talk group id's and frequencies

Is there a program that will catch or read talk group id's and 
frequencies? What IM trying to do is find the talk group id's and 
all the frequencies for a business so I can scan the radio traffic. 
Thank you, 
Matt

If you have come here to find out about the 785D you have come to the right place! In fact the discussion of the BC-785D and how it works is the only acceptable topic on this list. Any discussion about anything other than the BC-785D is OFF TOPIC. I hope this is clear to all group members..
