Laurie & all Looks like the signal was building pretty well at my location when it abruptly died. Capture attached. http://www.advancedreceiver.com/capture/G3AQC120602.jpg I'm surprised John A. let any signal by his antenna to make it to my location. He must have had more signal than his loop/preamp could deal with and some spilled out! Jay Rusgrove, W1VD
