Narrative:

Departing mrb for hpn on instrument flight plan. Was given a clearance void time of AB04. Started takeoff roll right at AB04 and contacted dulles approach about 1 min thereafter. Dulles acknowledged my call, but nothing else. After a few mins, I called again and asked 'do you have me?' dulles answered that my clearance void time was XA04, then said 'radar contact.' I suspect dulles departure forgot my initial contact immediately after departing mrb.
