Hi all:  Here is Todd's report on the lowFER groundwave experiment:
_____________________________________________________________________

Hi Andy,
I got home from work and checked the ARGO screen captures for the day.
 
It looks like there was a sharp dropoff in signal as usual around 
7:15AM EDT my time or right around sunrise. I see it looks like QRSS120
held on to your signal a bit longer than QRSS60 does around sunrise.
 
It looks like the band recovered a bit a little later in the morning 
and copy was so-so up until around noon-1PM. Then by mid-afternoon I
pretty well lost your signal even on QRSS120, so it looks like it didn't
quite bring you up to solid copy all day long, but it held on to your
signal quite a bit longer than QRSS60 does.
 
I do know band conditions can change from day-to-day on extreme long-range
groundwave and can even change from hour-to-hour so it is possible on 
another day your signal might hold up most of the day, but we are not up
to 100% reliability yet.
 
Thanks for running the test and maybe with a few more tweaks we can get
a reliable groundwave signal out to 300 miles.
 
I have enclosed 3 screenshots of XR for today on QRSS120 ARGO.
