I missed your last trip...but if you come up again, here's some help regarding frequencies. I do not have a PRO106, so I can't help you there.

Police: 160.215, 151.4 (makes extensive use of NYCOMCO's EDACS system for secondary radio traffic, so you'll need to load in both the USMA trunked system and NYCOM's Beacon tower to catch all area radio traffic).
