All,
You basically have a choice. RR is an excellent source for talkgroups and frequencies and it's free for their basic service. My publication does cost money but it has much more detailed information that's not in other sites. People are angry because I charge $$ but there is alot of work that's involved with updating the book and verifying the information. Remember that RR also charges for a premium service.
As for copyrights, look at any printed scanner publication with frequencies and talkgroups (like the Scanner Master printed books). They all are copyrighted. Even Police Call was, which used information directly from the FCC database files. Even RR is copyrighted. At the bottom of the web page is - Copyright 2008 by RadioReference.com LLC
I also have nobody in my pockets, the positive reviews of my book are from very satisfied customers. But I did see that you were only joking GCR
GCR, also I see that you mentioned that an FOIA request to an agency would produce talkgroups since they are in the public domain. How can one get around the various exemptions that an agency may use to block such "confidential" information from being released?
Getting back to the main topic above, Burlington county. There are over 550 talkgroups for Burlington County. I have most listed in the Philly Guide. In fact I am in Florida now but when I return in a few weeks I will be updating the talkgroups for the latest changes/additions that have taken place over the past few months. But I believe that the original poster wanted to know if there are any free sites with the talkgroups. Unfortunately I know of none.
