Yeah, it's a bummer - I have a 785 (no digital card tho) and a 780 but still use them for all the non-trunking stuff. I sold my Pro-2006 to get the 780. Ha!
It's been a few years since I messed with the 785 and trunking. I use ScanCat software and used to be able to pickup Roseville and Sacramento stations. I will get the software running again and do some searches and see what I can still receive. I haven't kept up with the changes with trunking so I need to do some reading and try to get caught up. If nothing else I can use the scanners for amateur radio and aviation bands.
I also have a 785D with the digital card. I'm going to take the card out of it and put in the BC296D I bought on Craigslist that didn't come with a card. The 296 is rebandable.
