Quite possibly, depending on what Richmond uses. I was in NC and using VIPER. All the VAMCS, HCCs, and CBOCs in NC use VIPER for their police comms. Each HCC and CBOC uses their parent VAMC talkgroups with the ability to use the other VAMC talkgroups and their local jurisdiction police groups (if they have gone to their AHJ or County Emergency Manager and requested it). That's how it works in NC at least.
Of course, Richmond might be different based on the distance as you stated.
I enjoyed the VA employment years. Makes you feel good helping others. The rest of my 34 year career was with Navy as a federal employee.
