There were a number of issues with the BC25i card coming unseated or not being recognized by the scanner. I *think* (it's been a number of years) there was a firmware fix issued for this problem. That's assuming that these talkgroups were programmed as being digital, of course.
Are there any mode 'E' talkgroups from the database that got programmed? These are encrypted and you will not be able to listen to these.
Just a few random possibilities...
