143.7000 MHz: Internal radio net of a Fairfax hospital, I think. Every once in a while you'll hear a radioteletype.
152.1750-152.6250 MHz: Radioteletype
153.0550 MHz: Interesting conversations. Short, sweet, and to the point.
154.1550 MHz: Fragments of conversations. Buzzer. Occasional musical notes (more complex than simple tones). Not much traffic during the normal workday.
