I've had my 125AT for about a year now. It can get what shows as AM, NFM and FM listed here Radio Reference. You won't hear anything listed as NXDN or DMR or P25 (it can pick them up, but you'll only hear screeching as the 125AT can't decode them=digital channels). Scanning the banks is fine, you'll want to input things from the database here. I use the Uniden Software, it's a bit clunky but works fine. You plug in the USB cable from the scanner into your computer. The Uniden software looks like a spreadsheet, you can copy and paste the names and frequencies from the various listings here into the banks. You got an upgraded antenna, you should be all set. I keep my scanner on a window ledge by my desk, it doesn't get much indoors away from a window. Should be good to go.
