DST -16

Propagation at < 100 miles, between KP2AE, K4FI, and W4DEX,  was good today with very little QSB.  But there was very pronounced QSB on AB4AM's signal with some S9+ peaks to the above three stations.  But K5HFG reported AB4AM 529 539 no QSB.  On CW KGØVL reported WW8II 539 up and down with rolling qsb.  WW8II was detectable but no copy at W4DEX due to QRN. 

AB4AM reported:  " K0AWU No copy at first. Short burst at 17:49:32 219 then gone"
At the same time, W4DEX heard something odd and was recording.  The recording revealed a sudden increase of noise for about one second but no signal detected.  KØAWU's signal may have been just strong enough to overcome the noise at AB4AM but not enough to for detection at W4DEX.  The lightning map showed almost constant strikes from Texas to Florida during this time.  The burst of noise was a much higher level than the continuous QRN noise level.  Sudden signal enhancements have been reported by several stations over the past few years.  Red sprites and blue jets have been observed by the International Space Station during intense thunderstorms.  So far it is pure speculation that this rare phenomenon may cause sudden atmosphere ionization that would reflect a 160 meter signal.
