I am trying to decide what type of radio to use to feed Unitrunker to monitor Moto SmartZone. I have 3 choices: 1. an SDR device, 2. one of the suggested scanners that support CC streaming output (like PSR-800), or 3. a regular scanner with discrimintator tap. I don't know the pros and cons for each. I have a few unused scanners that are tapped already, so that is easy. I have a USB SDR that gave me fits with drivers and virtual audio cables (it is now safely kept in a zip lock bag where it can't hurt anyone). I don't have one of the CC streaming RS/GRE scanners, but I could get one if there are advantages of using it over the other options.
