Yes. That's a function of the scanner, and would happen with any software.I'm thinking of buying the Win500 software to use with my PSR500 scanner. I'm not real happy with the lack of detailed support that's available for the ARC500 s/w I've been using. I stumbled on this thread and I just want to clarify what DonS wrote.
So....if my radio was pre-programmed with Philadelphia county (by ScannerMaster) and I just downloaded Montgomery county from RR.......if I just tried to upload Montgomery county to the scanner....it would wipe out the Philadelphia county info that's in the scanner?? Scary!
If you're making changes on the scanner, then you'd have to do that. However, if your only changes are within the software on the PC, then you can just save a file on the PC. When you later make changes, you'd load that file (which reflects the scanner's current contents), make your changes, save the file, and upload to the scanner.So then, each time I download something from RR I need to dump the radio into Win500 first, then "add" the new county to the software and THEN upload all to the scanner. Is that correct?
