Stefan:

No noise blanking or noise reduction enabled and changed to a slower 
scroll rate later.  Sound card sample rate was locked to GPS.  QRN 
last night was pretty awful.  Thanks for the tips.  Ok on further 
tests.  Conditions will surely improve as we get more into the fall 
season.  I'll start earlier in the evening next time.
73,
Bill VE2IQ
