There are other posts in the Virginia forum indicating that Brunswick County is going to a new UHF radio system, which may be digital. The current database page mostly shows VHF frequencies, which I assume are older. I don't know the status of the UHF system - whether it is still being constructed, is in the testing phase, or if they are now using it for real and the database page hasn't been updated. But this thread lists at least some of the UHF frequencies they are planning to use: https://forums.radioreference.com/threads/brunswick-county-new-uhf-frequencies.360429/
I suggest you try the frequencies given on the database page provided by NYRHKY94first and see if there is any activity. If there is, monitor the Virginia forum from time to time and see if anybody indicates that the new UHF system is becoming active so you can get prepared for it.
