Using "Dupe" on PSR-600
I can use an assist if someone has the time. I'm trying to "Dupe" a P-25 digital system. The system I'm working with has two sites, north and south. They share talkgroups across both systems. I have one system completely programmed in the radio. I have been using manual, finding my original TSYS in scanlist 1, pressing "Dupe", which brings up a copy of my original TSYS. I go into program mode and change the parameters I want to change for my "new" system and after saving the new control channels and scan list number I discover that the new scan list number doesn't save, but instead it reverts to the original scan list number. This in effect overwrites the info in my original TSYS. So in summary, it seems that I can never have an original and a modified copy. What am I doing wrong?
