Narrative:
This report is on equipment. Bwi airport primary radar has been out of service for over a month. We are working secondary radar only (transponder equipped aircraft). On the dates above, balance VORTAC has been taken off the air. WX has been marginal VFR. This creates a condition where it is almost impossible to provide non radar service to any IFR aircraft without a transponder or to any aircraft that loses his transponder while en route.
