Several talkgroup ids have shown up on my scanner. I am able to find most, but have a few that do not correspond to anything in the talkgroup ID list for the New Jersey State Police. I am curious if there is something happening that I don't know about. Could these be transmissions that are overunning other frequencies? Anyway, the ids are as follows: 52144, 61472, 30928, and 26912. I have definitely heard transmissions on these ids. My scanner is programmed correctly. I would greatly appreciate any help on this matter.
