XDW (square wave) hung in there until about 0800Z then disappeared until the sunrise enhancement period. Listened for EMP, however I have a couple carriers 5 Hz south of his frequency. A QRSS 30 or 60 run from EMP would be nice ... Sunrise at http://www.w1vd.com/grabber.html . Jay W1VD WD2XNS WE2XGR/2
