Sorry if this is a dumb question but doesn't a Phase 1 capable scanner means it's also simulcast capable? My 2096 worked just fine on the GATRRS system in Austin when it used to be Phase 1.
No. Unfortunately, many of us were sold scanners by Uniden and Whistler with no indication that they would not work well with simulcast systems. Yeah, I'm still a little bitter about that.

Really, your only options are the Uniden SDS 100, SDS 200, and Unication G4 or G5. Otherwise, you can try to use yagi antennas and holding your mouth just right, and you might be able to get some reception. However, that doesn't work when you're moving around. Simulcast issues have and continue to be discussed elsewhere on this site and elsewhere. I would try moving the scanner around within your home/business and see if there's a sweet spot, before investing a lot of time and money. You might also take it somewhere else and try it, just to make sure it is working in some locations.
