Narrative:

Departing opf after tower closed. Filed IFR flight plan. Planned route was 270 degrees and/or remaining 10 NM DME distance to avoid class B floor of 2000 ft MSL. On climb out, attempted to contact clearance delivery on the frequency published in the current airport facility directory. No response. Contacted mia departure control, who informed us that we had entered the class B airspace, which was a small angular corner to the south of our proposed route. The cause was most likely our cruise (leveloff) altitude and the frustration of not being able to raise clearance, plus rain, caused us to inadvertently enter the area that was the 2000 ft floor of the class B airspace.
