A really good amateur project would be to combine the smart controller
of a modern auto-ATU with your own individual collection of large
inductors, capacitors and relays. However, it would take some guts to
buy an auto-tuner, remove all the undersized RF components, measure
their inductances and capacitances, and then throw them away!

And then install a foot long hi-Q air core coil where
once rested a toroidal coil. :-)

Yes, that's the idea... well, roughly the idea...
