Hi all, I've had a PRO-433 for years and I love it. Long story short, the one thing I really hate is that there are no alpha tags for it. I use it infrequently so remembering what freq. is what is a pain, esp. with trunking. The PRO-163 has tags and is very similar with one big difference- it's made by GRE. I have a GRE PSR-300 as well, it's not bad, but I've decided that I like the Uniden made models a little better. The reception on the 300 doesn't seem that great. Anyone own both a PSR-300 and a PRO-163? Since the 163 is a base I would think it would have better reception than the handheld PSR-300. Any input from 163 owners would be appreciated. Thanks!
