[RGK20m3]

Built one, 20x22”, 2” between loops- installed on a pivot inside the cabinet of my 38-7 that allows maybe 30 degrees movement in each direction. Very impressive performance and the pivot allows a good measure of noise cancellation, although maybe not as much gain as the tuned loop that I built previously.
   
Interesting phenomenon is that the placement of the power cord is extremely critical; from totally unlistenable over most of the dial, to the exact opposite- absence of any noise. It seems that if the cord is vertical in line with the pivot that it is quiet.
Ground screw is attached to the grounding cavity of the wall outlet as no ground rod is practical and no metal piping here.
Anyone have any experiences like that? Not my build, but what I based mine off of.
