I see that there are no quick keys in your file, so everything scans all of the time and you have no control over what you want to monitor. Personally, I would create separate systems for each county so you can select counties with the system quick keys. Hamilton, Butler, and Clermont Counties have a huge number of talkgroups on MARCS. If I remember correctly, the Hamilton Co/Cincinnati file I did has 500 talkgroups which is the maximum allowed per system. I had to delete some of the DPW talkgroups to avoid going over the limit. You may want to assign both the Hamilton Co and Cincinnati sites to the same system quick key since both sites are used in the system. You will be able to toggle the Hamilton County system on and off using a single quick key. As set up now, you can turn each site on and off individually to determine which talkgroups affiliate with each site. Please let me know if the quick key instructions helped answer your questions about using quick keys and if you have any other questions about programming..
