[sudo-discuss] Copwatch Radio Scanner

Hey folks, Berkeley Copwatch is in need of a new police radio scanner! It seems that the police department has switched frequencies/gone digital and their old scanner doesn't work anymore. Does anyone know anything about police radio/scanners and would want to have a conversation with me about them? Anyone know anything about some of the sdr options available and whether or not we could realistically hack something that would be effective? Any help is great! Max
