================= Magnetic Coupling experiments, 6" RFS cans ==============

Pass then Notch, 2x 195mm x 2mm wire 14mm ID coil
PocketVNA scan, 6" can.

============= Now Notch then Pass ================
Notch then pass 2x 205mm x 2mm wire 14mm ID coil
PocketVNA scan, 6" can.

These SIMPLE coupling loops are amazing!!

So easy to fabricate and adjust.
Out of band rejection, 13 to 16db for pass then notch, 16db to 20db for notch then pass.
Note, here I'm only interested in 600KHz split.
