True, there are patches, but being that the City system is VSELP,.. only a user of the system will be able to hear it. Whereas any patches on the County system would be monitorable unless AEGIS encryption is turned on. Here's to the day that the proposed Motorla Smartzone combined City/County system comes into being... assuming the grants all fall into place, the powers that be all agree to work together, and any other number of things that can go wrong, don't. Then scanner users in Memphis will be happy happy happy. And when the TN DPS system eventually grows out, it'll make things very interesting indeed. Concievably one could, in the future take a say PRO-96, and listen with no issues from the ArkLaTex, clear to the Atlantic. At least on the most traveled routes. **Not including FL of course**
