Just picked up a Uniden SDS150. Is ARC536 worth buying over the free Sentinel software?
Sentinel can be used to create and edit Favorites lists. Sentinel is also required to maintain the master database used in the scanner, as well as to enabling installation of any firmware updates.
The downside of Sentinel is that, while you can append systems from the main database to a Favorites list, appending a department form a statewide, or large regional, trunk system automatically appends
all the sites in the system. There is no way to selectively append only the single, or small group of sites, for your specific area, Whether the system has five sites, ten, or several dozen (or even more). all of the sites are added to the Favorites list you are creating.
However, if you were to become a Premium Subscriber, and use software such as ProScan or ARC536, you can select and import only sites that you want or need, along with your talkgroups of interest.
Looking at your signature line, I see that you list a 996XT.
ProScan can import the programming file from your 996XT into a Favorites list to be used on your SDS150. My preference is ProScan, but ARC536 also can be used to program your SDS150. Both ProScan and ARC536 have a 30 day free trial period, so that you can try the software before making a purchase.
