The Pro-18 is a great little radio. Mine gets along just fine with the Safe-T system. The garbling I hear usually is associated with weak signals; you can check the signal strength meter when you hear something that sounds "underwater." A better antenna will improve this or just delete what you don't want to hear that is too distant. I'm relatively new to trunking and digital and at first I got tons of stuff I didn't have the least bit of interest in hearing on Safe-T, a lot of it distant, weak, and garbled; now that I've somewhat figured it out and connected a better antenna, I hear what I want to hear, very clearly. Best $200 I've spent in a long time.
