I was just wondering if anyone had an opinion on the receiving strength of the PSR-500 over the PSR-600. As the area I live in will be going digital in some areas soon, I will have to make a decision of mobile vs. handheld. My experience with the recent Uniden scanners has found a significant increase with reception by the mobiles. My handheld performs poorly with the stock antenna and/or an external antenna. I would like to get a the PSR-500 due to portability, but I don't want to sacrifice reception. I would be using an external antenna in my vehicles with the PSR-500.
