Okay, I have read enough threads like this about "Get Uniden for cities and GRE for other areas"
Well I own a Pro-106 and a 396XT and carry them with me wherever I go and this is what I experience.
I live in a metro/suburban area so there is plenty of interference. When monitoring my county's digital trunk system my Pro-106 does better most of the time. All this interference that is talked about doesn't seem to affect my scanner's reception of this digital trunk system (and if it did then it is affecting both equally)
The other day I was parked almost directly under a cell tower. My pro-106 was chattering away as usual while my 396XT was silent, I looked at the display and the 396XT couldn't even find the control channel.
Now, with that said, I will agree that if you were monitoring an analog system or some analog conventional channel the 396XT would be a better choice, especially near cell towers, as you don't hear static along with transmission like you would on the 106.
Guess my point is when it comes to digital, doesn't make as big of a difference as some seem to make it out. In fact while typing this at home, my 396XT can't find the control channel and my 106 is working like normal.
Don't get me wrong, I love both scanners still.
