Hey Doug,
I miscalculated UTC time to AZ time and missed your window this
evening.
However, between 7:30pm and 8:00pm local, I did hear some fast CW but
could not read any of it, it was to faint.  Lots of static and
lightning crashes here tonight.  Spectran did not show anything clear
either.  I beleive I just barely heard you if you were transmitting
very fast CW.  Will try again at 4:00am if I can get up that early.
