[Lowfer] EAR in KS

[JD]

As I suspected yesterday evening, the noise levels varied considerably
during the all-night attempt on EAR. The storms moving east through the
Midwest began abating around midnight, Kansas time. The QRN decrease does
not account for all the improvement seen during the attached captures; it
amounted to only half an S-unit, whereas the improvement in visibility is
closer to 8 dB, according to Argo.  But, since both of those varied during
the course of the night at times when I was dozing, or the time when I
returned to town to do email, the all-night sequence of EAR is not as
clear an indicator of propagation variance as the previous night's
captures of MLS were.

Static was not yet a factor when EAR first began materializing just a few
minutes past sunset here, and it was definitely recognizable half an hour
later (just before 6 PM).  It went away in mid-R at 6:40 AM, about an hour
before sunrise here.

A sharper version of this capture plus one at QRSS60 Slow can be found at:
