I am looking for a scanner for mobile use while in a vehicle. I am looking at the TX-2 since it has a detachable faceplate. I currently have a GRE PSR-800 that was recently upgraded by Whistler. My question is regarding performance. The GRE seems to do well with a P25 non-simulcast system in Missouri. Would there be any reason to not expect a TX-2 to do as well?
