This receiver uses a tuning circuit that is, in some ways, similar to an antenna matching deviceused by amateur-radio operators to impedance-match their receiver/transmitter input/output Circuitry to the impedance of the antenna for maximum signal transfer, Inductor L2 provides a dc-signal return path for D1's output The inductance of L2 is too large to affect the circuit's tuning function.
