New digital modulation type, labelled as "APCO Project-25" P-25 pretty much is the same modulation that cell phones use. P-25 is supposed to give better voice quality, but there really is no differance. Plus I need to buy a new radio scanner now.
There are two types of P-25, 3,600 baud and 7,200 baud speeds.
