At 1150 UTC this morning (05/13/2013) I noticed a dasher network was active on multiple frequencies, 6551.7, 7801.7, 8056.7, 9963.7, 11276.7, and 12081.7 kHz. Not 100% confirmed yet but it looked like all freqs were in sync, pulses coincident. Pulses were about 105 msec long and occurred every 633 msec (just under 95 pulses / sec).
At this time (1305 UTC) all signals are still on the air, but the lower freqs are just about completely faded away and started fading as soon as the sun started getting close to up. ChrisSmol was unable to receive any of the pulses when I gave him a heads up. Both of these indicate a possible source west of me. This is supported by my beam bearings on the upper freqs, around 300 deg true although I never got a real good, solid, bearing line.
