I knew it had nothing to do with receivers of any kind. My misconception was since it was such a powerhouse that its signal strength was really large and there for in a simple receiver it would, depending on QTH, simply swamp out other signals. Thanks again! This is new to me over here.

Is this the "Luxemburg effect?" The Luxembourg effect has nothing to do with crystal sets! The Luxembourg effect is when a very high power transmitter causes non-linearity in the ionosphere resulting in mixing of different rado signals. This effect was 1st observed prior to WWII on the very high power LF transmissions from Radio Luxembourg. 73 Warren K2ORS
