Thanks for the info and I am using a RS pro197. I didn’t see any sites dedicated to CSP traffic near me.
Apologies if my previous reply was misleading. I meant it more as you should select sites that are designed to cover a particular geographic area that the agency is normally found in.
Colorado DTRS, like most large multi-site trunked radio systems, uses the process of
affiliation to determine what radio traffic a site will carry. A radio basically checks in with a site with what talkgroup they are using so the site will know what talkgroups to transmit over the air. This works to preserve frequency resources as it is not possible for any single site to carry all traffic on the system at once.
As a scanner user who does not have an actual radio, you will want to select sites that will most likely have an affiliation for the talkgroup you want to monitor. A general rule to follow is to select sites that are close to what you are trying to monitor. The database has a
site map that can be used to see site locations. Keep in mind that Colorado has a lot of geographic features, like mountains, so the closest site might not be the best one. There are also a number of special exceptions for certain sites which makes picking the right site a bit complicated.
A few users program individual sites as their own systems to monitor certain talkgroups because of this. Lookout Mountain (1-008) provides good coverage for a big part of Jefferson County (and other parts), so it is the first site you should try.
