(meteorobs) Large scatter event 21 March over OK/TX - anyone see anything?

[James Beauchamp]

My Space Radar Scatter receiver recorded what could be a very large event 21 March over the Kickapoo transmitter.  I've seen no events like it in the last 60 days of solid observing/recording.  
 
It shows what looks like doppler from the object itself, followed by large debris/trail scatter spectrum.  Single objects like the ISS or large satellites show the line.  Large bolides disentegrating in the main beam of the fence usually present the debris/scatter pattern only.  I've yet to see two correlate like this.
 
Of course, it could have been pure coincidence (maybe ISS at the same time), but unlikely.
 
See the linked capture.  The main radar frequency is centered at approx 850 Hz (tropo scatter is visible).  The two smaller trails are airplanes somewhere.  The light line at 1100 Hz is unknown, but comes and goes.
 
Time was approx 14:07:20 UTC, 09:07 AM Central time.
 
Anyone else in the South Oklahoma, North Texas, West NM, or East Arkansas see anything that may correlate?
