Rail - 160.215-161.565
Marine - 156.000-157.425 & possible action from 161.600-162.025
Shipboard handhelds - sometimes, marine band, but frequently 457.525-457.600 & 467.525-467.825
Some military analog at 138-144 & 148-150.8, but pretty sparse & generally low power
Lots to hear on generic low-power business freqs, and the 'test' freqs for cheap Chinese handhelds.
Lots of good vantage points to watch stuff. Waterside, Monitor-Merrimack Overlook, Fort Monroe, Port Norfolk, and the Portside Walk all are great vantage points with stuff to listen to and watch. Norfolk Int'l Airport has an observation area, Willoughby Spit boat ramp provides great view of NAS Norfolk, and Oceana NAS has its own observation lot. Much analog going on at all spots. Also a lot of interference from the Navy's ELMR in the 380-390 range--but that's a big city for you.
Have heard GMRS traffic in downtown Portsmouth that sounded quasi-military like possible a militia group.
