Hi Pete,
You've received good advice here.
Do you have a rotator on your K9AY loop? It has a deep null in one
direction, which null should be aimed at your low-angle QRN or QRM source.
Disclaimer: I never used one (since I have 580' Beverages). However, over
the years I have read many, many testimonials in favor of it.
73, Mike
