If you have the sentinal software loaded, create a new favorites list, put in a name for the favorites list, like "Benton Co test". Then highlight that, and you should see Systems tab highlighted on the right. Click the + and create a system called AWIN. Click on the new AWIN on the left, and on the right, click the SITES tab. Create a site with the + button and call it Rogers. Then on the left, highlight Rogers, and on the right click the Frequencies tab. Enter the frequencies I posted above. Then go to your Profile and select Monitor On, download ON. That should give you a blank Awin site, with no departments. If you select ID Search, it should stop on every talk group ID that transmits on any of those Rogers Awin site frequencies. Then just listen for the agency you are trying to get. If you hear them, then they are on the new system. Write down the talk group IDs you hear them on, and post them so Milf can get confirmation and put it in the database.
Another method, which is a LOT slower in scanning, would be to just go to Sentinal, click the + next to USA, the + next to Arkansas, The + next to Benton, the + next to Statewide. Then highlight the Arkansas Wireless Information Network (AWIN) line (4th down) and right click. Select Append to Favorites list. In the pop up box, cleck NEW FAVORITES LIST, and then load that list into your scanner.
