Thanks for everyone's past help on getting going with the HP-1 programming. Got the Sentinel software up and running and it reads the SIMM card. I deleted the old Favorites list and started making a new one, which I seem to be getting the hang of, of finding and entering the system I want and the individual talk groups. So far so good. I take the card in re-insert into the scanner. However, the scanner keeps reading the old favorites list that is no longer on the card. What is my next step so the scanner is reading off the card? Thanks in advance. Andy
