El Paso County (CO) Data - The RadioReference Wiki
Here are the links for the Wiki info in El Paso.
I am not sure if EPSO info is correct as I live in Colorado Springs and don't listen to much of the EPSO unless there is a major incident I hear on the Fire side then I will turn the SO on.
5280Fire - 5280Fire is another outstanding site for the Fire Departments in the state.
Speaking of the El Paso Fire, the wiki needs to edit its list:
*1600 Woodmen Valley was put taken over by the Colorado Springs Fire years ago. The building remains but there is no units in service.
*1900 series are used by Fort Carson Fire units now
*2100 series are used by the Air Force Academy Fire units
*2200 series are used by the Tri Lakes-Monument-Woodmoor Fire units
*1700 Simla Fire units from Elbert County are 2xx units. Not sure which. Refer to 5280 fire for that information. When they come into El Paso, they are NOT 1700s.
Colorado Springs Fire units go on the air by their same radio unit designation when they respond into the county on El Paso Red and the C-zones
Enjoy your listening Al.
