I have been scanning with my Uniden Bearcat BCD996XT under Butel ARC XT PRO Software. Today I searched 162-174 mHz with digital only selected and NAC search on. Most of the logged hits make sense, but several have me puzzled. Two of them showed a NAC code "NONE" and two other ones showed "0" in the NAC column. As I understand it, if I am hearing valid APCO P-25 modulation it should log a legitimate NAC code, but the two displaying NONE and the two displaying 0 have me puzzled. Does anybody have any thoughts on this?
Also, on a somewhat related note, how does the BCD996XT behave if I select analog modulation only and a P25 signal is received? Does it simply mute the audio or does it scan past it?
