Most likely that one of the coils in the pitch antenna circuit has gone open circuit. If not this, then an open circuit to one of these coils on the printed circuit board. This happened to my EWPro once several years ago, Rudi fixed it in (under warranty)about 10 seconds (I live in Germany), but only by sacrificing a coil from a "spare" EWPro that he had in the workshop.
Good luck...
