CSP shows up on numerous Control Channels throughout Colorado.
Copy all of the CSP listings from the Colorado DTRS listing on the Radio Reference website to your scanner and then select which tower site you want to monitor.
From Loveland you should be monitoring at least the Horsetooth conrtol channel as it provides the best wide area coverage for the Loveland and Fort Collins area.
It is currently on 868.88750 but will probably move to 853.88750 in the next few weeks.
You should not have to enter any of the other frequencies listed on the Horsetooth site for monitoring the P25 system since the CC directs the scanner to switch to any other frequency as needed for listening to the CSP or other talk groups that you have saved in your scanner.
I am in Fort Collins and use a PRO-2096 connected to an outdoor antenna. It is a small 4 element yagi pointed south so I can pick up most of the Denver Metro towers as well as the more local ones. I use the Lookout Mountain tower to monitor most of the metro stuff.
