I wonder if the Chinese DE31 is a slightly simplified version of Sony's
tunable loop antenna described in Sony's U.S. patent (6,054,965). Does
anyone have a schematic of the DE31?

The only source for a DE31 appears to be direct from mainland China at a
total cost of about $30. Are there any other sources?
