Ft. Smith does not use the 453 mHz stuff anymore, they are totally AWIN. They have even moved the street, bus and sanitation departments over now. I am not certain but I believe they have even removed the non-AWIN radios from the cars.
I have not heard any traffic on the Sebastian Co EDACS system for over 11 months now. I have it in my Pro-97 and used to hear them all the time. When they and Ft Smith went digital with AWIN, that spurred me to buy my Pro-197.
With AWIN, you need to take a look at the Arkansas AWIN maps on the wiki and pick towers you could probably hear, Ft. Smith Simucast and Hartford will probably be your best bets. Next pick your talkgroups. Sebastian Co and Ft Smith would be the first logical choices. If the Pro-2096 can mix digital with analog, one of the fire pager freqs on the 155mHz band for Sebastian Co would be in order. They tone out all the rural fire and Greenwood fire departments on that set of repeaters. Pick the fire repeater closest to you. No need to load all of them, they all simulcast together. There is also occasionally voice traffic over them.
You need to be sure you know how to create systems and talkgroups in Win96. You also need to know how to assign a talkgroup to a specific system. I am illiterate when it comes to Win96, I've never even seen a screen capture of it at work. You can probably get help with that in the programming software forum if you need it.
I have a Pro-197 and use Win500 to program it. What I did was go to the AWIN page, got it in PDF format and printed out the entire list. If you are not a premium subscriber, I can get a current list in PDF format and email it to you if it would help. Print it out and then go through the list to find which talkgroups you want to monitor. I always found that easier to do in a recliner with a highlighter than on a computer screen. With Win96, at least it will be easier to type them into the program and load them into the scanner than it would have been to have to manually enter them directly. Been there, done that, didn't even want the t-shirt.
Scanning with a digital scanner is a different world. Not like the old analog days where you could just punch in a set of numbers and take off. However, it is rather satisfying to sit back after all the work and listen to the results.
I am 20 miles east of Ft Smith and will be glad to offer tips or frequencies if you need them.
Good Luck!
