ADS-B feeder Performance Degradation

Starting on or about November 30th I am noticing a serious performance degradation in one of my ADS-B receivers. My setup is a south facing receiver, 18 miles from KORD, and a north facing receiver. South always outperformed north until the timeframe above. It went from 260,000 positions to 115,000 in just two days. I have checked those obvious things but have been unable to resolve. The north facing receivers showed no such decline. I would welcome any advice on what else I could/should check. Running PiAware 4.0 on both receivers
