phase 2 p25, the Motorola type 2 system will mostly be quiet now, they've moved on to a Harris phase 2 system. a p2 scanner either 325p2, which will be easy to program if u have your 396xt backed up to butel ARC-xt.. u can transfer your info in the scanner to the 325p2. thats the easiest way. if u want to go a little more expensive, and especially if u are near simulcast sites u will need either a sds100 or sds200. although all phase 2 scanners will work. the sds scanners work best for simulcast sites , less distortion.... its also 700 mhz
