Narrative:

Pilot was ferrying a single engine light aircraft VFR. While attempting to obtain radio contact and subsequent radar vector to small airport outside atl class B, pilot realized he had radio malfunction. Pilot attempted to rectify radio problem and believes he may have inadvertently entered the bottom northeast edge of the atl class B. Upon recognition of his position via landmarks pilot immediately executed a turn out of possible class B airspace and concurrently commenced a descent to ensure being below the class B edge/bottom. Pilot believes that had he not tried to correct the equipment malfunction and simply navigated first, the situation would not have occurred. Certainly a backup communication system in the aircraft is another way to avoid this kind of situation.
