Locating Stl FD/EMS talkgroups

[kc9neq]

I use a 396t and 396xt to monitor St. Louis PD/FD/EMS p25 radio traffic. I have the towers and talkgroups programmed via radio reference. I downloaded a scanner app for the I phone.
I found that while using the iphone app I get more EMS traffic. This EMS traffic sounds p25.
Any suggestions as to how I can find these talkgroups to be used in the 396t and 396xt?

Also any suggestions as to how to use the close call feature to find the talkgroups?

I also have a 396XT, I have the ID Search as while as the Unit ID on too. It seems the job for me.

I am interested as to how I can find the STL EMS/FD talkgroups that are not listed in the radio reference data base.

The St Louis Fire Department has talk groups in the database.

And last I verified it's up to date. If you're worried about missing any unknown TGs then like was said set your scanner to ID search. If you think you're missing EMS transmissions verify the TG and your scanner settings.
