I was in bowling green ky saturday this what i was trying to listen to http://www.radioreference.com/apps/db/?sid=958 with my PSR-400 and PSR-500. ok on the 400 hundred while scanning it would not stop on a active freq but the 500 did. only way to listen to the 400 was to manually put it on one of the 3 freq and listen that way. i had the bank in open mode bank was set to Motorola . i programed using the win97 software . i know it will scan and pick up a Motorola Type II Smartnet as when in Goodlletsville TN http://www.radioreference.com/apps/db/?sid=983 it picks this system up good while in scan mode. anyone have any ideas what i was doing wrong? i read that manual 2 times while my wife was shoppig trying to figure it out.
