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 was asked, yet another weird question, of how I would like to be buried, when I finally bite the big one. The answer was actually pretty easy. Face-down, like a certain historical figure in the late 1980's, (I will not mention who, but some of you will get it, and that's enough.) Why??? It would be a burial that will satisfy everyone: (1) My enemies will say that it will show me where to go. (2) On the same point, I can have my enemies kiss my butt. (3) It will temporarily give someone a place to park a bicycle. See??? A WIN / WIN for everyone.

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.
