Not overly familiar with that scanner personally as I use the PRO668. When I go into my trunking category in the program on my PC it gives me numerous options such as adding a frequency to a trunk, renaming a trunk, renaming a TG ID etc. One of the options it also gives me is to add a "wildcard" talkgroup to a particular system that basically picks up every TG on the system. I can then "see" the ID and monitor the conversation with a further option to store the newfound ID.
Being that your scanner is better than mine in a number of areas I wonder if you might have that same option somewhere?
