I will add that my termination resistance adjustment did work well. It would show significant changes in the depth of nulls.

Atmospheric noise is 1-2 S units more on my inverted L than on the K9AY antenna, but signal strengths of stations in the favored direction of the loop seem about the same or a bit lower than the inverted L.  The Termination adjustment is working, to judge by the switching transients, but seems to make little or no difference.
