discrepancies in quality control in the Middle Kingdom. RF sensitivity depends on auto-tracking by the chip on the AM ferrite winding and on the quality and length of ferrite and winding. External aerials can compensate, but the auto-tracking is not always amused or "co-operative"... I dont have the facilities or budget, but surmise that a home-brew mechanically-tuned front-end plux mixer feeding the magic chip as IF at around 1600kHz would deliver impressive results.
