What else are you looking for ? The base basically consists of the piers where the ships dock, the office buildings, the Navy Exchange, and housing. I can't think of anyone else who would use a radios other than the police and fire. I believe the fire department and local surrounding towns handle the ems calls. The ships have radios but they probably don't use them unless they're at sea. There is a DPW frequency floating around on one of these sites but I can't seem to find it.
