Hi.
How to push a crystal radio design for superb sensitivity, selectivity, and audio output...
What can be done nearing the absurd to achieve extremes, like massive ferrite rods of what kind and dimensions, diametre of coils, selected diode, perhaps a piezo speaker...
Within reality, a truck size coil can be beyond the scope, but hey!, if it justifies having such, worth keeping in mind.
