Trying to figure out why I would decode a talkgroup ID of 00-021? Unit ID's where Elkton PD Dispatch 807 and another 9051.
Thanks
In addition to what troymail said..
Not a mystery; your TG display settings are defaulted to AFS for EDACS.
You were hearing Patch 17 (AFS 00-021) DEC 17. If you change your setting to DEC it will be TG 17 As on the RR DB Page. Also see the wiki page for more...
