I used proscan to add 5 conventional channels to the scanner. Uploaded and they work fine. All other systems seem to be working as well except for main county p25 system. it worked fine before I reprogrammed. As far as I know I did not adjust it at all. It still shows up on display by name on the scanner as being scanned and in programing. However scanner is not stopping on any of these channels of the p25 and I know they are active as I have them in an older scanner. I have tried restoring the original working programing that i had saved to a file. No difference. I tried just programing in the p25 system to see what would happen. It is not working that way either. Anybody have any ideas on what I should check .
