Narrative:

After takeoff given clearance to fly a heading of 210 degrees for radar vector to pgy. I read back clearance and selected 210 degrees for first officer to fly. We passed 210 degree heading to about 190 degrees. I called out heading 210 degrees, rolled to about heading 180 degrees before immediate right turn back to 210 degrees. Confirmed heading with departure control, no questions asked. First officer thought we were given clearance to fly direct to pgy. Radio side tone weak. I should have made sure he understood clearance when I selected the heading.
