Narrative:
Potomac approach took us off airway and cleared us direct staut NDB at shd airport for the visual approach. Approaching staut, we called the field in sight and ATC cleared us for the visual approach. We started out of 6000 ft, canceled IFR, and switched to unicom. Our TCASII immediately alarmed 'traffic, traffic.' we looked at TCASII, and traffic was 9 O'clock position and less than 1 mi, climbing rapidly. The TCASII then immediately alarmed with an RA commanding us to descend. We took evasive action and saw traffic pass off our nose at a rapid ascent. ATC had not told us of any traffic nor had anyone reported position on unicom. TCASII reported clear of conflict and flight continued normally and we landed.
