Close up photo of 4” ferrite (mix 61) rod, wrapped slightly loosely about 57 turns with 23AWG magnet wire. The pickup is 2 turns of 18AWG, & is halfway between the bottom end of the primary coil (oriented vertically), and the bottom end of the rod.

Photo not as close, so you can see the ferrite is scotch-taped to the window about 6’ off the floor/ground. The leads of the primary coil come off the right side of the rod, then extend about 3 feet to the desktop, then attach to the variable air capacitor. These leads run parallel to each other, kept about 3 inches apart by also being taped to the window.

Next ferrite rod loop RX #antenna test setup for #160meters has the ferrite rod taped to the window so that half the world isn’t blocked by the metal-cased ham gear on the workbench. Eager to see how #WSPR does overnight.
