Title: Martin builds a simple ferrite MW rod to inductively couple radios to!

https://swling.com/blog/2023/09/martin-builds-a-simple-ferrite-rod-to-inductively-couple-radios-to-his-external-mediumwave-antenna/     This looks a lot more portable than that godzeye antenna that I've built a decade ago. And yes, SWL'ing rip.

I suspect many here already have a solution on their shelves, even if they are not already aware. The popular Tecsun AN-200 loop can work as an inductive MW coupler. Just connect the whatever external antenna feedline to the AN-200 1/8"-jack antenna port. IIRC, even with my old 148' loop-on-ground connected, the AN-200 still had some circuit Q to further help peak the tune.
