Yes. The 30 day demo is fully functional.
Basic steps:
1) Open or create a new database.
2) Click on Import - RR.
3) Enter your login info.
4) Choose the Country, State, County, etc...
5) Click on Retrieve Data.
6) Select the Site and Groups you want.
The 780 is limited in memory so you can only import 100 TGID's at a time and 50 frequencies at a time. For more TGID's, import again, choosing a different bank.
Does ProScan work to pull info off the RR database in demo mode?
I couldnt get it to work with my BC780 about a week ago.
