Shelby Co Sheriff - Radios & MDT on line to view
I had the pleasure of riding along with a deputy.
As you look at the FCC license, Harris's VHF P25-Type II digital uses 100-watt repeaters at five or so sites in the county.
Notice the mobile radios are licensed at 4-watts.
The hand held radios do not reliably reach the repeaters. SOLUTION - They use Southern Link when away from the car. Southern Link operates like a parallel system. So if they're out of the car, they are on So-Link.

Also - the MDT computer terminals are used a lot. Calls of any significance are on the radio, not just the computer.
http://dispatchlog.shelbyal.com >> MDT Dispatches are updated every 5 minutes or so. The time is given as: 20170412214130CD breaks down as:
2017 > year / 0412 > April 12 today's date
214130 is time in 24-hr format = 21-hr, 41-min, 30-seconds, CD = Central Daylight Time
Shelby County is a highly populated county - BUT.... the more highly populated areas are incorporated cities such as Hoover, Pelham, Alabaster, etc...
They do go back up cities on calls a fair amount too.
Hope this helps!
