From John A:

>At 9:00 AM, it's LSB over USB by 6.7.

>At 3:30 PM, LSB leads USB by 4.5 dB.

Thanks John. I raised the test loop a couple of feet just before your 3:30 
pm reading and I noticed I had to do some retuning, but not sure why. Either 
the big loop or the house is having an effect. Lloyd's captures from last 
night indicate no effect from disconnecting the big loop but there sure is a 
lot of difference in the two strengths in these captures (both ways) 
depending on the time. I'm about to drive SW of here to see what the 
differential is. There ought to be some reading that makes some sense!
