Scanner stuff isn't my sole hobby, so I never took trying to improve reception of simulcasts in my area (Phoenix Arizona, many sim systems) with my ancient 996P2 seriously. Not until yesterday when I finally said OK I may as well get the SDS200 as I've been reading about it for years, but other hobbies took up my time, and money! and I didn't think the SDS200 a good investment. I was wrong. I can't tell you how pleased I am with this scanner. I am receiving "stuff" I never received on the 996! Simulcast, schmimulcast! I love the very simple Zip Code/location selection - whatever it's called, I am just thrilled with this and kicking myself for not getting one sooner. The 996P2 seems so feeble and obsolete now. This made scanning fun again! This is the kind of stuff I dreamt I would be hearing, years ago when I got my first Trunking scanner. Favorites/Profile is being created now, but I am getting a kick out of monitoring the "builtin" database, I have it set to my local zip code with range as "10 Miles". Just fabulous. I am just now creating Profile and Favorites, and figuring out the Sentinel software. I may go wiht Proscan if I find Sentinel not great.
