon draft a letter requesting that funds for a new radio system be included in the city’s budget.
