My Orion2 finally met it's match. HB9RDE was on 18.112.5 running 50 over and I was trying to copy EL5PM running S8 on 18.115.0, a new one for me. The SteppIR beam was headed 100 degrees from the Western New York area. It was all the O2 could handle! Still, it's a great receiver. Got him later when the HB was not on. George
